Belimo’s new 22DPD Sensors for Wet-to-Wet Differential Pressure Measurement Utilizing Remote Sensors in HVAC Systems

December 21, 2022
On December 2, Belimo releases new 22PDP-585 and 22PDP-588 active sensors (4…20 mA / 0…5 V / 0…10 V) for wet-to-wet differential pressure measurement utilizing remote sensors in HVAC systems. The sensors are suitable for water and water-glycol mixtures.

The 22PDP reduces installation time and material costs with external sensors by connecting the high and low side sensors at the measurement point. The hinged cover and spring-loaded terminal block save wiring time and ensure reliable contact. The enclosure is NEMA 4X / IP65 rated and offers an LCD.

Simplifies installation, commissioning, and operation
