Melt Pressure Transducers

High-temperature pressure sensors and transmitters designed for extrusion, fiber, and polymer processing. Includes 1:1 replacements for industry standards and eco-friendly, alloy-filled solutions for the recycling and food industries.


Longvista provides a comprehensive range of melt pressure transducers and transmitters engineered for the demanding environments of plastic, rubber, and synthetic fiber extrusion. Our solutions are designed to ensure process stability, minimize downtime, and meet the highest safety standards.

Whether you need a cost-effective 1:1 industrial replacement, a high-precision digital transmitter with AutoZero, or a mercury-free solution for food and medical applications, our sensors provide the reliability your production line requires.


Which Series is Right for Your Application?

  • MP Series (The Industrial Standard): The ideal choice for Maintenance and Repair (MRO). Designed as a seamless drop-in replacement for Gefran (M Series) and Dynisco (PT Series). Reliable, robust, and cost-efficient.

  • MPES Series (Precision & Automation): Featuring Remote AutoZero and SIL2 certification. Best for high-end automated lines, medical extrusion, and processes requiring digital signal stability and enhanced safety.

  • MPE RoHS Series (Sustainability & High-Temp): Our Mercury-Free (Alloy-Filled) series. Mandatory for food-grade packaging and pharmaceutical extrusion. Capable of operating in extreme environments up to 700°C.


Technical Advantages at a Glance

  • Global Compatibility: Standardized 1/2″-20UNF, M14, and M18 threads.

  • Signal Flexibility: Wide range of outputs including 3.33 mV/V, 4-20mA, and 0-10V.

  • Swiss Quality & Support: Local expertise and fast response times for the DACH and Italian markets.

  • Inconel 718 Diaphragms: Standardized high-durability materials for abrasive and recycled resins.


FAQ

  • Can Longvista sensors replace Gefran and Dynisco models? Yes. Our transducers are designed to be 1:1 interchangeable regarding threads, pinouts, and signal outputs.

  • Do you offer mercury-free sensors? Yes, our MPE RoHS Series uses a non-toxic alloy-fill, making it safe for food and medical applications.

  • What is the lead time for standard sensors? We maintain a local stock in Switzerland for the most common configurations to ensure minimal downtime for our customers.
