Premasgard 1115-I (vh 1112) 4...20mA + / -5000 Pa, Pressure and differential transmitter with switchable measuring range

The calibratable pressure sensors PREMASGARD~ 1115 with eight switchable measuring ranges and optional display, serve to measure over-, under- or differential pressure in air. The pi~zoresistive measuring element is temperature-compensated and guarantees high reliability and accuracy. The pressure transmitter features a push button for manual zeroing and an adjustable offset. It is used, among other things, in clean rooms, medical, and filter technology, air ducts, spray booths and commercial kitchens, for filter monitoring and full-scale measurement or for controlling frequency converters. The measuring medium is air (non-condensing) or gaseous, non-aggressive, non-flammable media. The differential pressure sensor includes connection set ASD-06 (2 m connecting hose, two pressure connection nipples, screws).
