Fischer pressure transmitter Building technology DE25

Fischer DE25 Differential pressure transmitter, DE25 is a differential pressure transmitter with a 3-wire electrical interface. It is suitable for accurate measurement of positive / negative gauge pressure or differential pressure of air and gases. The instrument is based on resistive sensor element and can measure positive gauge, negative gauge or differential pressure.
