This series of low-pressure transmitters can be used to measure positive, negative or differential pressure in ranges from 1” W.C. to 20” W.C. (250 to 2000 Pa). The piezoresistive sensor is ideal for monitoring the pressure of air or other clean inert gases and is limited only to those media which will not attack polyetherimide, silicon, fluorosilicone, silicone, EPDM, and neoprene seals.
