Differential Pressure Transducers

Model 235 Wet-to-Wet transducers handle the differential pressure measurement of liquids or gases in applications with line pressures up to 2,500 psig.

The sensors use patented, inductive sensing technology in which the absence of a liquid-filled diaphragm eliminates batch contamination and thermal transient errors. The wetted parts exposed to media are stainless steel, alumina ceramic, and glass. The devices are accurate to ±0.18% of fullscale output with a total error band of ±0.5% full scale over the compensated 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.
