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.

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.
