Melt Pressure and Temperature Transducer Applications

Melt Pressure and Temperature Transducer is mainly used in industrial fields that need to measure the pressure of high-temperature and high-pressure melts. Here are some of the main application areas:

Plastics Processing: The Melt Pressure and Temperature Transducer is widely used in the plastics processing industry to monitor melt pressure and temperature in injection molding machines, extruders, and other equipment. This helps ensure stable pressure during plastic molding and improves product quality.
Rubber manufacturing: In the rubber manufacturing process, melt pressure transmitters are used to monitor the pressure changes of rubber at high temperatures, helping to control processes such as rubber extrusion, molding and vulcanization.
Chemical industry: Chemical processes may involve high-temperature and high-pressure fluids, and melt pressure transmitters are used to monitor and control the pressure in chemical reactors, pipeline systems and other equipment.
Pharmaceutical Manufacturing: In some pharmaceutical manufacturing processes, melt pressure and temperature need to be controlled under specific conditions to ensure that the product meets quality standards.
Food Processing: When food is processed in high temperature environments, melt pressure transmitters can be used to monitor and control the pressure of the fluid to ensure safety and consistency during food processing.
High Temperature Liquid Handling: In addition to plastics and rubber, the Melt Pressure and Temperature Transducer can be used for other high temperature liquid handling, such as the melting and processing of metal alloys.

Overall, Melt Pressure and Temperature Transducer plays a key role in various industrial applications that need to handle high-temperature and high-pressure fluids, ensuring the stability, safety and efficiency of the production process.

What is a melt pressure transducer?

The high-temperature melt pressure transducer is an electronic device that can convert physical quantities (pressure) into electrical signals (current, voltage or opening, IO-LINK, HART). The melt pressure transmitter is a pressure/temperature sensing and sensing element that can detect pressures up to 538°C in high temperature environments.

High temperature melt pressure transmitters are based on two main construction technologies (i.e. extended or completely non-liquid silicon). Four different structures are available: rigid rod, flexible sheath, flexible thermocouple, and exposed capillary tube.
