Differential pressure sensor
PCT/DPT series
product description
Differential pressure sensors are the latest generation of micropressure measurement products. It adopts high-precision ceramic substrate micro differential pressure sensor, advanced MEMS technology to ensure that the sensor indicators are the best compensation method, the lowest range can be up to 25Pa, it can output voltage/current signal at the same time, can be widely used in indoor and outdoor, air duct differential pressure and wind speed measurement.
It is used in ventilation and air conditioning equipment for the following purposes:
Gets the difference between the positive or negative pressure value and the ambient pressure
Filter/filter monitoring
Inverter fan control
VAV system control
Positive and negative pressure monitoring inside and outside the room
