PREMasgard 7115-I VAQ

PREMASGARD® PREMasgard 7115-I VAQ

Item No. 2004-6191-2100-011

The calibratable pressure sensors PREMASGARD® 711x (series) with eight switchable measuring ranges (eight devices in one), housing made from impact-resistant plastic or stainless steel V4A housing, optionally with/ without display, with cable fitting or bushing for M12 connector according to DIN EN 61076-2-101 and with metal pressure port nozzles (quick connect 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 delivery includes the connection set ASD-06 (2 m connection hose, two pressure port nipples, screws).
