Ziasiot PTES melt pressure transducer used in the extrusion production line

With the continuous advancement of intelligent manufacturing in the plastic processing industry, blow molding, extrusion lines, injection molding machines, blow molding machines and other plastic machinery are developing towards high precision, high efficiency and green production. As a key component for real-time monitoring and closed-loop control, the melt pressure transducer directly determines the dimensional stability, surface quality and production safety of plastic products such as pipes, profiles, sheets and films.

 

Against this background, the Ziasiot PTES series melt pressure transducer, with its eco-friendly design, high temperature resistance and high compatibility, has been widely used in extrusion production lines and has become an ideal alternative to traditional sensors.

 

 

In modern plastic processing, melt pressure detection has become an indispensable link.

 

In the extrusion production process, the quality standards of products, including dimensional accuracy and surface flatness, require optimized control of extrusion pressure. By installing melt pressure transducers at the mold inlet and combining them with pressure control systems, manufacturers can achieve stable pressure output, effectively reduce material waste, improve product consistency, and extend the service life of screws and molds.

 

In actual production, unstable melt pressure often leads to dimensional deviation, poor surface finish, high reject rate and even equipment damage. Therefore, high-performance melt pressure transducers have become core components for enterprises to improve quality and reduce costs.

 

 

Since 2016, Ziasiot has been committed to the R&D and promotion of eco-friendly high-temperature melt pressure sensors. After more than two years of research, the company launched a mercury-free eco-friendly high-temperature melt pressure transducer with national invention patent, which has passed RoHS and CE certifications.

 

The PTES series melt pressure transducer (mV/V, mA, or V) – SIL2-certified-rigid stem+flex+temperature J/ E/ K/PT100 plug optional offers a melt pressure measurement range from 0 to 20000 psi with accuracy up to 0.25% and a process temperature up to 400℃,  and is perfect for harsh and rugged working conditions in plastic processing. It adopts mercury-free alloy filling, which is non-toxic, non-flammable and environmentally safe. At the same time, it can be used as an equivalent replacement for Gefran and Dynisco, supporting direct installation without modifying the equipment or wiring.

 

 

In actual on-site applications, Ziasiot PTES melt pressure transducers are installed at the feed section and mold inlet of extrusion lines.

 

They monitor melt pressure in real time, feed signals back to the control system, and realize closed-loop pressure regulation. This effectively improves the dimensional accuracy and surface flatness of extruded products, reduces material waste and unplanned downtime, and enhances overall production safety and environmental compliance.
