Gefran F034502 KE1-6-M-B35D-1-4-D-S 2130X000X00 Melt Transmitter
Product Overview
Gefran KE1-6-M-B35D-1-4-D-S 2130X000X00, identified by Gefran code F034502, is a KE-series melt pressure transmitter for pressure measurement in heated polymer, extrusion and high-temperature process equipment. It uses sodium-potassium alloy, or NaK, as the hydraulic pressure-transfer medium and provides a two-wire 4–20 mA signal for connection to a compatible PLC, process controller or indicator.
Why This 350 Bar Configuration Matters
The B35D pressure code identifies the 0–350 bar configuration, corresponding to the nominal 5000 psi class. This range is commonly selected when normal process pressure requires more headroom than a 100 or 200 bar transmitter but does not justify the reduced resolution associated with a 500 or 700 bar range. The receiving channel must still be scaled from 4 mA at zero pressure to 20 mA at 350 bar.

Installation and Loop Configuration
Depressurize and cool the process before removal. Inspect the mounting hole for hardened polymer, damaged threads or an incorrect seat, and do not apply installation force to the sensing diaphragm. Route the flexible section away from sharp bends, moving machinery and concentrated radiant heat. Confirm loop polarity, supply voltage, cable shielding and the exact 6-pin wiring diagram before energizing the transmitter.
Related Models and Selection Differences
KE1-6-M-B05C-1-4-D-S 2130X000X00 (F046485) increases the range to 500 bar. KE1-6-M-B01C-1-4-D-S 2130X000X00 (F040926) is the 100 bar configuration. KE1-6-M-P05M-1-4-D-S 2130X000X00 (F049682) uses a psi-based 5000 psi order code, while KE1-6-M-P10M-1-4-D-S 2130X000X00 (F036156) is rated for 10000 psi. Even where nominal ranges appear similar, the complete nameplate code and controller scaling must match. Related models are provided for family reference only and are not automatically interchangeable.
Inquiry and Supply Notes
Specify F034502 together with the complete model and suffix. Confirm the pressure unit, diaphragm option, process thread, rigid and flexible lengths, connector, existing cable and required product condition before quotation. Availability, production status and delivery time require separate confirmation.
