Melt Pressure Transducer, High Temperature Pressure Sensor
Model: PT111
Insulated by rigid or flex tube
Application:

High-temperature pressure sensor is designed for monitoring pressure in molten materials like plastics and polymers.

• High-temperature resistance: Melt pressure transducers are built to withstand process temperatures up to 538°C or higher.
• Robust construction: A specialized diaphragm, often protected by a special coating, protects the sensitive internal sensor from the abrasive and corrosive properties of molten materials.
• Integrated temperature measurement: Some melt pressure transducers include a built-in thermocouple for simultaneous pressure and temperature monitoring.
• Different configurations: They are available in various designs, including rigid stem, flexible sheath, and exposed capillary, to suit different mounting requirements.
• Piezoresistive working principle: Many melt pressure transducers use a piezoresistive strain gauge combined with a fluid-filled system to transmit pressure to the sensor element. Some versions are fluid-free using silicon-based technology.
