The ME series of Gefran, are pressure transmitters for using in High temperature environment 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 equipments for R&D purposes according to the European Directive 2011/65/EU (see informative note RoHS II).

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 trasmission 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.

• Pressure ranges from: 0-35 to 0-2000 bar / 0-500 to 0-30000 psi
• Strain gage Wheatstone bridge
• Accuracy : <±0.25% FS (H); <±0.5% FS (M)
• Internally generated 80% calibration signal (R-Cal)
• Fluid-filled system for temperature stability
