Gefran ME1-6-M-P10M-1-4-D Melt Pressure Transducer

The Gefran ME1-6-M-P10M-1-4-D is a mercury-filled melt pressure transducer from the ME series, featuring an amplified 4–20 mA output signal. This transmitter-level output distinguishes the ME from the mV/V output M3 series, allowing the ME to connect directly to PLCs, indicators, and data acquisition systems without requiring an external signal amplifier.

The ME series is engineered for melt pressure measurement in high-temperature industrial environments and is designed for use in large-scale fixed installations and stationary industrial equipment such as extruders and laboratory R&D equipment, in accordance with European Directive 2011/65/EU. The sensor can handle process media temperatures up to 400°C.

The operating principle relies on hydraulic pressure transmission through a mercury-filled system, which ensures thermal stability of the output signal across the full temperature range. The physical pressure is converted to an electrical signal using strain gauge technology in a Wheatstone bridge configuration.

An internally generated 80% calibration signal (R-Cal) enables in-situ verification of transducer performance without removing the sensor from the barrel. The standard diaphragm is 15-5 PH stainless steel with Gefran’s GTP+ protective coating. A corrugated 17-7 PH diaphragm with GTP+ coating is available for pressure ranges below 100 bar (1,500 psi). Standard thread options include 1/2-20 UNF and M18×1.5, with additional types on request. The 6-pin connector version carries IP65 protection.
