The electronic
PREMASREG
®
716x
pressure sensor and switch 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 with a housing made from impact-resistant plastic,
with cable gland or M12 connector according to DIN EN 61076-2-101 and pressure connection nozzles (quick connect optional) are fitted with one
switching output, one continuous output and one backlit display for setting the switching point and displaying the ACTUAL values. The piezoresistive
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 filter monitoring and 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. Parameter entry is menu-based and is easy to perform
using three buttons with the help of the display. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible. A
connection set
ASD-06
(2 m connection hose, two pressure nipples, screws) is included in the scope of supply.
