GEMP Series Medium-free Eco-friendly Melt Pressure Sensor

Developed by Dr. Wu Hao’s team through 24 months of intensive research and development, the GRAEFF GEMP Series Medium-free Eco-friendly Melt Pressure Sensor adopts an innovative medium-free design with cutting-edge NFM technology, breaking through the technical bottlenecks of traditional melt measurement. Enduring extreme temperatures of up to 400°C, the sensor enables integrated synchronous detection of pressure and temperature, completely avoiding medium leakage, melt contamination and temperature drift, featuring stable performance and eco-friendly durability. Customized for melt processing and material safety scenarios, it can accurately monitor melt parameters in polymerization melting, stock solution transportation and other processes to ensure stable quality control. Widely applied in food, medical, packaging, polymer and special chemical industries, it delivers high-precision and eco-friendly sensing solutions for the aramid industry and high-end manufacturing sectors.

Relying on this core NFM filling-free medium technology, the company has completed the application for an invention patent, which has been officially accepted by the National Intellectual Property Administration of China (CNIPA). The Official Acceptance Notice for Patent Application titled A High-temperature Melt Pressure Sensor Based on NFM Filling-free Materials was issued on June 03, 2026, with application number: 202610787494.5.The complete set of patent documents includes 9 core claims, full technical specifications, attached drawings and a Request for Substantive Examination, all of which passed the formal examination at one time.

Core Explanation of Patent Acceptance

1. The filing date secures innovation priority right

The filing date of this patent is June 03, 2026. From this date onward, the prior innovation ownership of the NFM filling-free high-temperature sensing technology is officially confirmed. It effectively prevents plagiarism of similar homogeneous technologies worldwide and builds exclusive technical barriers. An invention patent enjoys a statutory protection term of 20 years, fully guaranteeing the long-term exclusive right to use the core self-developed technologies of the GEMP series.

2. Acceptance means the technology enters the statutory examination procedure

Patent acceptance does not equal patent grant. It only indicates that the National Intellectual Property Administration of China (CNIPA) has verified all application documents are complete and compliant, and formally incorporated the application into the invention patent examination process. Since a Request for Substantive Examination was submitted concurrently, examiners will subsequently search global prior art and conduct in-depth verification of the novelty, inventiveness and practical applicability of the NFM filling-free structure. An invention patent right will be granted upon passing all examinations.

3. Mutual empowerment of patents and products drives industrial innovation

This invention patent fully covers underlying innovations of the GEMP series, including the core NFM filling-free medium structure, high-temperature anti-drift structure, and simultaneous pressure-temperature detection solution. Winning the Aramid Industry Technical Innovation Product Award this time serves as dual recognition from the market and the industry of the industrialization value of this patented technology. The patent achievements have been translated into mature mass-produced products, forming a closed loop of technology R&D, intellectual property protection and industrial application.
