The draw-wire displacement sensor is also called a draw-wire sensor, a draw-wire electronic ruler, or a draw-wire encoder. The draw-wire displacement sensor is a sophisticated structural construction of a linear displacement sensor. It fully combines the advantages of an angle sensor and a linear displacement sensor to become a sensor with a small installation size, compact structure, large measuring stroke, and high accuracy. The stroke ranges from hundreds of millimeters to tens of meters. A draw-wire sensor (also called a string pot, cable extension transducer）is a linear position sensor that measures the displacement or velocity of a moving object. It works by converting the linear motion of a flexible measuring wire into a rotary motion, which is then translated into an electrical signal.

Linear displacement sensor is used to measure the displacement change of an object or structure on a linear axis. Its main uses include: 1.Industrial automation: The linear displacement sensor can be used for automatic control on industrial production lines, such as measuring the position of workpieces on mechanical arms, conveyor belts or machine tools, so as to carry out accurate and stable control.

Pulling-rope displacement sensor is widely used in hydraulic universal testing machine. Its main function is to measure the cylinder stroke of the testing machine, and send it to the controller by pulse signal during the test, so as to obtain the elongation of the tested material. If traditional scale or manual measurement is used, it will not only be inefficient, but also fail to achieve the measured test accuracy. However, the pulling rope displacement sensor has the characteristics of high accuracy of 0.01%, fast response speed, low cost and convenient installation. Compared with grating ruler and other products, it not only improves the displacement accuracy of testing machine, but also reduces the cost of the whole machine.

Pressure sensors are widely used in hydropower generation, railway transportation, intelligent building, production automation, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.

Pulling rope displacement sensor is a precision device that measures displacement by stretching and retracting the rope, widely used in industrial automation, mechanical manufacturing and other fields. The core principles, application scenarios, and usage methods are as follows:

The pull rope displacement sensor is especially suitable for linear guide rail system, hydraulic cylinder system, testing machine, telescopic system (forklift, press, elevator, pipe bender, bender, etc.), crane or cable winch, reservoir dam protection system, gate opening control system, testing machine pressure machinery, hydraulic universal experimental machinery, storage position positioning, pressure machinery, paper-making machinery, textile machinery, sheet metal machinery, packaging machinery, printing machinery. Construction machinery, horizontal controller, construction machinery, industrial robot, injection machine, woodworking machinery, elevator, air compressor/hydraulic press, height machine, X-Y axis and other length displacement, etc., dimension measurement and position control, especially suitable for the control of electro-hydraulic servo hydraulic universal testing machine.

From October 21st to 24th, 2025, the SOP team will participate in Electronics Show 2025 in Korea, and Tina and Jenny, as representatives of SOP Group, will attend the Electronics Show in Korea.

The SOP team is about to participate in the Hanover Industrial Exhibition in Germany in March 2025.

Amidst the busy work pace, our company organized a significant team building activity, which was held in Qili Ancient Town, Ganzhou, Jiangxi. This was not only an opportunity to relax, but also an important moment to enhance team cohesion and collaboration spirit.

Hydroelectric power generation is a complex process. In order to generate stable current, the water turbine must rely on a stable water flow rate. Among them, the linear displacement sensor plays a decisive role in controlling the water flow rate. Water turbines equipped with linear displacement sensors can ensure the sustainable development of hydraulic power by selecting water sources with beautiful environments, water level differences, and sustainable blowouts. There are several very important requirements for choosing a linear displacement position sensor here:

Our company organized a significant team building activity from November 2, 2024 to November 4, 2024. The three-day company team building activity allowed us to enter Hunan Province, Guangdong Province, and finally return to Jiangxi Province. This activity not only enhanced understanding and trust among colleagues, but also made me deeply appreciate the importance of teamwork. As a member of Jiangxi SOP Precision Intelligent Manufacturing Technology Co., Ltd., I would like to share with you our team building activity!
