PREMASREG® 711x - VA(cable gland)The electronic PREMASREG® 711x - VA pressure transducers and switches are equipped with eight switchable measuring ranges, one switching output, one continuous output, and a display for setting the switchpoint and showing the actual pressure (eight devices in one, plus differential pressure switch/monitor, continuous pressure transducer in a single device). The pressure switches feature a V4A stainless steel housing, a cable gland or M12 connector according to DIN EN 61076-2-101 and a stainless steel quick-connect pressure port (pipe fitting optional). They serve to measure positive, negative or differential pressures in clean air, with limit value switching. The piezoresistive measuring element guarantees a high degree of reliability and accuracy. 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. Media measured with these pressure transducers are air (non-precipitating) or other gaseous, non-aggressive, non-combustible media. The pressure sensor device has a button for manual zero-point calibration (automatic zero-point calibration optional) as well as one offset potentiometer for setting the switching point and one for final value correction. The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
