ME Mercury filled – Output 4…20mA

ME

Overview

The ME series of Gefran, are pressure transmitters for use in high-temperature environments and specifically designed for melt pressure measurement and available only to be used in large-scale fixed installations or in large-scale stationary industrial tools, typically extruders, or for laboratory B2B equipment for R&D purposes according to the European Directive 2011/65/EU.

  • The main characteristic of this series is the capability to read the temperature of the media up to 400°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 the strain-gauge technology.
