Differential Pressure Transducer

The Model 235 Wet-to-Wet high-line differential pressure transducer is designed for differential-pressure measurement of liquids or gases in applications with unidirectional or bidirectional line pressures to 2,500 psi

g. A fastresponse inductive sensing element gives a linear analog output proportional to pressure. The unit is accurate to ±0.18% of full-scale output with a total error band of ±0.5% full scale over the compensated temperature range of 20 to 160°F on 5 psid through 500-in. W.C. pressure ranges. Total error band on the 2-psid units is ±0.75% over the compensated temperature range. Pressure ranges are as low as 2 psid up to 500-in. W.C. The transducer comes in either an all-stainless-steel housing with cable termination or aluminum housing with terminal block.
