PREMASGARD® 112x（1125-U）The calibratable, compact pressure sensors PREMASGARD® 112x (series) are equipped with eight switchable measuring ranges and with or without optional display (eight devices in one) and are used for measuring above-atmospheric, below-atmospheric, or differential pressures and volume flow in air. The piezoresistive measuring element is temperature-compensated and guarantees a high degree of reliability and accuracy. The pressure transmitters feature a configurable offset and a button for manual zero adjustment. Applications of these sensor devices are found in cleanroom, medical and filter engineering, in ventilation and air conditioning ducts, in spray booths and large-scale catering facilities, in filter monitoring and level measuring or frequency converter triggering. Media measured with these pressure transducers are air (non-precipitating) or other gaseous, non-aggressive, non-combustible media. The pressure transmitters support eight selectable measuring ranges and therefore minimise the diversity of types and inventory levels while covering a greater range of applications. The differential pressure sensors are supplied including an ASD-06 connection set (2 m connection hose, two pressure connection nipples, screws).
