Pressure, differential pressure and volume flow measuring transducers PREMASGARD® 112x

Brand
€162.97
Tax included

The calibratable, compact pressure sensors PREMASGARD® 112x (series) are equipped with eight switchable measuring ranges and with or without optional display (eight devices in one) and are used for measuring above-atmospheric, below-atmospheric, or differential pressures and volume flow in air. The piezoresistive measuring element is temperature-compensated and guarantees a high degree of reliability and accuracy.

The pressure transmitters feature a configurable offset and a button for manual zero adjustment. Applications of these sensor devices are found in cleanroom, medical and filter engineering, in ventilation and air conditioning ducts, in spray booths and large-scale catering facilities, in filter monitoring and level measuring or frequency converter triggering.
