The electronic pressure sensor and switch PREMASREG® 716x is equipped with measuring functions for volume flow, differential pressure, filter monitoring and liquid level detection based on pressure measurement in clean air. The devices are fitted with one switching output, one continuous output and one backlit display for setting the switchpoint and displaying the ACTUAL values. The piezo-resistive measuring element guarantees a high degree of reliability and accuracy.
This pressure sensor is used 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. The medium measured is air (non-precipitating), or other gaseous non-aggressive, non-combustible media. It has a manual zero point pushbutton and an offset potentiometer for final value correction. Fine adjustment by the user is possible at any time. Parameter entry is menu-based and is easy to perform using three buttons with the help of the display. A connection set ASD-06 (2 m connection hose, two pressure nipples, screws) is included in the scope of supply.
