Setra Model 223 Ultra High Purity Flow-Through Pressure Transducer 1.0 GENERAL INFORMATION Every Model 223 has been tested and calibrated before shipment. Model 223 performance specifications are listed on Page 6 of this Guide. Setra Systems 223 pressure transducers sense gauge, compound or absolute pressure and convert this pressure to a proportional high level analog output.
When installing units with Face Seal Fittings: a) Align piping system to transducer connections b) Hand tighten nuts c) Torque nuts by placing wrenches on nuts only (or on nut and wrench flats of transducer body for units with fixed male face seals) Never hold the unit by the electronics housing during installation. 2.4 Venting Model 223 transducers are vented through the electronics housing. 3.0 ELECTRICAL INSTALLATION 3.
Current must flow in one direction only - Please observe polarity. (See Diagram 3.) We suggest that the cable shield Drain Wire be connected to the system’s loop circuit ground for optimum electrical noise rejection. On transducers with an integral Bayonet connector, connection to transducer case ground can be achieved by connecting the cable drain/shield wire to the mating cable-mounted connector shell (see Note 1).
4.1 Voltage Output Zero Adjustment While monitoring the voltage between the positive output (+OUT) and common (COM), and with the pressure port open to atmosphere, or with zero pressure applied, the zero may be adjusted by turning the zero potentiometer screw. For the 5 VDC Full Scale Output, the tolerance on zero and span settings is ±25mV. For the 10 VDC Full Scale Output, the tolerance on zero and span settings is ±50mV.
4.3 Current Output Zero Adjustment While monitoring the current output , and with the pressure port open to atmosphere or with zero pressure applied, the zero may be adjusted by turning the zero potentiometer screw. The factory setting is 4mA (±0.08 mA). For absolute pressure ranges, the zero should be adjusted with a full vacuum applied. For compound pressure ranges, the zero should be adjusted with the unit at atmospheric pressure and the output adjusted as noted in Diagram 5 below.
