W7 SIL2

Main features & Overview

Overview

The W7 series of Gefran, are pressure transmitters for using in High temperature environment. The main characteristic of this series is the capability to read temperature of the media up to 315°C. The constructive principle is based on the hydraulic trasmission of the pressure. The fluid-filled system assures the temperature stability. The phisical quantity is transformed  in a electrical measure by means the thick film strain-gauge technology. The SIL2 certified version makes the product  suitable  for use in the Functional Safety applications, particularly in the process plants for the production of polymers, where it is an assential requirement.
