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.

Draw wire sensor is also called rope ruler and rope encoder. Its working principle is very simple, that is, the wire rope at the outlet of the sensor is pulled, in which the wire rope is wound on a pulley built in the sensor. When the wire rope is pulled, the other end of the sensor is connected to the mechanical motion, and a display is installed on it to convert the mechanical motion into an electrical signal to obtain the required data. In operation, the pull rope displacement sensor is installed at a fixed position, and the pull rope is tied to the moving object. The linear motion of the pull rope is aligned with the motion axis of the moving object. When the movement occurs, the rope stretches and contracts. An internal spring ensures that the tension of the pull rope is constant. The threaded hub drives the precision rotation sensor to rotate, and outputs an electrical signal proportional to the moving distance of the pull rope. The displacement, direction or velocity of the moving object can be obtained by measuring the output signal. Commonly used parameters include measuring stroke, output signal mode, linearity, repeatability, resolution, wire diameter specification, outlet tension, maximum round-trip speed, weight, input resistance, power, working voltage, working temperature, vibration, protection level, etc.

Rope displacement sensor, also known as rope sensor, rope electronic ruler and rope encoder, is a kind of sensor used to measure linear position. It combines the advantages of angle sensor and linear displacement sensor, and has the characteristics of small installation size, compact structure, large measuring stroke and high precision, ranging from hundreds of millimeters to tens of meters. Measuring the opening of the gate: the pull-rope/linear displacement sensor can directly measure the displacement of the gate leaf or arm, thus indirectly reflecting the opening of the gate.

A little carelessness in product selection will lead to poor measurement accuracy or unavailability. Therefore, it is necessary to understand the meaning of the rope displacement sensor when selecting the model, and then purchase it, so as not to cause unnecessary trouble. Here, we will summarize the matters needing attention in the product selection process of the cable displacement sensor:

The steel wire rope of the on-site rope position sensor broke. In response to this situation, the displacement sensor manufacturer has compiled the causes and consequences of the broken steel wire rope of the rope displacement sensor. They hope that in the selection process, customers can avoid detours and reduce cost losses. The main reasons for wire rope breakage in rope displacement sensors are as follows:

The rope displacement sensor has the advantages of wide measurement range, high resolution, good repeatability, and strong anti-interference ability.

JiangXi SOP Precision Intelligent Manufacturing Technology Co., Ltd. has recently launched several new rope displacement sensors: WPS-T-RS485 WPS-T50、WPS-ST80， These three types of rope displacement sensors can all support customization; The general range can reach 1000mm or above, and can support current output, voltage output, resistance output, analog encoder 4-20mA, digital communication, etc. The core component of SOP rope displacement sensor potentiometer, has the characteristics of strong stability, high precision, and long service life (up to 5 million cycles). The diameter of the steel wire rope can reach 0.7mm, and there are hundreds of steel wires inside the rope.

Because of its unique product characteristics, the draw wire transducer is widely used in many fields, such as machinery manufacturing, construction engineering, aerospace, automation control and so on.
