Gefran KE1-6-M-B01C-1-4-D-S 2130X000X00 Melt Transmitter
Overview
Gefran KE1-6-M-B01C-1-4-D-S 2130X000X00, Gefran code F040926, is the 100 bar member of this KE1 NaK-filled 4–20 mA transmitter group. Its lower full-scale range is intended for melt processes where normal operating pressure is substantially below the levels associated with 350, 500 or 700 bar transmitters. Selecting a range closer to the actual process window can improve the useful resolution of the controller input, but only when adequate allowance remains for startup and transient pressure.
Application-Specific Selection
This model should not be chosen solely to obtain greater display resolution. Review recorded startup peaks, screen-pack loading, cold-material conditions and the machine’s shutdown thresholds before specifying a 100 bar span. The transmitter must not be used as a substitute for mechanical overpressure protection. PLC scaling, high-pressure alarms and recorder ranges must all be changed when migrating from a higher-range model.

Mounting and Commissioning
Install only after the line has been cooled and depressurized. Check that the mounting bore, thread and diaphragm seat correspond to the existing installation. Protect the diaphragm from impact and hardened polymer, maintain a gradual bend radius in the flexible capillary and keep the electronics away from direct heater radiation. Confirm the correct mating connector, wiring diagram, loop polarity and 100 bar controller scaling before startup.
Related Pressure Ranges
KE1-6-M-B35D-1-4-D-S 2130X000X00 (F034502) increases the span to 350 bar. KE1-6-M-B05C-1-4-D-S 2130X000X00 (F046485) is rated for 500 bar. KE1-6-M-P05M-1-4-D-S 2130X000X00 (F049682) uses a 5000 psi order code, while KE1-6-M-P10M-1-4-D-S 2130X000X00 (F036156) is the 10000 psi version. These differences require corresponding changes to control scaling and alarm limits. Related models are provided for family reference only and are not automatically interchangeable.
Inquiry Notes
Provide a clear nameplate photograph when replacing an installed sensor. Confirm F040926, every model character, the 2130X000X00 code, diaphragm suffix, pressure unit, connector, cable requirement and mechanical lengths before ordering.
