Product Overview

The Gefran W31-6-M-P05M-1-4-D 2130X000X00, ordering code F021515, is a W3-series melt pressure transducer with an FDA-compatible diathermic-oil filling system. It measures from 0 to 5,000 psi and converts diaphragm pressure into a 3.33 mV/V bridge signal for compatible industrial pressure instrumentation. The combination of a rigid stem and flexible section helps separate the electrical housing from the hottest part of an extrusion or polymer-processing installation.

Main Features

• 0 to 5,000 psi calibrated pressure range.
• W3 oil-filled construction for applications where the filling-medium selection matters.
• 3.33 mV/V output with 0.5% FSO accuracy class.
• Six-inch rigid stem followed by an 18-inch flexible capillary section.
• 1/2-20 UNF process connection and six-pin electrical connector.
• Published W3-series process-temperature capability up to 315°C, subject to installation conditions.

Technical Specifications

Compatible System and Applications

The model is intended for compatible bridge-input pressure indicators and extrusion control systems. Its oil-filled sensing construction may be selected where mercury-filled devices are unsuitable under the user's material, process or regulatory requirements. Filling-fluid suitability must still be evaluated for the actual process; the W3 family designation alone does not establish compliance for every finished machine or application.

Maintenance and Replacement Notes

The flexible section must be routed without sharp bends, crushing or contact with moving machine components. Keep the electronic housing within its permitted ambient conditions and do not use the flexible capillary as a handle during installation. Verify the mounting bore, thread condition and diaphragm seat before tightening. A 5,000 psi controller scale and alarm configuration must be retained unless the control system is deliberately recalibrated.

Related Models

W31-6-M-P10M-1-4-D F021516 has a 10,000 psi range rather than 5,000 psi. M31-6-M-P05M-1-4-D F008650 has comparable nominal range and stem arrangement but uses a mercury-filled M3 sensing system. K31 models use a NaK filling system for a different high-temperature application profile. Related models are provided for family reference only and are not automatically interchangeable.

Inquiry and Supply Notes

Specify F021515 and submit the full nameplate when requesting a quotation. Confirm the W31 prefix, P05M pressure code, D flexible-section code, six-pin connector, output type and required filling medium. Product condition and available documentation should be established separately for each supplied unit.
