HWX

Overview

  • The HWX series of Gefran are pressure transmitters with HART communication protocol for use in high-temperature environments with explosive atmosphere presence.
  • The main characteristic of this series is the capability to read the temperature of the media up to 315°C.
  • The constructive principle is based on the hydraulic transmission of the pressure.
  • The fluid-filled system assures temperature stability.
  • The physical measure is transformed into an electrical measure by means of strain-gauge technology.
