Draw wire displacement sensor！

Draw wire displacement sensor also known as rope sensors, linear displacement sensors, rope electronic ruler, cable box, rope encoder. Pull rope displacement sensor is a linear displacement sensor in the structure of the sophisticated composition, fully integrated angle sensor and linear displacement sensor advantages to become a small installation size, compact structure, measurement stroke, high precision sensors, travel from one hundred Mm to ten meters.

The function of a pull rope displacement sensor is to convert mechanical movement into electrical signals that can be metered, recorded or transmitted. The Roundss Displacement Sensor consists of a stretchable stainless steel wire wrapped around a threaded hub that is connected to a precision rotation sensor. The sensors can be incremental encoders, absolute encoders, hybrid or conductive plastic rotors Potentiometer, synchronizer or resolver.

In operation, the pull rope displacement sensor is installed in a fixed position and the pull rope is tied to the moving object. The linear motion of the drawstring is aligned with the axis of motion of the moving object. When exercise occurs, the drawstring stretches and contracts. An internal spring ensures that the tension of the drawstring is constant. The threaded hub rotates the precision rotation sensor to output an electrical signal that is proportional to the travel distance of the drawcord. Measuring the output signal gives the displacement, direction or velocity of the moving object.

Commonly used parameters are measured stroke, output signal mode, linearity, repeatability, resolution, diameter specifications, the outlet tension, the maximum round trip speed, weight, input resistance, power, voltage, temperature, vibration, protection class . Signal output method
Pull rope displacement sensor signal output is divided into digital signal output and analog signal output, digital output type can choose incremental rotary encoder, absolute encoder, the output signal is a square wave ABZ signal, cosine signal, CANopen signal, Free RS485 signal, MODBUS signal, Profibus signal or Gray code / Binary signal. It has long measuring distance (100 ~ 15000mm), high precision (~% FS) and IP65 protection. Enclosures and spools are both corrosion-protected and the towline is a 316 stainless steel cord that can work in harsh environments, including seawater. Optional output methods are: resistance type, voltage type, current type, incremental pulse type, absolute pulse type.

Analog output type can choose precision potentiometer, Hall encoder, absolute encoder, the output signal can be 4-20 mA, 0-5 volts, 0-10 volts and resistance signals, the maximum stroke can reach 12500 mm , The use of the environment up to IP65 protection level, -45 ℃ ~ +105 ℃ wide temperature environment.
