The electronic pressure sensors and switches PREMASREG® 711x are equipped with eight switchable measuring ranges, one switching output and one continuous output, and a display for setting the switchpoint and to display the ACTUAL pressure (eight devices in one plus differential pressure switch ⁄ differential pressure monitor and continuous pressure sensor in a single device). The pressure sensor is used for above-atmospheric, below-atmospheric, or differential pressure measurement in clean air with limit value switching. The piezo-resistive measuring element guarantees a high degree of reliability and accuracy. Applications of these pressure sensors are in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray booths, in large-scale catering facilities, for monitoring filters, for level measurement or for triggering frequency converters. Media measured with these pressure transducers are air (non-precipitating), or other gaseous non-aggressive, non-combustible media. The pressure sensor has a manual zero point pushbutton and an offset potentiometer for final value and switchpoint correction. Fine adjustment by the user is possible at any time. A connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws) is included in the scope of supply.
