Gefran KE1-6-M-B05C-1-4-D-S 2130X000X00 Melt Transmitter
| Place of Origin | USA |
| Brand Name | Gefran |
| Model Number | KE1-6-M-B05C-1-4-D-S 2130X000X00 |
Product Identity and Function
Gefran KE1-6-M-B05C-1-4-D-S 2130X000X00 is a 500 bar NaK-filled melt pressure transmitter with Gefran material code F046485. It converts pressure acting on the high-temperature process diaphragm into a two-wire 4–20 mA signal. Typical uses include extrusion lines, polymer processing equipment and machinery where the electronic housing must be separated from the hottest measurement point by a rigid stem and flexible capillary.
Control-System Scaling
The B05C code specifies a 0–500 bar measuring span, also associated with the nominal 7500 psi class. A controller configured for the 350 bar B35D version will display an incorrect pressure when connected to this transmitter, even though the electrical signal format is the same. During commissioning, configure 4 mA as 0 bar and 20 mA as 500 bar, then verify the engineering unit used by alarms, trends and shutdown logic.

Replacement Checks
Do not select this unit only because another KE1 transmitter has the same connector or 4–20 mA output. Confirm the existing process thread, pressure span, stem lengths, diaphragm option and full 2130X000X00 code. Before installation, clean the sensor bore with an appropriate maintenance tool and make sure no frozen process material can contact or side-load the diaphragm. Verify loop polarity and grounding before applying power.
Range Alternatives
KE1-6-M-B35D-1-4-D-S 2130X000X00 (F034502) is the 350 bar version and can provide finer usable resolution where the process remains below that limit. KE1-6-M-B01C-1-4-D-S 2130X000X00 (F040926) covers 100 bar. KE1-6-M-P10M-1-4-D-S 2130X000X00 (F036156) is a 10000 psi configuration. Safety-certified, external-autozero and alternative diaphragm suffixes represent separate configurations. Related models are provided for family reference only and are not automatically interchangeable.
Ordering Information
Request the product using both F046485 and the complete model. Supply status, calibration documentation, cable inclusion and product condition must be confirmed for the individual quotation rather than inferred from the series designation.
