Multi-Sense® Model 231RS Series
Wet-to-Wet Differential Pressure Transducers
1.0 GENERAL INFORMATION
Every Model 231RS has been calibrated and tested before shipment to guarantee performance of all pressure ranges.
The Model 231RS has field selectable unidirectional and bidirectional pressure ranges, configurable 0 to 5 VDC, 0 to 10
VDC , and 1 to 5 VDC output, true two-wire 4 to 20 mA output, and auto-zero capability. Each unit is factory calibrated
to the highest pressure range. The range label on the side of the unit indicates the factory calibrated range. Reminder:
Your application’s highest line pressure should be less than or equal to the highest pressure range of the 231RS
range code you selected when you purchased the 231RS. See Range Codes in table below. (Range codes also
listed on inside of housing cover).
Model 231RS pressure transducers sense differential pressure and convert this difference in pressure to a proportional
high level analog output for unidirectional and bidirectional pressure ranges.
Your Model 231RS Multi-Sense pressure transducer has been ordered in one of the following versions:
