2.0 MECHANICAL INSTALLATION
2.1 Media Compatibility
Model 231RS transducers are designed to be used with any gas or liquid compatible with 17-4 PH stainless steel. Nev-
er totally submerge the unit in any liquid.
2.2 Environment
The operating temperature limits of the Model 231RS are as follows:
Compensated Temperature Range °F (°C) +32 to +130 (0 to +54)
Operating Temperature Range °F (°C) -4 to +185 (-20 to +85)
Storage Temperature Range °F (°C) -4 to +185 (-20 to +85)
2.3 Pressure Fittings
Typically standard pipe fittings and installation procedures should be used.
Model 231RS have 1/4” -18” NPT male fittings. The high pressure port and low pressure connections are located on the
bottom of the unit, labeled “HI(+)” and “LO(-)” respectively.
Important:
Each remote sensor is labeled “HIGH PRESSURE SENSOR” or “LOW PRESSURE SENSOR”. Match up the high pressure
sensor to the high pressure electrical terminals, and the low pressure sensor to the low pressure electrical terminals.
Otherwise, the performance may not meet the product linearity specifications.
Moisture Precautions
The Model 231RS is provided with a 0.875” DIA. conduit opening for electrical termination, intended for a 1/2” I.D.
conduit connection. This opening must be sealed according to standard industry practices in order to prevent mois-
ture ingress into the Model 231RS.
