1 Measuring instruments for pressure SITRNS P transmitters for pressure, absolute pressure, diff. pressure, flow, level Measuing instruments for pressure S III series Fig. /0 SITRNS P transmitters, S III series for pressure, absolute pressure, differential pressure, flow and level, with visible digital display pplication Various versions of the SITRNS P transmitter, S III series, are available with a two-wire circuit. The output signal is a load-independent direct current of 4 to 0 m linearly proportional to the input pressure. Transmitters conforming to the type of protection "Intrinsic safety" and "xplosion-proof" may be installed within potentially explosive atmospheres (zone ) or zone 0. The transmitters are provided with an U prototype test certificate and comply with the corresponding harmonized uropean standards of the TX. Transmitters with the type of protection "Intrinsic safety" for use at zone 0 may be operated with power supply units of category "ia" and "ib". The transmitters can be equipped with various designs of remote seals for special applications such as the measurement of highly viscous substances. The transmitters can be programmed locally using three input keys or externally via HRT. The following table describes the fundamental parameters. Further parameters for special applications are accessible via HRT.

Spans are possible between 5 mbar (0. psi) and 5 bar (7.5 psi). The nominal mounting flange diameter is N 80 or N 00 ( or 4 inch). In the case of level measurements in open containers, the lowpressure connection of the measuring cell remains open (measurement with respect to atmosphere), while for measurements in closed containers, this connection must be connected to the container in order to compensate the static pressure. The wetted parts are constructed from a variety of materials depending on the degree of corrosion resistance required.

3 esign and mode of operation The SITRNS P transmitter, S III series, is immediately ready for operation following installation. The adjustable span corresponds to the data on the rating plate. If a customer-specific setting is made in the factory, the start-of-scale and full-scale values are printed on the rating plate. If necessary, the parameters can also be changed during commissioning using simple input operations on the transmitter. esign The transmitter consists of various components depending on the customer-specific order. The possible versions are listed in the ordering information. The rating plate (, Fig. /) with the Order No. is located on the side of the housing. The specified number together with the ordering information provide details on the optional design details and on the possible measuring range (physical properties of built-in sensor element). The approval label is located on the opposite side. The housing is made of die-cast aluminium or stainless steel precision casting. round cover is screwed on at the front and rear. The front cover () can be fitted with a viewing pane so that the measured values can be read directly on the digital display. The inlet (4) to the electrical junction box is located either on the left or right side. The unused opening in each case is sealed by a blanking plug. The protective earth connection is located on the rear of the housing. The electrical junction box for the power supply and screen is accessible by unscrewing the rear cover. The bottom part of the housing contains the measuring cell with process connection (). This is protected from rotating by a locking screw (8). The modular design of the SITRNS P, S III series, means that the measuring cell and electronics can be replaced if necessary. The set parameter data are retained. t the top of the housing is a plastic cover (5). The input keys are located underneath this cover. Mode of operation Mode of operation of the electronics The input variable is converted by the sensor (, Fig. /) into an electric signal which is amplified by the instrument amplifier () and digitized in an analog-to-digital converter (). The digital information is evaluated in a microcontroller, its linearity and temperature response corrected, and converted in a digital-toanalog converter (5) into the output current of 4 to 0 m. diode circuit (0) protects against incorrect polarity. The data specific to the measuring cell, the electronics data, and the parameter data are stored in two non-volatile memories (). The first memory is coupled to the measuring cell, the second to the electronics. Replacement of the electronics and/or the measuring cell is therefore possible (modular design). The three input keys (8) can be used to directly parameterize the transmitter at the position of measurement, and also to view results, error messages and operating modes on the digital display (9). The HRT modem (7) permits parameterization using a protocol according to the HRT specification. 8 M 4 m HRT interface PROM lectronics 0 I, U H Sensor PROM P e Measuring cell Measuring cell sensor Instrument amplifier nalog-to-digital converter 4Microcontroller 5 igital-to-analog converter One non-volatile memory each in the measuring cell and electronics 7 HRT interface 8 Three input keys (local operation) 9 igital display 0 iode circuit and connection for external ammeter I Output current U H Power supply P e Input variable Fig. / SITRNS P transmitter, S III series, electronics Fig. / SITRNS P transmitter for pressure, S III series, front view icenta ontrols Ltd SITRNS P Pressure Transmitters page of 0 Tel: Fax: mail: info@icenta.co.uk

4 SITRNS P transmitter, S III series, for pressure The pressure p e is applied via the process connection (, Fig. /) to the measuring cell (). It is transmitted further via the seal diaphragm () and the filling liquid (4) to the silicon pressure sensor (5) whose measuring diaphragm is then flexed. The resistance of four piezo-resistors fitted in the diaphragm in a bridge circuit thus changes. This change in resistance results in a bridge output voltage proportional to the input pressure. The pressure transmitters with spans bar ( 94 psi) measure the input pressure compared to atmospheric, transmitters with spans 0 ( 0 psi) compared to a vacuum. SITRNS P transmitter, S III series, for absolute pressure, from the differential pressure series The absolute pressure is transmitted via the seal diaphragm (, Fig. /5) and the filling liquid (8) to the silicon pressure sensor (). If the measuring limits are exceeded, the overload diaphragm () is flexed until the seal diaphragm rests on the body of the measuring cell (7), thus protecting the silicon pressure sensor from overloads. The difference in pressure between the input pressure (p e ) and the reference vacuum () on the lowpressure side of the measuring cell flexes the measuring diaphragm. The resistance of four piezo-resistors fitted in the diaphragm in a bridge circuit thus changes. This change in resistance results in a bridge output voltage proportional to the absolute pressure. 5 4 p e Measuring cell Process connection Seal diaphragm 4Filling liquid 5 Silicon pressure sensor P e Pressure as input variable P e Reference vacuum Overload diaphragm Silicon pressure sensor 4O-ring 5 Process flange Seal diaphragm 7 ody of measuring cell 8 Filling liquid P e bsolute pressure as input variable Fig. / Measuring cell for pressure, functional diagram SITRNS P transmitter, S III series, for absolute pressure, from the pressure series The absolute pressure is transmitted via the seal diaphragm (, Fig. /4) and the filling liquid (4) to the silicon absolute pressure sensor (5) whose measuring diaphragm is then flexed. The resistance of four piezo-resistors fitted in the diaphragm in a bridge circuit thus changes. This change in resistance results in a bridge output voltage proportional to the absolute pressure. Fig. /5 Measuring cell for absolute pressure from differential pressure series, functional diagram SITRNS P transmitter, S III series, for differential pressure and flow The differential pressure is transmitted via the seal diagrams (, Fig. /) and the filling liquid (7) to the silicon pressure sensor (4). If the measuring limits are exceeded, the overload diaphragm () is flexed until one of the seal diagrams rests on the body of the measuring cell (), thus protecting the silicon pressure sensor from overloads. The measuring diaphragm is flexed by the applied differential pressure. The resistance of four piezoresistors fitted in the diaphragm in a bridge circuit thus changes. This change in resistance results in a bridge output voltage proportional to the differential pressure. 5 4 P e Measuring cell Process connection Seal diaphragm 4Filling liquid 5 Silicon absolute pressure sensor P e bsolute pressure as input variable Seal diaphragm O-ring Overload diaphragm 4Silicon pressure sensor 5 Process flange ody of measuring cell 7 Filling liquid Fig. /4 Measuring cell for absolute pressure from the pressure series, functional diagram Fig. / Measuring cell for differential pressure and flow, functional diagram icenta ontrols Ltd SITRNS P Pressure Transmitters page 4 of 0 Tel: Fax: mail: info@icenta.co.uk

5 SITRNS P transmitter, S III series, for level The input pressure (hydrostatic pressure) acts hydraulically on the measuring cell via the seal diaphragm on the mounting flange (, Fig. /7). The differential pressure applied to the measuring cell is transmitted via the seal diaphragm () and the filling liquid (9) to the silicon pressure sensor (). If the measuring limits are exceeded, the overload diaphragm (5) is flexed until the seal diaphragm rests on the measuring cell body (4), thus protecting the silicon pressure sensor from overloading. The measuring diaphragm is flexed by the differential pressure. The resistance of four piezo-resistors fitted in the diaphragm in a bridge circuit thus changes. This change in resistance results in a bridge output voltage proportional to the differential pressure Parameterization epending on the version, there are different possibilities for parameterizing the transmitter and for setting or scanning the parameters. Parameterization using the input keys (local operation) The input keys can be used to simply set the most important parameters without any additional equipment. Parameterization using HRT communication When parameterizing with the HRT communicator, the connection is made directly to the two-wire system (Fig. /8). When parameterizing with a laptop or P, the connection is made via a HRT modem (Fig. /9).
