Gefran KE1-6-M-P05M-1-4-D-S NaK Melt Pressure Transmitter

Product Overview

The Gefran KE1-6-M-P05M-1-4-D-S 2130X000X00, ordering code F049682, is a NaK-filled melt pressure transmitter calibrated from 0 to 5,000 psi. The KE family uses a near-incompressible sodium-potassium transmission medium and provides an amplified 4–20 mA signal. This exact configuration carries diaphragm code S, identifying a 15-5 PH diaphragm rather than the Inconel 718 or Hastelloy alternatives available elsewhere in the KE family.

Main Features

• 0 to 5,000 psi calibrated pressure range.
• NaK-filled hydraulic transmission system.
• Two-wire 4–20 mA output with 10–30 VDC supply.
• 0.5% FSO accuracy class.
• 15-5 PH diaphragm identified by suffix S.
• Six-inch rigid stem and eighteen-inch flexible section.
• Six-pin connector and 1/2-20 UNF process connection.

Technical Specifications

Compatible System and Applications

This transmitter can be used in polymer extrusion and engineered-material processing where a NaK-filled pressure measurement device is specified. Although the wider KE family includes diaphragm options rated up to 538°C, the S code on this exact model identifies the 15-5 PH version with a published maximum of 400°C. Process compatibility and any food or medical application requirements must be evaluated for the complete machine rather than inferred from the NaK filling medium alone.

Maintenance and Replacement Notes

Confirm that the receiving equipment supports a 4–20 mA loop; a K31 mV/V transducer cannot be exchanged without reviewing the input circuit. Check the S diaphragm code, connector wiring and loop polarity. The mounting bore must match the 1/2-20 UNF geometry, and installation torque must not exceed the applicable manufacturer limit. Do not perform autozero while residual melt pressure remains in the barrel.

Related Models

KE1-6-M-P10M-1-4-D-S F036156 increases the range to 10,000 psi. ME1-6-M-P05M-1-4-D F007742 has the same nominal pressure range and 4–20 mA output but uses mercury filling. K31-6-M-P05M variants provide a low-level mV/V signal instead of 4–20 mA. KE1-6-M-P05M-1-4-D-S-P F071611 is a PLc configuration carrying an additional safety suffix. Related models are provided for family reference only and are not automatically interchangeable.

Inquiry and Supply Notes

Specify F049682 and the complete S-suffix model when requesting a quotation. Verify that the offered unit is not the S-P safety version, an H Hastelloy version or an I Inconel version. Nameplate photographs should confirm pressure range, diaphragm code, output, connector, stem arrangement and component condition.
