Gefran ME2-6-M-B07C-1-4-D-000 700 Bar Melt Transmitter

Pressure and Temperature Measurement Configuration

The Gefran ME2-6-M-B07C-1-4-D-000 is a mercury-filled melt pressure transmitter configured for simultaneous process pressure measurement and type J thermocouple temperature feedback. It provides a 4–20 mA pressure signal and is designed for high-temperature polymer processing installations.

This exact configuration is documented with a 700 bar full-scale pressure range, 153 mm rigid stem and 457 mm flexible capillary. These dimensional features are central to replacement selection because they determine the installed position of the sensing electronics relative to the heated process connection.

Model-Specific Technical Specifications

Installation-Critical Dimensions

The 6-inch rigid stem and 18-inch capillary must be verified physically before replacement. A transmitter with the same 700 bar range but different stem or capillary dimensions may not place the electronic housing in a safe location. The capillary must not be sharply bent, twisted or used to support the housing.

Inspect the 1/2-20 UNF mounting hole for damaged threads and hardened process material. Installation depth and sealing geometry must match the existing machine. Excessive torque or contact with the diaphragm can permanently damage the transmitter.

Separate Pressure and Temperature Circuits

The 4–20 mA pressure loop and type J thermocouple circuit perform different functions and must be wired according to the correct terminal diagram. Verify loop polarity, supply voltage, shield grounding, thermocouple polarity and cold-junction compensation. Do not connect the thermocouple input as part of the current loop.

Differences from Related ME Products

ME1-6-M-B05C-1-4-D 2130X000X00 F007704 uses a different pressure code and physical configuration. ME0 variants may use rigid-stem-only construction. WE transmitters use diathermic oil filling, while KE products use sodium-potassium filling. A third-party MPI suffix denotes a compatible replacement rather than this Gefran model.

Related models are provided for family reference only and are not automatically interchangeable.

Maintenance and Replacement Notes

Verify the complete model, 700 bar calibration, type J thermocouple, connector, thread and both length dimensions. Preserve the calibration certificate when available. Do not clean the diaphragm with abrasive or pointed tools.

Inquiry and Supply Notes

Provide nameplate, connector, stem and diaphragm photographs with the inquiry. Suggested internal-link anchor text is “Gefran ME2 700 Bar Melt Pressure and Temperature Transmitter.” Availability and calibration status must be confirmed separately.
