PREMASGARD
Maintenance-free pressure measuring transducer PREMASGARD
housing with quick-locking screws, optionally with ⁄ without display, nozzles for pressure hose (Ø 6 mm), incl. connection set ASD-06 (2m connecting hose,
two pressure port nipples, screws). The on-wall sensor is used to measure positive, negative or differential pressure in clean air (non-precipitating) or
gaseous, non-aggressive, non-combustible media. It is used in the clean room, medical and filter technology, ventilation and air conditioning ducts, spray
booths, large-scale catering facilities, for filter monitoring and level measurement or for triggering frequency converters. The piezoresistive measuring ele-
ment is temperature-compensated and guarantees a high degree of reliability and accuracy. Innovative Modbus sensor with galvanically separated RS485-
Modbus-interface, selectable bus termination resistance, DIP switch for setting the bus parameters and bus address in current-free state, LEDs for tele-
gram status display, two separate push-in terminals and large three-line display (illuminated; with customised programming in the 7-segment and dot-matrix
range). The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
