Gefran ME Melt Pressure Transmitters

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

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

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.

Product Overview The Gefran ME1-6-M-B07C-1-4-D 2130X000X00, ordering code F007714, is a high-range melt pressure transmitter calibrated from 0 to 700 bar. It is intended for pressure monitoring in extrusion systems where the expected operating and protective limits exceed the capacity of common 350 or 500 bar transmitters. The transmitter supplies a two-wire 4–20 mA signal and requires a compatible 10–30 VDC current loop. Main Features 0 to 700 bar full-scale pressure range.

Product Overview The Gefran ME1-6-M-B35D-1-4-D 2130X000X00, ordering code F007725, is a mercury-filled melt pressure transmitter calibrated from 0 to 350 bar. It converts melt pressure into an amplified two-wire 4–20 mA signal for extrusion controllers, PLC analog inputs and process monitoring systems. This configuration uses a 1/2-20 UNF process connection, a six-inch rigid stem and an eighteen-inch flexible section, allowing the electronic housing to be positioned away from

Product Overview The Gefran ME1-6-M-P10M-1-4-D 2130X000X00, ordering code F007744, is a 4–20 mA melt pressure transmitter calibrated from 0 to 10,000 psi. It is intended for high-range extrusion and polymer-processing pressure monitoring where an amplified current signal is transmitted to a PLC, indicator or process controller. The 10,000 psi calibration is a defining characteristic of this model and must agree with the machine's displayed range, alarm thresholds and

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

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

Product Overview The Gefran ME1-6-M-B05C-1-4-D 2130X000X00, ordering code F007704, is a 500 bar mercury-filled melt pressure transmitter for continuous pressure measurement in polymer extrusion equipment. Its amplified 4–20 mA output can transmit the process signal to a PLC or pressure controller over longer cable runs than a low-level mV/V bridge signal. The B05C calibration is intended for machines requiring a metric 500 bar full-scale value. Main Features Metric pressure

Product Overview The Gefran ME1-6-M-P05M-1-4-D 2130X000X00, ordering code F007742, is an amplified melt pressure transmitter with a 0 to 5,000 psi measuring range and 4–20 mA output. It is designed for extrusion and polymer-processing control systems that receive an industrial current-loop signal. Unlike a passive mV/V transducer, the ME1 contains signal-conditioning electronics, so power supply, loop wiring, input loading and polarity must be checked as part of the

Pressure and Temperature Measurement Configuration The Gefran ME2-6-M-B07C-1-4-D-000 is a mercury-filled melt pressure transmitter configured for simultaneous process pressure measurement and type J thermocouple temperature feedback. It provides a 4–20 mA pressure signal and is designed for high-temperature polymer processing installations. This exact configuration is documented with a 700 bar full-scale pressure range, 153 mm rigid stem and 457 mm flexible capillary. These
