PREMASGARD
The calibratable pressure sensors PREMASGARD
V4A housing, optionally with ⁄ without display, with cable gland or M12 connector according to DIN EN 61076-2-101 and pressure port by stainless
steel quick connection (pipe fitting optional) are used 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 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 filter monitoring and 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 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; an environmental precision adjustment by an expert is possible.
