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. Two output versions are offered: A voltage output of 5 VDC FSO (Full Scale Output) and 10 VDC FSO ), and a current output of 4 to 20 mA. Note: These instructions are also available on our website at www.setra.com. 1.1 EMC Certification This product complies with EN61326 Electrical Equipment for Measurement, Control and Laboratory use – EMC Requirements for Minimum Requirements and Industrial Locations. Special caution should be taken to meet Standard EN61000-4-5: 1995 Surge Immunity if any of the following conditions apply to the installation: The product is installed outside; all or any part of the cable is exposed to the outside; the cable is greater than 30 meters in length. In order to meet the Surge Immunity requirements, the following conditions must be followed during installation: 1. Shielded cable must be used, and the shield must be tied to earth ground (not power supply ground) on at least one end of the cable shield/drain wire. The shield must be maintained all the way from sensor to the power supply. 2. If unshielded cable is used, an earth grounded metal conduit fitting can be used to replace the shielded cable. 3. For a sensor with a metal body or enclosure, the body/enclosure must be grounded to earth. If a protective metal housing is used, the metal housing should be grounded to earth 4. If a protective plastic housing is used, the housing must be able to withstand at least 2 KV from the housing to earth ground, without damaging the circuit. 2.0 MECHANICAL INSTALLATION 2.1 Media Compatibility Model 224 transducers are designed to be used with any gas or liquid compat- ible with 316L Stainless Steel. Never submerge the transducers in any liquid. 2.2 Environment The operating temperature limits of the 224 are as follows: Operating Temperature Range°F (°C) -40 to +185 (-40 to +85) Compensated Temperature Range°F (°C) +15 to +150 (-9 to +65) Current unit ordered with Option N1: Operating Temperature Range°F (°C) -22 to +176 (-30 to +80) Compensated Temperature Range°F (°C) +15 to +150 (-9 to +65) 2.3 Pressure Fittings Mounting - Model 224 pressure transducers can be installed with Face Seal Fittings or can be butt welded into place. 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. NOTE: Welding purge gases are very hot! It is important to flow hot purge gases away from the transducer. Disconnect all electrical connections to transducer when welding.

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. Diagram 1 Note: Model 224 can be wired as a 3-wire device by connecting – OUTPUT and –EXCITATION and drain wire to a common ground. However, accuracy may be reduced due to increase in resistance. 3.2 Current Output Units The Model 224 is a two-wire loop-powered 4 to 20mA current output unit and delivers rated current into any external load of 0-800 ohms. The Model 224 is available with 6ft. of multiconductor cable, Bayonet, Mini Din, or D-Sub style connectors. Diagram 2 shows electrical connection wiring for current output transducers. The power supply must be a DC voltage source with a voltage range between 10 VDC and 30 VDC measured between the + and - terminals. The unit is calibrated at the factory with a 24 VDC loop supply voltage and a 250 ohm load. 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 integral connectors (e.g., on Bayonet, D-sub, or MiniDin Connector types), 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).

output voltage or current and should require no field adjustment. For absolute pressure ranges, the zero can be adjusted with full vacuum applied to the pressure port. For compound ranges, the zero should be adjusted with the unit at atmospheric pressure and the output adjusted as noted in Diagrams 5 & 6 on pages 5 & 6. Zero and span adjustments can be made by removing the zero and span hole plugs and washers and adjusting the zero and span potentiometers. Be certain to replace the zero and span hole plugs and washers after adjustments are made. Hole plugs and washers are installed in potentiometer holes to keep contaminants out of the unit.

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. For absolute pressure ranges, the zero should be adjusted with a full vacuum applied. See the chart below for nominal “installed” output at atmospheric pressure for compound pressure ranges.

(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. The span (full scale) output is factory set to within ±25mV for 5 VDC FSO or ±50mV for 0 to 10 VDC FSO. 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 (±0.08mA). 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 6 below. Note: When it is not possible to vent input pressure for zero adjustment (i.e., hazardous gasses), zero may be adjusted by pulling a vacuum and setting the unit to 4.0 mA (±0.08 mA). This method may result in a small zero setting error due to variations in barometric pressure. 4.4 Current Output Span Adjustment 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. The span (full scale) output is factory set to within ±0.08mA. 5.0 MODEL 224 PERFORMANCE SPECIFICATIONS NOMINAL “INSTALLED” OUTPUT AT ATMOSPHERIC PRESSURE PSI COMPOUND CURRENT RANGE OUTPUT (mA) -14.7 to 25 9.92 -14.7 to 50 7.63 -14.7 to 100 6.05 -14.7 to 250 4.89 -14.7 to 500 4.46 -14.7 to 1000 4.23 -14.7 to 3000 4.08 BAR COMPOUND CURRENT RANGE OUTPUT (mA) -1 to 1.7 9.92 -1 to 3.4 7.63 -1 to 7 6.00 -1 to 17 4.88 -1 to 35 4.44 -1 to 70 4.22 -1 to 200 4.07 Diagram 6 Accuracy RSS* Thermal Effects (at constant temperature.) ±0.25% FS Comp Range °F(°C) +15 to +150 (-9 to +65) Non-Linearity, BFSL ±0.15% FS Zero Shift %FS/100°F (50°C) ±2.0 (±1.8) Hysteresis 0.20% FS Span Shift %FS/100°F (50°C) ±2.0 (±1.8) Non-Repeatability 0.02% FS Environmental Data (Temperature) *RSS of Non-Linearity, Non-Repeatability and Hysteresis.
