Product Preview

Focusing on precise temperature control throughout the entire PET polyester production process, our products are customized for key equipment such as PET polymerization reactors, melting furnaces, spinning boxes, heat setting machines and drying towers.They can stably monitor process temperatures in high-temperature and high-humidity industrial environments of 200-300℃, and adjust the heating system in real time in coordination with the control system. It accurately locks the core process temperature range of PET esterification, polycondensation and spinning, directly improving the consistency of key performances including PET chip viscosity, fiber strength and preform transparency. Meanwhile, it optimizes production energy consumption and meets the development needs of the PET industry for ecologicalization and high efficiency.

As a key monitoring component for the core processes of PET polyester melting, polycondensation, spinning and extrusion granulation, it is perfectly adapted to the full-range production scenarios of PET chips, bottle preforms, polyester filament and staple fiber.It can capture real-time changes in high-temperature melt pressure of PET at the discharge port of polymerization reactor, extruder barrel, melt pump and spinneret, and feed back data to the control system quickly to dynamically adjust production parameters.It avoids common problems in polyester production such as melt blockage, degradation, carbonization and fiber deformation from the source, ensuring stable PET production technology and uniform product quality. It serves as an essential supporting component for PET enterprises to improve yield rate, reduce raw material loss and control production costs.

It precisely meets the multi-scenario pressure monitoring demands throughout the entire PET polyester production process, fully covering key production links such as internal pressure of PET polymerization reactors, spinning box cavity pressure, raw material pipeline pressure, gas storage system pressure, and injection molding holding pressure.It collects pressure signals in real time and converts them into standard electrical signals, providing accurate data support for dynamic pressure regulation during production. Flexibly adaptable to pressure management requirements for manufacturing PET chips, bottle preforms, fibers and other product types, it effectively prevents overpressure leakage, unstable feeding and equipment damage, ensuring the stable operation of continuous and large-scale PET polyester production.

Designed for the conveying and metering demands of key media in PET polyester production, including PTA slurry, ethylene glycol, PET melt, modified additives and cooling water, it perfectly adapts to the fast-paced production mode of high-speed spinning and continuous polymerization.It monitors the flow rate of various fluids in real time and dynamically adjusts the conveying speed and medium dosage in linkage with the control system, ensuring accurate proportioning of PET raw materials and stable and uniform melt transportation.It provides core process guarantee for the refined production of functional PET and differentiated PET fibers such as superfine denier and antibacterial fibers. As an essential supporting component, it helps PET manufacturers upgrade production equipment, realize energy saving and consumption reduction, and enhance product added value.

Adapted to liquid level and material level management scenarios across the entire PET polyester production process, it covers key equipment such as PET raw material storage tanks, PTA silos, ethylene glycol storage tanks, cooling water circulation systems and dosing tanks for additives.It monitors liquid and material levels in real time and links up with control devices to accurately control the feeding amount of PET raw materials, maintain the balance of cooling liquid level and ensure the precise proportioning of additives.It perfectly meets the core requirements of precision batching and standardized management in large-scale and continuous PET production, effectively avoiding downtime due to material shortage and waste caused by overflow. It standardizes and streamlines the PET production process while reducing operational and maintenance costs.

As a core component for the intelligent and digital upgrading of PET polyester production, it can seamlessly link with various sensors of our product series to build a closed-loop control system covering the entire PET production process, including polymerization, spinning, injection molding and forming.

It enables real-time collection, analysis, intelligent decision-making and precise execution of production parameters, and is widely compatible with mainstream PET production equipment such as spinning machines, extruders, injection molding machines and polymerization reactors. It helps PET enterprises elevate the digital and intelligent level of production, improve product qualification rate and production efficiency, and fully aligns with the high-end and intelligent development theme of this Polyester Industry Summit.

Widely applied to core components such as the positioning of PET spinning spinnerets, tension displacement of winding heads, roller positioning of drawing machines, and precise mold opening/closing control of injection molding machines. It automatically adapts to high-speed equipment operation, corrects positioning deviations in real time, and effectively reduces quality issues caused by mechanical displacement, including broken filaments, yarn hairiness, dimensional deviation of bottle preforms and uneven wall thickness. Working with the servo system to form a stable closed-loop control, it helps PET manufacturers improve filament production efficiency and product qualification rate, while ensuring continuous and stable production.

Focusing on the key auxiliary links in PET polyester production, it is mainly applied to core parts such as filtration systems, heat exchange equipment and melt conveying pipelines to monitor differential pressure changes at the front and rear ends of equipment in real time.It can give early warnings of abnormalities including filter blockage, pipeline scaling and equipment leakage, effectively avoiding the risk of unplanned downtime. It provides accurate data reference for formulating equipment maintenance plans, ensures the continuous production of PET polyester, reduces equipment operation and maintenance costs, helps enterprises improve overall production efficiency and cut production losses.

Made of high-quality materials with high temperature resistance, wear resistance and corrosion resistance, it is precisely suitable for scenarios such as PET polyester raw material weighing, stress monitoring of production equipment components and spinning tension control. It maintains stable and high-precision measurement in PET production industrial environments with wide temperature fluctuations, high dust and high viscosity.

It provides reliable data support for accurate metering of PET raw material feeding, evaluation of equipment operation status and stable control of spinning tension. It helps PET enterprises realize refined management of production processes, improve product quality stability between batches, and meet the production requirements of high-end PET products.
