Digital Barotransmitter

Indicating measurement instrument with analogue output to determine the atmospheric pressure. An aneroid capsule with inductive displacement pickup serves as a sensor. The sensor signal is amplified electronically and displayed on a LC display. The analogue output is available for the connection of electronic recording and control instruments. Behind the removable front panel there is a potentiometer to reduce the measured value to sea level. The instrument is in the form of a switch cabinet for panel installation.
