On July 12, 2024, the "2024 Spandex Industry New Quality Productivity Development Forum", sponsored by China Chemical Fiber Industry Association and undertaken by Spandex Branch, was held as scheduled in Luoyang, Henan Province. Graeff (Jiaxing) Instrument Co., Ltd. participated in the forum and became a member of China Chemical Fiber Industry Association.

    China Chemical Fiber Association, which is an important communication bridge between the government and the industry, maintains the healthy and orderly development of the industry.

    A pair of seemingly ordinary gloves, light and soft, can withstand the intense impact of mechanical cutting; recycled mineral water bottles can be crushed, granulated, melted, and processed into elegant evening gowns... The variety of extraordinary fiber products is dazzling.

    High-temperature melt pressure sensors are used for pressure measurement and control in high-temperature fluid media in equipment such as chemical fiber spinning, polyester, and rubber and plastic machinery. Melt spinning is one of the primary forming methods for chemical fibers, commonly abbreviated as melt spinning. The main types of synthetic fibers include polyester, nylon, and polypropylene.

    The working principle of the melt pressure sensor is that the pressure of the medium directly acts on the sensor's diaphragm, causing the diaphragm to undergo a micro-displacement proportional to the medium pressure. This displacement causes a change in the sensor's resistance, which is detected by electronic circuits and converted into a standard signal corresponding to the pressure.

    GRAEFF (Graff) melt pressure sensors are critical components for monitoring melt pressure. On chemical fiber production lines, GRAEFF (Graff) melt pressure sensors are primarily installed at locations such as melt filters, booster pumps, melt pipelines, screws, and spinning boxes.

     The GRAEFF (Graff) melt pressure sensor is designed to meet every requirement of chemical fiber production, offering customers different melt pressure sensors with high-temperature resistance up to 540°C for various applications. The product features a wide measurement range and high precision. The GRAEFF (Graff) melt pressure sensor plays a crucial role in improving melt quality, enhancing production safety, protecting production equipment, and extending its service life.
