PSE531 and PSE533 are remote vacuum sensors with a 1 to 5V analog signal output. 531 is for low vacuum range of -101 to 0 kPa, while PSE533 is for compound pressure from -101 to 101 kPa. PSE sensors can monitor any non-corrosive, non-flammable gas. The accuracy and environmental capabilities are suitable for general purpose applications. The cable is replaceable, with a locking thread relief. PSE531 and PSE533 are CE and RoHS compliant, with IP40 enclosure ratings.
