MPES Series: Precision AutoZero Melt Pressure Transmitters
The MPES Series represents the next generation of melt pressure monitoring, combining high-precision digital circuitry with a convenient remote AutoZero function. Designed for processes where signal drift is not an option—such as medical-grade tubing, fine fiber spinning, and high-end sheet extrusion—the MPES provides superior linearity and stability. With SIL2 compliance and CE certification, it is the professional choice for safety-critical and high-accuracy polymer processing.

Description
Precision for Modern Extrusion Lines
Intelligence at the Point of Pressure Unlike standard analog sensors, the MPES Series utilizes an advanced digital circuit design. This allows for real-time linear compensation, ensuring that the pressure signal remains accurate even as the machine’s thermal conditions change. The “AutoZero” feature is a game-changer for modern automated factories: it allows the operator to reset the sensor’s baseline pressure from the control room when the pipeline is at temperature but zero pressure.
Ideal for High-End Polymer Processing Whether you are manufacturing composite films or high-precision pipes, the MPES Series ensures that your “shot-to-shot” consistency is maintained. By reducing signal noise and drift, it provides the clean data required for high-speed automated control systems.

FAQ
-
How does the Remote AutoZero work? When the system is at the correct temperature but zero pressure, you simply short pins D and F on the connector for 2-3 seconds. The transmitter will then calibrate itself to zero.
-
Is the MPES Series suitable for the food or pharmaceutical industry? Yes, we offer versions with specific diaphragm materials and mercury-free fillings suitable for sensitive environments.
-
What does SIL2 certification mean for my plant? SIL2 (Safety Integrity Level 2) indicates that the sensor meets strict reliability standards for use in safety-instrumented systems, reducing the risk of process failure.
