Product information "Sensor for atmospheric pressure"

The senssor is designed to determine the absolute atmospheric pressure. The outgoin analogue signal can be used for meteorological purposes or as input signal for control and regulation applications. With a piezoresistive pressure sensor and signal conditioning electronic the actual air pressure will be transformed into a compensated, proportional, standardized electrical output. The aluminium die cast metal housing is powder-coated and splash-proof. It will protect the electronic against the influence of the weather and offers good EMC (electromagnetic compatibility) characteristics.
