DFL
Pressure and differential pressure transducer, with active output and 8 switchable measuring ranges
Application
The DFL is a differential pressure transducer and is used to measure overpressure, underpressure or differential pressure in the air. The digital sensor (MEMS) guarantees high reliability and accuracy. These pressure sensors are used in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray cabins, in commercial kitchens, for purposes of filter monitoring and fill level measurement or to control frequency inverters. The measured medium is air (non-condensing) or gaseous, non-aggressive, non-combustible media.
