Gefran ME2-6-M-B05C-1-4-D 2130X000X00 / F007769 Melt Transmitter Type J

Pressure and Temperature Measurement at One Process Point

Gefran ME2-6-M-B05C-1-4-D 2130X000X00, material code F007769, combines a 500 bar melt pressure transmitter with an isolated Type J thermocouple. It is intended for high-temperature polymer and extrusion processes where operators need to compare pressure behavior with the temperature of the material at the same sensor location. The pressure section supplies a two-wire 4–20 mA signal, while the thermocouple supplies a separate low-level temperature signal.

Process Monitoring Value

Simultaneous pressure and temperature information can help distinguish mechanical restrictions from temperature-related viscosity changes. For example, increasing pressure accompanied by falling melt temperature may indicate a different process condition from increasing pressure at stable temperature. Interpretation remains application-dependent and should be based on validated machine limits rather than universal alarm values.

Technical Specifications

Controller and Wiring Requirements

Configure the current input for 0 bar at 4 mA and 500 bar at 20 mA. The temperature input must be configured for Type J and must provide suitable cold-junction compensation. Maintain thermocouple polarity and use wiring practices appropriate for low-level temperature signals. Do not connect thermocouple conductors to the powered pressure loop. Check the manufacturer wiring diagram and mating connector before energizing either channel.

Maintenance and Replacement

Remove the transmitter only after pressure and temperature have reached safe service conditions. Inspect the sensor bore for frozen material, verify the 1/2-20 UNF thread and prevent tools from contacting the diaphragm. During replacement, compare the complete model, F007769 code, pressure range, capillary length and temperature-channel requirement rather than matching only the ME2 series name.

Related Configurations

ME2-6-M-B35D-1-4-D 2130X000X00 (F007783) is the 350 bar version and requires different analog scaling. ME2-6-M-B07C-1-5-D 2130X000X00 (F007779) increases the span to 700 bar and uses a different stem-length code. ME1-6-M-B05C-1-4-D 2130X000X00 (F007704) is a 500 bar pressure-only transmitter without the ME2 Type J channel. Related models are provided for family reference only and are not automatically interchangeable.

Supply Notes

Order using F007769 and the complete model string. Confirm the nameplate, thermocouple type, cable and connector scope, pressure engineering unit, required documentation and product condition for the individual inquiry. No inventory or delivery status is implied by this description.
