In modern industrial production, high-temperature melt pressure sensors play a critical role in measuring and controlling the pressure of high-temperature melts, fluids, and gaseous media. These sensors are widely utilized across various fields, including chemical fiber spinning, polyester rubber, plastic extrusion machinery, nonwoven fabric production, and the manufacturing of construction and packaging materials.
Definition and Working Principle
A high-temperature melt pressure sensor (commonly abbreviated as HTMPS) is a specialized electronic device designed to measure the pressure of molten substances under high-temperature conditions. The sensor operates based on the principles of either piezoresistive or piezoelectric effects.
When the pressure from the medium being measured directly acts on the sensor’s diaphragm, the diaphragm undergoes microdisplacement proportional to the medium’s pressure. This displacement causes changes in the sensor’s resistance or electrical charge. The device then processes these changes through electronic circuits, converting them into standard signals such as voltage or current, enabling accurate pressure measurement.
