Pressure and differential pressure measuring transducers PREMASGARD® 711x-VA
The calibratable pressure transmitters of the PREMASGARD® 711x - VA series feature eight switchable measuring ranges (eight devices in one), a V4A stainless steel housing, optionally with/without display, with cable gland or M12 connector according to DIN EN 61076-2-101 and a stainless steel quick-connect pressure port (pipe fitting optional). The sensor devices serve to measure positive, negative or differential pressures in air. The piezoresistive measuring element is temperature-compensated and guarantees a high degree of reliability and accuracy.

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 pressure sensor devices have a button for manual zero-point calibration (automatic zero-point calibration optional, standard for 25 Pa) and an offset potentiometer for final value correction. The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
