Gefran ME1-6-M-B05C-1-4-D Melt Pressure Transmitter 500 Bar

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 range from 0 to 500 bar.
• Two-wire 4–20 mA output for industrial analog inputs.
• 10–30 VDC operating supply.
• 0.5% FSO accuracy class.
• Mercury-filled pressure transmission system for melt applications.
• 153 mm rigid stem and 457 mm flexible section.
• 80% full-scale R-Cal signal for checking controller scaling.

Technical Specifications

Compatible System and Applications

The 500 bar range is appropriate for extrusion processes whose normal operating window and protective limits are configured below this full scale. It can be used for monitoring pressure before or after a screen changer, at a melt pump inlet or outlet, or near an extrusion die. The connected PLC channel must support a powered two-wire current loop and the permitted load must be matched to the selected supply voltage.

Maintenance and Replacement Notes

A 500 bar transmitter must not be treated as a 7,500 psi transmitter merely because the nominal values are close. Five hundred bar is approximately 7,252 psi, so the controller span, displayed units, alarm limits and recorded process data will differ. After installation, verify the zero condition and use the calibration function only according to the applicable operating procedure. Do not use the flexible capillary to rotate or tighten the process connection.

ME1-6-M-B35D-1-4-D F007725 has a lower 350 bar range. ME1-6-M-B07C-1-4-D F007714 extends the range to 700 bar. ME1 P75C versions are calibrated to 7,500 psi rather than 500 bar. ME2-6-M-B05C-1-4-D F007769 incorporates a thermocouple and belongs to the pressure-and-temperature configuration group. Related models are provided for family reference only and are not automatically interchangeable.

Inquiry and Supply Notes

Use F007704 together with the complete model when requesting a quotation. Verify that the supplied item carries the B05C range code and 2130X000X00 configuration. Photographs should clearly show the pressure range, output, connector, stem construction and all nameplate suffixes.
