Smart Hart Mercury Filled Mel.T. Pressure Transmitters
The HME series of Gefran are pressure transmitters with HART communication protocol for using in high temperature environment. The main characteristic of this series is the capability to read temperature of the media up to 400°C.The constructive principle is based on the hydraulic trasmission of the pressure.The fluid-filled system assures the temperature stability.The physical measure is transformed in a electrical measure by means of strain-gauge technology.
