2 General Application The single-channel or dual-channel gas analyzers operate according to the NDIR two-beam alternating light principle and measure gases highly selectively whose absorption bands lie in the infrared wavelength range from 2 to µm, such as CO, CO 2, NO, SO 2, NH 3, H 2 O, CH and other hydrocarbons. Single-channel analyzers measure up to 2 gas components. Dual-channel analyzers measure up to gas components simultaneously ( components as special application). Special applications Besides the standard combinations special applications concerning material of the gas path, material of sample cell and sample components are also available on request. Special materials of the sample cell 36SS/titanium on request. -component analyzers are also available as special application.

4 General Mode of operation The gas analyzer operates according to the infrared two-beam alternating light principle with double-layer detector and optical coupler. The measuring principle is based on the molecule-specific absorption of bands of infrared radiation. The absorbed wavelengths are characteristic to the individual gases, but may partially overlap. This results in cross-sensitivities which are reduced to a minimum in the gas analyzers by the following measures: Gas-filled filter cell (beam divider) Double-layer detector with optical coupler Optical filters if necessary. Fig. 2 shows the measuring principle. An IR source () which is heated to approx. 700 ºC and which can be shifted to balance the system is divided by the beam divider (3) into two equal beams (sample and reference beams). The beam divider also acts as a filter cell. The reference beam passes through a reference cell (8) filled with N 2 (a non-infrared-active gas) and reaches the right-hand side of the detector () practically unattenuated. The sample beam passes through the sample cell (7) through which the sample gas flows and reaches the left-hand side of the detector (0) attenuated to a lesser or greater extent depending on the concentration of the sample gas. The detector is filled with a defined concentration of the gas component to be measured. The detector is designed as a double-layer detector. The center of the absorption band is preferentially absorbed in the upper detector layer, the edges of the band are absorbed to approximately the same extent in the upper and lower layers. The upper and lower detector layers are connected together via the microflow sensor (2). This coupling means that the spectral sensitivity has a very narrow band. The optical coupler (3) lengthens the lower receiver cell layer optically. The infrared absorption in the second detector layer is varied by changing the slider position (). It is thus possible to individually minimize the influence of interfering components. A chopper (5) rotates between the beam divider and the sample cell and interrupts the two beams alternately and periodically. If absorption takes place in the sample cell, a pulsating flow is generated between the two detector levels which is converted by the microflow sensor (2) into an electric signal. The microflow sensor consists of two nickel grids heated to approx. 20 C which, together with two further resistors, form a Wheatstone bridge. The pulsating flow together with the very close arrangement of the Ni grids leads to a change in resistance. This leads to an offset in the bridge which is dependent on the concentration of the sample gas. Note The sample gases have to enter the analyzer dustfree. Avoid condensate in the sample cells. Therefore an appropriate gas preparation is required in the most applications. The ambient air of the analyzer should be, in a large extent, free of high concentration of the component to be measured IR source, adjustable 2 Optical filter 3 Beam divider (gas filter) Eddy current drive 5 Chopper 6 Sample gas inlet 7 Sample cell Fig. 2, mode of operation 8 Reference cell Sample gas outlet 0 Detector, left Detector, right 2 Microflow sensor 3 Optical coupler Slider, adjustable Siemens Catalog Extract PA 0 November 2002

7 General Communication PROFIBUS-DP/-PA Fig. Basic structure of a PROFIBUS system The term "Field bus" describes a digital communications system with which distributed field devices in a plant are networked together via one single cable, and connected at the same time to programmable controllers or to a process control system. PROFIBUS is the leading field bus on the market. The PROFIBUS-DP version is widely used for production automation because of its high transmission rate for relatively small data quantities per device, whereas PROFIBUS-PA particularly takes into account the features required for process engineering, e.g. large data quantities and application in potentially explosive atmospheres. User benefits can be found in the extremely high potentials for cost savings in all areas of the plant, covering configuring and commissioning, operation and maintenance, and up to later plant extensions. Operation of the gas analyzers from a control system or separate PC is possible using the SIMATIC PDM (Process Device Manager) operator input tool which is software executing under Windows 5/8/NT and which can also be incorporated into the SIMATIC PCS 7 process control system. This permits clear display of both the incorporation of devices into the system and the complex parameter structure of the analyzers, permitting operation to be carried out simply by clicking. The PROFIBUS user organization (PNO) is an independent international institution, and represents the interests of many vendors and users. In addition to services such as consultation, training and device certification, its prime task is the further development, standardization and promotion of the PROFIBUS technology. The definition of a binding functionality for a device class in a profile is a prerequisite for the uniform response of devices from different vendors, the so-called interoperability. The profile for analyzers was defined as binding at the end of, thus guaranteeing the interaction of all PROFIBUS-based devices in a plant. This profile defines the functionality of the analyzers in a block model: e.g. the physical block describes the measuring procedure, analyzer and vendor names, serial number and operating state (operation, maintenance). Various functional blocks contain the execution of specific functions such as the processing of measured values or alarms. The transducer blocks describe the functionality of the actual measuring procedure and its control, e.g. preprocessing of a measured value, correction of cross-interferences, characteristics, measuring ranges as well as switching and control procedures. Protocols define the data transmission between the stations on the bus. A differentiation is made between cyclic and acyclic services. Cyclic services are used to transmit time-critical data such as measured values and statuses. The acyclic services permit the scanning or modification of device parameters during operation. All gas analyzers of Series 6, and OXYMAT 6, as well as OXYMAT 6, CALOMAT 6 and ULTRAMAT 23, are suitable for PROFIBUS when fitted with the optional plug-in card (retrofitting also possible, see Ordering information).
