Mercury-Free Melt Pressure Transmitters | RoHS & 700°C High-Temp | MPE Series
MPE RoHS Series Mercury-Free & Ultra High-Temp Melt Pressure Transducer
The MPE Series provides safe, high-performance pressure measurement for sensitive extrusion environments, including food contact packaging, medical tubing, and extreme thermal processing. Engineered with an eco-friendly, non-toxic alloy filling instead of standard mercury, the MPE Series complies fully with RoHS standards while operating reliably at continuous diaphragm temperatures up to 700°C.
Key Highlights:
-
100% Mercury-Free Fill: Features a proprietary non-toxic alloy medium, ideal for food, pharmaceutical, and medical packaging extrusion.
-
Extreme Thermal Resistance: Withstands continuous process diaphragm temperatures up to 700°C.
-
RoHS Compliant & Patented: Designed to meet international environmental regulations and industrial safety standards.
-
Rugged Environment Protection: IP65 safety grade housing shields internal components from dust and water ingress in harsh washdown areas.
Description
Safe, Non-Toxic Pressure Monitoring for Eco-Conscious Extrusion
The MPE Series Mercury-Free Melt Pressure Transducer is designed specifically for manufacturers who must comply with strict environmental policies and food/pharma safety directives. Traditional melt pressure sensors rely on mercury as a hydraulic transmission fluid, creating potential contamination risks during diaphragm failure. The MPE Series replaces mercury with an advanced, non-toxic alloy fill, ensuring zero risk of toxic contamination in food packaging, medical grade polymers, and eco-friendly plastic production.
Superior Thermal Performance: Up to 700°C
Beyond environmental safety, the MPE Series excels in extreme-temperature extrusion applications where standard sensors fail. Featuring a patented thermal barrier and high-durability alloy fluid line, the diaphragm tolerates continuous process temperatures up to 700°C without sacrificing measurement integrity.
Enclosed in an IP65-rated housing, the MPE Series delivers dependable pressure telemetry in hostile industrial environments subject to moisture, chemical exposure, and elevated ambient heat.

FAQ
Q1: Why should I choose a mercury-free melt pressure transducer like the MPE Series? A: Mercury-free transducers eliminate the danger of process contamination. If a diaphragm ruptures on a standard sensor, toxic mercury can leak into your extrusion batch. The MPE Series uses a non-toxic alloy fill, making it essential for food packaging, medical tubing, cosmetics, and RoHS-compliant manufacturing facilities.
Q2: Can the MPE Series handle higher temperatures than standard melt pressure sensors? A: Yes. While standard mercury-filled sensors are typically limited to 400°C, the MPE Series is rated for extreme continuous process temperatures up to 700°C at the diaphragm, making it suitable for high-temperature engineering plastics and specialized thermal processes.
Q3: Is the MPE Series a direct physical fit for existing standard mounting holes? A: Yes. The MPE Series utilizes standard industrial thread sizes (such as 1/2-20 UNF and M18x1.5) and industry-standard electrical pinouts, allowing you to upgrade your machine to mercury-free technology without modifying your extruder barrel.
Q4: What is the difference between the MPE Series and the MP or MPES Series? A: The MPE Series is specifically designed for mercury-free compliance, food/pharma safety, and extreme heat environments up to 700°C. The MP Series is our standard economy model for general industrial extrusion up to 400°C, while the MPES Series is designed for applications requiring digital remote AutoZero and SIL2 safety compliance.
