PMM330 Differential Pressure Transmitter (Indoor)

Featuring a hot-wire type differential pressure sensor, this device offers high sensitivity at low pressures, with a minimum measurable value of 1 Pa and low zero-point drift. It supports a differential pressure range of ±50 to ±1500 Pa and can withstand up to 1 bar of pressure. Compact and easy to install, it includes a square root function for air velocity conversion, analog output, and an optional RS-485 communication function. A DIP switch allows for easy range adjustments and square root function activation.
