Barometers/ Measuring transducers for atmospheric pressure PREMASGARD® ALD
Calibratable PREMASGARD® ALD barometre 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 transmitter serves to measur the 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 systems, 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 and can be fine-tuned to ambient conditions by an expert.
