Setra Systems” Model 235 wet-to-wet transducer is designed for differential-pressure measurement of liquids or gases in applications with line pressures up to 2500 PSIG. The transducer features a patented inductive sensing technology with no liquid filled diaphragm to eliminate the possibility of batch contamination and thermal transient errors. Wetted parts are stainless steel, alumina ceramic, and glass. The transducer is accurate to +/- 0.18 percent full scale with a total error band of +/- 0.5 percent full scale over the compensated temperature range of –20 F to 160 F on five PSID through 500 in. W.C. pressure ranges. Total error band on the two-PSID units is +/- 0.75 over the compensated temperature range. There is virtually no shift in output at warm-up, and an update rate of 25 ms (typical) makes the unit a good fit for pressure applications that require a stable, fast response. This unit is offered with a choice of four to 20 mA or 0.5 to 4.5 VDC output with pressure ranges as low as two PSID up to 500 in. W.C., and a choice of all stainless steel housing with cable termination or aluminum housing with terminal block. Both versions are rated for NEMA 4/IP65 operation and are ideally suited to OEM applications.
