Gefran ME1-6-M-B07C-1-4-D Melt Pressure Transmitter 700 Bar

Product Overview

The Gefran ME1-6-M-B07C-1-4-D 2130X000X00, ordering code F007714, is a high-range melt pressure transmitter calibrated from 0 to 700 bar. It is intended for pressure monitoring in extrusion systems where the expected operating and protective limits exceed the capacity of common 350 or 500 bar transmitters. The transmitter supplies a two-wire 4–20 mA signal and requires a compatible 10–30 VDC current loop.

Main Features

• 0 to 700 bar full-scale pressure range.
• 4–20 mA amplified output for PLC and controller integration.
• 0.5% FSO accuracy class with approximately 1 ms response time.
• Mercury-filled hydraulic pressure transfer system.
• Magnetic autozero and 80% full-scale calibration signal.
• Six-pin electrical connector and 1/2-20 UNF process thread.
• Rigid-plus-flexible construction for thermal separation.

Technical Specifications

Compatible System and Applications

This model can serve high-pressure melt locations such as melt-pump discharge, restrictive filtration sections and extrusion dies, provided that the machine design permits a 700 bar measuring range. The control system should interpret 4 mA as zero and 20 mA as 700 bar. Using an incorrectly configured analog scale can conceal an overpressure condition or cause nuisance shutdowns.

Maintenance and Replacement Notes

Before removing the installed transmitter, record the engineering units, full-scale setting, alarm thresholds and shutdown logic. Seven hundred bar is approximately 10,153 psi and is therefore not the same calibration as a 10,000 psi P10M model. Inspect the pressure port for contamination and confirm that the sensing diaphragm will not contact the bottom of the mounting hole. Maintain the flexible section above its minimum safe bend radius and protect the connector from moisture and polymer residue.

Related Models

ME1-6-M-P10M-1-4-D F007744 is calibrated to exactly 10,000 psi rather than 700 bar. ME1-6-M-B05C-1-4-D F007704 is the lower 500 bar version. ME2-6-M-B07C-1-5-D F007779 adds a type J thermocouple and uses a longer rigid-stem code. ME1-6-H-B07C-1-4-D F044832 changes the accuracy class from M to H. Related models are provided for family reference only and are not automatically interchangeable.

Inquiry and Supply Notes

State F007714 and the complete 2130X000X00 model when requesting supply. Confirm the 700 bar calibration, six-pin connector, 4–20 mA output, process thread, mechanical lengths and nameplate condition. Suggested pricing does not establish current inventory or delivery time.
