Ultra low differential pressure sensor for HVAC applications with 4-20mA current loop or amplified voltage output signal in pressure ranges from 0.1 mb up to 1 bar differential.
DPS very low differential pressure transducer is an affordable option for measuring the differential pressure of airflow on heating, cooling, ventilation & air conditioning (HVAC) systems in buildings, laboratories, cleanrooms & factories.
The DPS ultra low differential pressure transmitter can also be used for measuring filter condition and ensuring a differential pressure between two rooms.
For overpressure conditions where there is the risk of a pressure up to 2 bar maximum being applied to either pressure port there is an optional automatic overpressure protection feature that can be specified which uses high frequency valves to isolate the DPS differential air pressure sensor from the system and vent both ports to atmospheric pressure. After a few seconds the valves will re-open very quickly and if an overpressure condition still exists they will quickly close again to protect the sensor.
