The 631B series liquid differential pressure transmitters can accurately monitor the differential pressure of air as well as compatible liquids or gases. They output a standard 4-20mA signal on a two-wire loop. The front panel has digital buttons, making it easy to calibrate zero and span. The 631 series transmitters have a protection rating of NEMA 4X (IP66), a rugged structure, can withstand up to 500 psi, and can measure differential pressures as low as 0.5 inches of water.
