Setra Model 224 Ultra High Purity Flow-Through Pressure Transducer 1.0 GENERAL INFORMATION Every Model 224 has been tested and calibrated before shipment. Model 224 performance specifications are listed on Page 6 of this Guide. Setra Systems 224 pressure transducers sense gauge, compound or absolute pressure and convert this pressure to a proportional high level analog output.
2.4 Venting Model 224 transducers are vented through the electronics housing. 3.0 ELECTRICAL INSTALLATION 3.1 Voltage Output Units The Model 224 voltage output transducer is supplied with a 6ft. multiconductor cable, Bayonet style connector, Mini Din connector, or D-Sub style connectors. The voltage output is either 5 VDC FSO or 10 VDC FSO. Diagram 1 shows electrical connection wiring for voltage output transducers, and the excitation required.
Note 1). The transducer case and integral Bayonet Connector shell, D-sub Connector Shell, and Mini Din shell clips are electrically connected. Note 2: ETL Listed to UL1604 Standards:The current output unit (excluding units ordered with the Mini Din Shell) may be installed in UL1604 Class 1 Hazardous (Classified) Group A, B, C, D, Division 2 locations if the unit is ordered for these locations. (This is denoted by an N1 designation in the Part Number, 12th and 13th digits.
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.
4.2 Voltage Output Span Adjustment (Complete the zero adjustment before setting span.) Span or full scale output adjustments should only be performed by using an accurate pressure standard (electronic manometer, digital pressure gauge, etc.), with at least comparable accuracy to the 224 transducer (±0.25% FS). With full range pressure applied to the pressure port, the span may be adjusted by turning the span potentiometer screw.
