Gefran M30-6-M-P10M-1-4-0 Melt Pressure Transducer 10000 PSI

Product Overview

The Gefran M30-6-M-P10M-1-4-0 2130X000X00, associated with ordering code F008535, is a mercury-filled melt pressure transducer intended for measuring high process pressure in plastics extrusion and similar high-temperature processing equipment. Its 0 to 10,000 psi measuring range is intended for systems whose controller, alarms and mechanical pressure limits are configured for this full-scale value. The transducer provides a low-level 3.33 mV/V strain-gauge signal rather than an amplified current-loop output.

Main Features

• 0 to 10,000 psi pressure range for high-pressure melt applications.
• 3.33 mV/V low-level output for compatible strain-gauge instrumentation.
• Mercury-filled M3 sensing construction.
• Six-pin electrical connection and 1/2-20 UNF process thread.
• Six-inch rigid stem without a flexible capillary section.
• Compact rigid-stem arrangement for installations with suitable clearance and thermal layout.

Technical Specifications

Compatible System and Applications

This transducer can be used with extrusion pressure indicators, controllers and acquisition modules that accept the specified mV/V bridge signal. The receiving instrument must provide the appropriate bridge excitation and must be scaled for a 10,000 psi full range. It should not be connected directly to an input intended only for 4–20 mA transmitters. Typical applications include extruder barrel, adapter and die pressure monitoring where a rigid-stem installation is mechanically and thermally suitable.

Maintenance and Replacement Notes

Before replacement, compare the complete nameplate rather than using only the M30 family designation. Confirm pressure range, output sensitivity, six-pin connector wiring, process thread, rigid-stem length and the absence of a flexible capillary. The mounting hole must be clean and correctly machined; excessive installation torque or hardened polymer at the tip can damage the sensing diaphragm. Controller scaling and alarm settings must be checked when replacing a lower-range transducer.

Related Models

M30-6-M-P05M-1-4-0 F008531 uses the same rigid-stem concept but has a 0 to 5,000 psi range. M31-6-M-P10M-1-4-D F008653 retains the 10,000 psi range while adding a flexible section. W31 models use an FDA-compatible oil filling system instead of mercury. Related models are provided for family reference only and are not automatically interchangeable.

Inquiry and Supply Notes

Please provide photographs of the complete nameplate and connector when requesting this model. F008535, the full model suffix, calibration range, stem construction and equipment input type should be matched before quotation. Availability, condition and calibration documentation must be confirmed for each supply inquiry.
