Wet-to-Wet Differential Pressure Transducer
The Model 231 multi-sense wet-to-wet differential pressure transducer is suitable for monitoring control pump differential pressures, chiller or boiler differential pressure drops, and flow measurement of gasses or liquids. Its all-inclusive design reduces inventory and installation costs by providing the user with field-selectable features, such as switch-selectable pressure ranges; selectable analog outputs that include true two-wire 4 to 20 mA output; three-wire 0 to 5 VDC, 0 to 10 VDC and 1 to 5 VDC output; and uni-directional and bi-directional ranging of span in one unit. An optional LCD display is also available for in-situ reporting of range and output status. All three versions feature a dual pressure sensor design that incorporates thin film sensing technology for optimal thermal accuracy and signal linearity. Each unit has been temperature compensated from 32 F to 130 F with zero and span accurate to within 0.02% per degree F.
