DPT50 WM High-Precision Differential Pressure Transmitter

Model: DPT50 WM / DPT100 WM / DPH100 WM

Differential pressure transmitters of the DPT50 series are designed for building automation in the HVAC/R sector, for monitoring air filters, fans and air flow based on pressure. Ranges and units are set through a USB interface. The DPH100 WM version also measures temperature and relative humidity (T: -30 to 80 °C, RH: 0–100 %).

Accuracy 0.25 % / 0.5 % of FS
Configuration via USB interface
4–20 mA (standard), 0–10 V (optional) and RS485 Modbus RTU
