Brand
€162.97
Tax included

The calibratable, compact pressure measuring transducers of the PREMASGARD® 111x series support eight switchable measuring ranges (eight devices in one), arew available with or without optional display and serve to measure above-atmospheric, below-atmospheric or differential pressures as well as 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 are found in cleanroom, medical and filter engineering, in ventilation and air conditioning ducts, in spray booths and in large-scale catering facilities, in filter monitoring and level measuring or frequency converter triggering.
