The DER pressure gauge, models 22364 and 22365 are designed for continuous conversion of excess or vacuum pressure into a unified AC output signal based on a change in mutual inductance. The measured media can be liquids and gases that are non-aggressive with respect to the materials of the parts in contact with the measured medium and specified in the passport. The devices are used for operation in explosion-proof rooms. DER manometers are used in stationary conditions (on stationary objects) to operate in a set with secondary devices and various information receivers capable of receiving a standard signal in the form of mutual inductance. This property of interchangeability provides the possibility of joint operation of a secondary device with several devices with periodic connection of measurement points, as well as a quick replacement of a failed device without calibrating the set. The measured medium of the MED-22364 and MED-22365 transducers can be liquid and gas, which are non-aggressive with respect to the materials of the parts in contact with the measured medium and indicated in the passport.
