Technical (Project) introduction

The high-temperature melt pressure sensor specifically designed for textile equipment launched by GRAEFF is the culmination of its technological innovation in the field of pressure sensing. This product is specially designed for chemical fiber spinning systems. It can monitor the melt pressure changes at key nodes such as melt filters, booster pumps, and screws in real time. Through high-precision measurements of 0.5%FSO and 0.25%FSO, it optimizes melt fluidity and avoids equipment overload, significantly improving the dimensional accuracy and surface quality of products such as polyester and nylon.

Technological innovation points

(1) Al intelligent temperature drift compensation technology: By using AI algorithms to correct the zero drift problem in high-temperature (350°C-1200°C) environments in real time, it ensures the consistency of multi-sensor collaborative operation and solves the industry problem of accuracy decline of traditional sensors under extreme temperatures.

(2) Environmentally friendly alloy filling technology: Utilizing NTX mercury-free patented alloy liquid to replace traditional mercury media, it has passed FDA certification, meeting hygiene standards in the food, medical and other industries, while reducing temperature drift.

(3) Intelligent integration and Internet of Things applications: Supports seamless connection with PLC/DCS systems to achieve dynamic adjustment of process parameters, and provides remote monitoring and predictive maintenance functions through the cloud platform, promoting the intelligent upgrade of textile production.

Application fields and effects

GRAEFF's high-temperature melt pressure sensors for textile equipment are mainly applied in high-temperature melt spinning processes such as fiber production and nonwoven fabric manufacturing in the textile industry.
