Gefran KE1-6-M-P10M-1-4-D-S NaK Melt Pressure Transmitter

Product Overview

The Gefran KE1-6-M-P10M-1-4-D-S 2130X000X00, ordering code F036156, is a NaK-filled melt pressure transmitter with a 0 to 10,000 psi calibrated range. It is intended for high-pressure polymer-processing locations requiring an amplified 4–20 mA signal and a sodium-potassium pressure transmission medium. The exact S diaphragm code identifies the 15-5 PH contact diaphragm configuration with a published maximum diaphragm temperature of 400°C.

Main Features

• 0 to 10,000 psi high-pressure calibration.
• Near-incompressible NaK filling medium.
• Two-wire 4–20 mA industrial output.
• 10–30 VDC power requirement.
• 0.5% FSO accuracy class with approximately 1 ms response.
• 15-5 PH contact diaphragm with GTP+ protection.
• Six-pin connector and rigid-plus-flexible mechanical construction.

Technical Specifications

Compatible System and Applications

This configuration is intended for high-pressure extrusion zones such as melt-pump discharge, fine filtration assemblies and restrictive die systems. The connected controller must be scaled for exactly 10,000 psi. A 700 bar transmitter is close in nominal capacity but produces a different pressure interpretation throughout the 4–20 mA span. Alarm, trip and machine-protection values must therefore be reviewed whenever the calibration code changes.

Maintenance and Replacement Notes

Before replacement, verify loop supply voltage, allowable load, polarity and connector pin assignment. Inspect the flexible stem for kinks and ensure that it has not been used to apply installation torque. The process port should be cleaned only with appropriate tools and without scraping the sensing diaphragm. Autozero is permitted only at zero pressure. Record the existing shutdown values before changing the transmitter or controller scale.

Related Models

KE1-6-M-P05M-1-4-D-S F049682 has a 5,000 psi range. ME1-6-M-P10M-1-4-D F007744 provides a 10,000 psi 4–20 mA signal but uses a mercury-filled system. K31 P10M variants use an mV/V bridge output. KE1-6-M-P10M-1-4-D-S-E adds the external autozero option, while S-P and S-S configurations belong to different safety versions and require certification review. Related models are provided for family reference only and are not automatically interchangeable.

Inquiry and Supply Notes

Request the product using both F036156 and the complete model. Confirm that the required configuration ends with D-S and does not carry an additional E, P or S suffix. The pressure range, diaphragm material, loop output, connector, stem lengths, certification markings and physical condition must be verified from the offered unit.
