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.
