Sensors Are for Wet-to-wet Differential Pressure Measurement in HVAC Systems 

Belimo has released its 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. 

Model 22PDP-585: Differential Pressure Sensor

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
–    Housing with separate mounting plate for straightforward, easy wall mounting 
–    Remote pressure transmitters eliminate the need for impulse tubes
–    Removable terminal block for efficient wiring 
–    Output signals, pressure ranges, and other configurable options selectable directly from the unit
–    Settings and measurement data are visible
–    Manual zero-point adjustment

Versatile application 
–    Flexible installation with remote pressure transmitters 
–    Various on-site configuration options 
–    Integrated LCD for parametrization and pressure indication 
–    Four selectable pressure ranges within the maximum pressure range
–    Available output signals 4…20 mA, 0…5/10 V
