with active output (U/I switchable) and 4 measuring ranges (max. 600...1100 hPa, switchable), in a
compact plastic housing with quick-locking screws, optionally with/without display. The pressure sensor is used for measuring atmospheric air
pressure in clean air (non-precipitating) or other non-aggressive, non-combustible gases. It is used in various applications such as ventilation and air
conditioning technology, in meteorological measurement stations and air-pressure-dependent control systems. The piezoresistive measuring element
is temperature-compensated and guarantees a high degree of reliability and accuracy. The sensor is factory-calibrated; an environmental precision
adjustment by an expert is possible.
