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.
