Main promoted products

1. Melt pressure measurement series

A core monitoring component for the melt spinning process of chemical fibers, suitable for mainstream fiber production scenarios such as polyester and polyamide. It can accurately capture the pressure changes of high-temperature fluid at extruders, melt pumps, and spinnerets, feed back data in real time to adjust production parameters, avoid melt blockage or fiber deformation, and ensure the stability of the spinning process and the uniformity of fiber quality.

2. Temperature measurement Series

Focuses on temperature control throughout the chemical fiber production process. It accurately monitors the process temperature in key equipment such as melting furnaces and heat-setting machines, and adjusts the heating system in real time in conjunction with the control system to stabilize the temperature in the core process range. This directly improves fiber strength and performance consistency while helping to optimize production energy consumption.

3. Pressure Measurement Series

Adapts to the pressure monitoring needs of multiple scenarios in chemical fiber production. It collects pressure signals in real time at spinneret boxes, conveying pipelines and other links and converts them into usable electrical signals, providing data support for dynamic pressure regulation. It can match the pressure management needs of different fiber production such as polyester and polyamide, ensuring the smooth progress of the production process.

4. Flow measurement series

Targets the metering needs of chemical fiber solution and solvent conveying links. It accurately monitors fluid flow and dynamically adjusts the conveying speed and dosage in conjunction with the control system, adapting to the rhythm of high-speed spinning production. It ensures the uniformity of fiber diameter and provides process support for the refined production of differential fibers.

5. Displacement measurement series

Used for positioning control of key equipment such as spinnerets and winding heads. It can automatically adapt to the operating status of the equipment, reduce fiber breakage caused by positioning deviations, and form a stable control closed loop in conjunction with the servo system, helping to improve the production efficiency and yield of filament yarns.

6. Differential pressure measurement series

Mainly used in filtration systems and heat exchange equipment in chemical fiber production. It monitors the differential pressure changes between the front and rear ends of the equipment in real time, promptly warns of abnormal situations such as blockage and leakage, ensures production continuity, and provides data reference for the formulation of equipment maintenance plans, reducing the risk of unplanned downtime.

7. Level and liquid level series

Adapts to the liquid level management of chemical fiber raw material storage tanks and cooling liquid circulation systems. It monitors the liquid level height in real time and links with control devices to accurately control the raw material dosage and the liquid level balance of the cooling system. It meets the liquid level control needs of different production scenarios and ensures the standardized and controllable production process.

8. Intelligent Controller series

As a core component for the intellectualization of chemical fiber production, it can link various sensors to build a closed-loop control system, realizing real-time analysis of production parameters, intelligent decision-making, and precise execution. It is suitable for mainstream chemical fiber equipment such as texturing machines and extruders, helping enterprises improve the digital level of production and optimize product qualification rate and production efficiency.
