What Is a Melt Pressure Transducer?

A Melt Pressure Transducer is a high-temperature pressure sensor used to measure molten polymer pressure in extrusion and injection molding machines. It features a robust diaphragm designed for continuous service near heaters and barrels, delivering stable signals to PLC/SCADA systems for precise control of throughput, thickness, and quality.

How it works

• High-temperature diaphragm detects melt pressure and converts it to an electrical signal.
• Conditioned outputs include 4–20mA, 0–10V, and mV/V.
• Standard 1/2-20UNF process connection fits most extrusion heads.
• Integrates with Pressure Sensors and temperature control for closed-loop performance.

• Zero and span with 10–24V supply; verify output at ambient and operating temperature.
• Route cables away from heaters; use shielded wiring for electrical noise immunity.
• Integrate outputs (4–20mA or 0–10V) to PLC/SCADA for alarms and control loops.
• Schedule periodic checks to ensure Melt Pressure Transducer accuracy and process stability.

Selection Guide: Choosing the Right Melt Pressure Transducer

Use this quick guide to select a Melt Pressure Transducer that matches your extrusion or molding application. As a Melt Pressure Transducer manufacturer, we help size and configure sensors for accuracy, lifetime, and easy integration.

• Pressure range: Choose a range that covers normal operation plus safety margin (e.g., 0–350 Bar to 0–2000 Bar).
• Temperature rating: Verify diaphragm rating up to 400°C for high-heat zones near the die head.
• Output type: Pick 4–20mA or 0–10V for PLCs; use mV/V for legacy amplifiers; HART for diagnostics.
• Process connection: Standard 1/2-20UNF fits most extruders; confirm thread length and tip style.
• Stem and cable: Select rigid/flexible stem lengths to avoid heater interference and allow proper routing.
• Compliance: Request calibration docs and QA certificates for audits and regulated environments.

Maintenance and Troubleshooting

Proper maintenance extends the lifetime of your Melt Pressure Transducer and keeps measurements stable under high temperatures and mechanical stress.

• Inspect threads and seating surfaces at changeovers; avoid overtightening beyond 40 N·m.
• Keep tips free from hardened polymer; use approved cleaning methods to protect the diaphragm.
• Check zero/span at ambient and operating temperature; record drift for predictive maintenance.
• Route cables away from heaters and VFDs; use shielding and proper grounding to reduce noise.
• Schedule periodic calibration—contact us for service on your Melt Pressure Transducer.
