14 General safety notes 2.7 Qualified Personnel CAUTION Electrostatic Sensitive Devices (ESD) This device contains electrostatic sensitive devices. Electrostatic sensitive devices may be destroyed by voltages that are undetectable to a human. Voltages of this kind occur as soon as a component or an assembly is touched by a person who is not grounded against static electricity. The damage to a module as a result of overvoltage cannot usually be detected immediately. It may only become apparent after a long period of operation. Protective measures against discharge of static electricity: Make sure that no power is applied. Before you work with modules, first discharge any static charges from your body, for example by touching a grounded object. Devices and tools used must be free of static charge. Hold modules only by their edges. Do not touch connector pins or conductor tracks on a module with the ESD notice. 2.7 Qualified Personnel Qualified personnel are people who are familiar with the installation, mounting, commissioning, and operation of the product. These people have the following qualifications: They are authorized, trained or instructed in operating and maintaining devices and systems according to the safety regulations for electrical circuits, high pressures and aggressive as well as hazardous media. For explosion-proof devices: They are authorized, trained, or instructed in carrying out work on electrical circuits for hazardous systems. They are trained or instructed in maintenance and use of appropriate safety equipment according to the safety regulations. 12 Operating Instructions, 09/2010, A5E

15 Description System configuration Overview The pressure transmitter can be used in a number of system configurations: as a stand-alone version, supplied with the necessary auxiliary power as part of a complex system environment, e.g. SIMATIC S7 System communication Communication is via the HART protocol, using: HART Communicator (load Ω) PC with HART modem, on which appropriate software is installed, e.g. SIMATIC PDM (load Ω) Control system which can communicate via the HART protocol, e.g. SIMATIC PCS7 Figure 3-1 Possible system configurations Operating Instructions, 09/2010, A5E

16 Description 3.2 Application range 3.2 Application range Overview Depending on the variant, the pressure transmitter measures corrosive, non-corrosive and hazardous gases, vapors and liquids. With appropriate parameterization, you can also use the differential pressure transmitter for the following measurement types: Level Volume Mass Volume flow Mass flow The output signal is always a load-independent direct current between 4 and 20 ma upon which a HART protocol is superimposed. You can install the "Intrinsically safe" or "Flameproof enclosure" version of the transmitter in hazardous areas. The devices have an EC type-examination certificate and meet the regulations applicable to them, for example, the harmonized CENELEC standards in Europe. Transmitters with remote seals of different shapes can be delivered for special applications. For example, measuring high-viscosity substances is a special application. Differential pressure and flow rate This version measures corrosive, non-corrosive and hazardous gases, vapors and liquids. You can use this version for the following measurement types: Differential pressure Positive or negative relative pressure In combination with a restrictor device: flow rate q ~ p The smallest differential pressure span is 1.25 mbar (0.5 inh2o); the largest differential pressure span is 1250 mbar (502 inh2o). Level This version with mounting flange measures the level of non-corrosive, corrosive and hazardous liquids in open and closed containers. The smallest measuring span is 1.25 mbar (0.5 inh2o); the largest span is 1250 mbar (502 inh2o). The nominal diameter of the mounting flange is DN 80 or DN 100 or 3" or 4". The negative connection of the measuring cell is kept open when measuring the level of open containers. This measurement is referred to as "measurement against atmosphere". The negative connection is normally connected with the container when measuring the level of closed containers. This balances the static pressure. Wetted parts are made of various materials, depending on corrosion resistance requirements. 14 Operating Instructions, 09/2010, A5E

20 Description 3.5 Functional principle 3.5 Functional principle Operation of the electronics Description 1 Measuring cell sensors 7 HART modem 2 Measuring amplifier 8 Buttons (local operation) 3 Analog-to-digital converter 9 Display 4 Microcontroller 5 Digital-to-analog converter IA Output current 6 Each with an EEPROM in the measuring UH Auxiliary power cell and in the electronics Figure 3-4 Operation of electronics with HART communication, simplified illustration Function The input pressure is converted into an electrical signal by the sensor 1. This signal is amplified by the measuring amplifier 2 and converted in an analog-todigital converter Operating Instructions, 09/2010, A5E

21 Description 3.5 Functional principle The digital signal is analyzed in a microcontroller 4 and corrected with regard to linearity and thermal characteristics. It is then converted in a digital-to-analog converter 5 to the output current of 4 to 20 ma. A diode circuit provides reverse polarity protection. The measuring cell specific data, electronics data and parameterization data are saved in two EEPROM 6. One EEPROM is located in the measuring cell, the other is incorporated in the electronics. Operation Use the keys 8 to navigate and set different parameters. If your device has a display 9, you can perform the parameter settings locally and track messages from the device visually. Other settings can be implemented with a computer using a HART modem Measuring cell operation CAUTION Toxic and hot media leaks If the measured signal fails because of sensor breakage, the seal diaphragm and the overload system may also be destroyed. In the worst case scenario of devices with a destroyed seal diaphragm, the process medium leaks on the side ventilated with reference pressure. In case of sensor breakage, deactivate the lines to the device or depressurize the lines. In the following sections, the process variable to be measured is called general inlet pressure. Overview The following principles of operation are described: Differential pressure and flow rate Level The following process connections are available, for example: ¼ - 18 NPT Flanged connection In accordance with EN Operating Instructions, 09/2010, A5E

22 Description 3.5 Functional principle Measuring cell for differential pressure and flow rate 1 Silicon pressure sensor 6 Overload diaphragm 2 Inlet pressure P+ 7 Filling liquid 3 Process flange with process connection 8 Seal diaphragm 4 O-ring 9 Inlet pressure P- 5 Measuring cell body Figure 3-5 Function diagram of the measuring cell for differential pressure and flow rate The differential pressure is transmitted via the seal diaphragm 8 and the fill fluid 7 to the silicon pressure sensor 1. If the measuring limits are exceeded, the seal diaphragm 8 is displaced so far that it lies against the bodies of the measuring cell 5. This protects the silicon pressure sensor 1 against overload. Differential pressure causes the measuring diaphragm of the silicon pressure sensor to be displaced. The displacement changes the resistance value of the four piezo resistors in the measuring diaphragm in a bridge circuit. The change in the resistance causes a bridge output voltage proportional to the differential pressure. 20 Operating Instructions, 09/2010, A5E

23 Description 3.5 Functional principle Measuring cell for level 1 Process flange with process connection 6 Filling liquid of the measuring cell 2 O-ring 7 Seal diaphragm in the measuring cell 3 Silicon pressure sensor 8 Capillary tube with the fill fluid of the mounting flange 4 Measuring cell bodies 9 Flange with a tube 5 Overload diaphragm 10 Seal diaphragm on the mounting flange Figure 3-6 Function diagram of the measuring cell for level The input pressure (hydrostatic pressure) acts hydraulically on the seal diaphragm at the mounting flange 10 on the measuring cell. The differential pressure existing at the measuring cell is transmitted via the fill fluid 6 to the silicon pressure sensor 3. If the measuring limits are exceeded, the seal diaphragm on the measuring cell 7 is displaced so far that it lies against the bodies of the measuring cells 4. This protects the silicon pressure sensor 3 against overload. Differential pressure causes the measuring diaphragm of the silicon pressure sensor to be displaced. The displacement changes the resistance value of the four doped piezo resistors arranged in a bridge circuit in the measurement diaphragm. The change in resistance causes the bridge output voltage to vary in proportion to the differential pressure. Operating Instructions, 09/2010, A5E

24 Description 3.5 Functional principle Remote seals Product description A remote seal measuring system comprises the following elements: Remote seal Transmission line, e.g. capillary line Measuring device NOTICE Malfunction of the remote seal measuring system If you separate the components of the remote seal measuring system, this results in malfunctioning of the system. Do not separate the components under any circumstances. The measuring system based on a hydraulic principle is used to transfer pressure. The capillary line and the remote seal diaphragm are the most sensitive components in the remote seal measuring system. The material thickness of the remote seal diaphragm is only 0.1 mm. The smallest of leakages in the transmission system leads to the loss of transmission fluid. The loss of transmission fluid results in inaccuracies in the measurement and failure of the measuring system. In order to avoid leaks and measuring errors, please observe the installation and maintenance instructions in addition to the safety notes. 22 Operating Instructions, 09/2010, A5E

See Measuring accuracy (Page 178). 28 Operating Instructions, 09/2010, A5E

31 Install 4.3 Sealing connecting elements 4.3 Sealing connecting elements Siemens optionally delivers a metric thread M20 x 1.5 or a conical thread 1/2-14 NPT for the cable gland or the blanking plug. The metric threads are sealed using O-rings as standard. If you are using flat gaskets for a M20 x 1.5 thread, improper mounting can result in sealing problems. Instructions for the sealing methods: Thread sealant For metric and tapered threads To seal the thread, use suitable liquid sealant, e.g. Loctite. Completely remove all the sealant residue when resealing the threads following disassembly. Check the thread for possible damage and replace the damaged parts. During installation, make sure that the cable gland or the blanking plug is completed screwed in. Teflon tape For tapered thread only Make sure that you do not wrap the Teflon tape around threads more than two to three times. We recommend using tape with a thickness of 0.1 mm. If you use thicker tape, you must reduce the number of wraps. Count the threads in the engagement length. Make sure that when you screw in the cable gland with Teflon tape that the total number of threads has not been reduced by more than one thread. Flat gasket For metric thread only Make sure that the flat gasket has a maximum thickness of a thread lead. For example, the flat gasket for a M20 x 1.5 thread has a maximum thickness of 1.5 mm (0.06"). Count the threads in the engagement length. Make sure that when you screw in the cable gland with the flat gasket that the total number of threads has not been reduced by more than one thread. Operating Instructions, 09/2010, A5E

38 Install 4.6 "Remote seal" installation 4.6 "Remote seal" installation Remote seal installation General installation instructions Keep the measuring system in the factory packing until it is installed in order to protect it from mechanical damage. When removing from the factory packing and installing: ensure that damage to and mechanical deformations in the membrane are prevented. Never loosen the sealed filling screws on the remote seal and the measuring instrument. Do not cause damage to the remote separating membrane; scratches on the remote separating membrane, e.g. due to sharp-edged objects, are the main starting points for corrosion. Select suitable gaskets for sealing. Use a gasket having an adequately large inner diameter for flanging. Insert the gasket concentrically; contact with the membrane leads to deviations in measurements. When using gaskets made of soft materials or PTFE: follow the guidelines of the gasket manufacturer, especially regarding the tightening torque and setting cycles. At the time of installation, use suitable fastening components such as screws and nuts that are compliant with fitting and flange standards. Excessive tightening of screwed joints on the process connection may displace the zero point on the pressure transmitter. Note Commissioning If a shut-off valve exists, open the shut-off valve slowly when commissioning in order to avoid pressure surges. Note Permissible ambient and operating temperatures Install the pressure measuring device such that the permissible limits of ambient and measured medium temperatures are not overshot or undershot even with the consideration of the effect of convection and heat radiation. Note the effect of temperature on the measuring accuracy. When selecting the remote seals, ensure that fittings and flange components have adequate pressure-temperature resistance by selecting suitable materials and pressure ratings. The pressure rating specified on the remote seal applies to reference conditions according to IEC For the maximum permissible pressure at higher temperatures, please refer to the standard specified on the remote seal. 36 Operating Instructions, 09/2010, A5E

39 Install 4.6 "Remote seal" installation Using remote seals with pressure measuring device for hazardous areas: When using remote seals with pressure measuring device for hazardous areas, the permissible limits of ambient temperatures for the transmitter must not be exceeded. Hot surfaces on the cooling section (capillaries or cooling elements) are a possible source of ignition. Initiate suitable measures. When remote seals with a flame arrestor are used, the pressure measuring instrument determines the permissible ambient temperature. In the case of potentially explosive gaseous atmosphere, the temperature around the flame arrestor must not exceed +60 C Installation of the remote seal with the capillary line Notes Do not rest the measurement assembly on the capillary line. Do not bend capillary lines; risk of leakages and/or risk of considerable increase in the response time of the measuring system. Owing to the risk of bending and breakages, pay attention to mechanical overloads at the joints such as capillary line-remote seal and capillary line-measuring instrument. Unwinding the excess capillary lines with a radius of at least 150 mm. Fasten the capillary line such that there are no vibrations. Permissible height differences: When installing the pressure measuring instrument above the measuring point, keep the following in mind: in the case of remote seal measuring systems with silicone, glycerin or paraffin oil filling, the maximum height difference of H1max = 7 m must not be exceeded. If halocarbon oil is used as a fill fluid, this maximum height difference is H1max = 4 m, see installation type G. If negative overpressure is observed during measurements, reduce the permissible height difference accordingly. Operating Instructions, 09/2010, A5E

45 Connecting Safety notes for connection For all devices WARNING If auxiliary power is required, check that it corresponds with that on the nameplate and with the test certification valid for your country. CAUTION Incorrect measurement values due to incorrect grounding It is not permissible to ground the device using the "+" connection. This can lead to malfunctions with permanent damage to the device. If necessary, ground the device using the "-" connection. General explosion protection WARNING Risk of explosion Non-compliance with the stipulations and laws during connection and installation increases the risk of explosion due to improper use. When connecting and installing, follow only the test certifications, stipulations and laws applicable in your country in order to avoid the risk of explosion. For example, for hazardous areas these are: IEC (international) National Electrical Code (NEC - NFPA 70) (USA) Canadian Electrical Code (CEC) (Canada) EN (earlier VDE 0165, T1) (EU) Ordinance on Industrial Safety and Health (Germany) Operating Instructions, 09/2010, A5E

46 Connecting 5.1 Safety notes for connection WARNING Explosion protection Connect the device to the equipotential bonding. Free cable ends are not permitted in hazardous areas. Use suitable protection types, e.g., flameproof enclosure Ex "d" or increased safety Ex "e", to protect the free cable ends. For shielded cables in hazardous areas, note that only end is permitted to be grounded. Install a potential equalising cable if grounding on both ends is required. WARNING Cable glands The cables must be matched to the cable glands. If you use the cable glands M20 x 1.5 and ½-14" NPT, which can be ordered separately, only the cables having a diameter of 6 to 12 mm must be laid into the device. After installation, make sure that the cables are positioned securely and that the seals are in the correct position. Type of protection "na", "nl", "ic" In the case of devices with type of protection "na", "nl" and "ic" (Zone 2), only use cables having a diameter of 8 to 12 mm owing to the required tensile strength, or use a suitable cable gland in case of smaller diameters. CAUTION Cable damage Insulation on cables can be damaged if they are used in elevated ambient temperatures. For this reason, if cables are to be operated in an ambient temperature T 60 C, use heat-resistant cables approved for an ambient temperature at least 20 K higher. Also, ensure that you use appropriate cables for operation in low temperatures. WARNING The inlet openings for the electrical connections must be sealed. For this purpose, use only cable glands or plugs that are suitable for the type of protection that is required. 44 Operating Instructions, 09/2010, A5E
