Pressure, differential pressure and volume flow measuring transducers PREMASGARD® 212x
The calibratable compact pressure transmitters of the PREMASGARD® 212x series are equipped with 8 switchable measuring ranges, 2 switchable output signals (16 devices in one) and with/without optional display. They 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.
These pressure measuring transducers have a pushbutton for manual zero-point calibration and an adjustable offset. Applications 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. Media measured with these pressure transducers are air (non-precipitating) or other gaseous, non-aggressive, non-combustible media. The differential pressure sensors are supplied including an ASD-06 connection set (2 m connection hose, two pressure connection nipples, screws).
