Introduction

The MN 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 400°C.The constructive principle is based on the hydraulic transmission of the pressure.The fluid-filled system assures the temperature stability.The phisical measure is transformed in a electrical measure by means the strain-gauge technology.
