The function of differential pressure sensor
Author:
The differential pressure switch is mainly used for system fault alarm, as it can only read one switch quantity, unlike sensors that can read analog quantities
When the pressure difference of the filter screen of the air conditioning fresh air unit exceeds a set value, the pressure difference switch acts and the system alarms, reminding you to clean the filter screen. There are also many centrifugal water pumps equipped with pressure difference switches. If the pressure difference is lower than a set value, an alarm is needed to prevent cavitation of the water pump impeller. The main function of the pressure sensor is to control, and the data read out is input through integral conversion, with the same control performance, Control. Pressure sensors are generally installed in the supply air duct.
