The Series 629 Wet/Wet differential pressure transmitter has a pressure sensor that offers 0.5-percent full-scale accuracy on ranges from 10 to 100 PSID, the company says. Units sense the differential pressure of compatible gases or liquids and send a 4-20-mA output signal. It can be used in a variety of applications with wetted parts of 316 and 316L stainless steel and comes in an industrial NEMA 4X housing, designed to withstand temperatures up to 200 degrees F (93 degrees C). According to the manufacturer, the Series 629 is the ideal transmitter for monitoring differential pressures on HVAC equipment such as water chillers, coils, heat exchangers, and pumps.
