描述
Application
Differential pressure transmitters are used for acquiring the differential pressure of air in ventilation, air conditioning, and heating plants, which measures the pressure of air and nonaggressive gases with great accuracy and no offset drift. It can measure over- or under-pressure in air ducts in relation to ambient pressure as well as to monitor filters and to control fans and acquire pressure difference between different rooms. It can be widely applied to Air-conditioning and ventilation systems, Building automation, Environmental protection, Fan and ventilation control, Valve and shutter control, Filter and fan monitoring.
