HWX4 Diathermic oil FDA flanged – HART – ATEX – SIL2 – PLd

HWX4

Overview

  • The HWX4 series of Gefran, are pressure transmitters for use in High-temperature environments and specifically designed for melt pressure measurement and available to be used in large-scale fixed installations or in large-scale stationary industrial tools rather than laboratory equipment.
  • The HWX4 series of Gefran is flanged 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.
  • The SIL2 and PL d approvals make the product suitable for use in the Functional Safety applications, particularly in the process plants for the production of polymers, where it is an essential requirement.
