Pressure, differential pressure and volume flow measuring transducers PREMASGARD 2121 LCD

€217.22
Tax included

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.
