Senses the pressure of air and compatible gases, this differential pressure transmitter features a pressure range of ±30 Pa and has a 4 to 20 mA output. Fast and easy to set up, this transmitter is suitable for fan control, static pressures in ducts or buildings, room pressurization monitoring, and differential pressure across filters.

Fast and easy to set up, this transmitter is suitable for fan control, static pressures in ducts or buildings, room pressurization monitoring, and differential pressure across filters.
Specifically designed to mount in a standard Magnehelic® gauge cutout, this pressure transmitter features a polycarbonate molded housing with integral pressure connections, reducing installation time. In addition, the digital push-button zero and span simplify calibration over typical turn-potentiometers, and a single push-button allows field selection of multiple engineering units.
