Differential pressure measurement in air handling unit

The measurement of differential air pressure in air-handling equipment is most often encountered when monitoring the clogging of filters or the operation of fans. There, two-state measurement and evaluation using differential manostats will suffice. In variable air volume systems (VAV) however, the air-handling unit usually has the task of maintaining a constant pressure on the supply, exhaust or between. This requires continuous measurement, which is what differential pressure sensors are used for. When assembling and putting them into operation, it is good to follow a few simple rules, which we will remind you of in the following text.
