Rope sensor working principle and common parameters:

Rope displacement sensor function is to convert mechanical motion can be measured, recorded or transmitted signals. Rope displacement sensor consists of a stretchable stainless steel wire wound on a threaded hub, round hub and a precision rotary sensors are connected together, the sensor can be incremental encoders, absolute (independent) encoder, or mixed conductive plastic rotary potentiometers, synchronous or resolver.

Operation, rope displacement sensor is mounted in a fixed position on the rope tied to a moving object. Rope linear motion and moving objects movement axis aligned. When movement occurs, the rope stretch and contraction. An internal spring to ensure constant tension of the rope. Threaded hub driven precision rotary sensor is rotated, the output of a rope moving distance proportional to the electrical signal. Measuring the output signal can be obtained displacement, velocity or direction of a moving object.

Common parameters are measured stroke, the output signal mode, linearity, repeatability, resolution, size diameter, and outlet tension, maximum round-trip speed, weight, input resistance, power, voltage, temperature, vibration, degree of protection, etc. .

Signal output:

Rope displacement sensor output signal into a digital signal output and analog output, digital output type can be selected incremental rotary encoder, absolute value encoder, the output signal is a square wave signal ABZ or Gray code signal, can do the maximum stroke to 10000 mm, maximum 0.01% linearity, resolution depending on the configuration can be up to 0.001 mm / pulse.

Analog output type can be selected precision potentiometers, Hall encoder, BEN encoder output signal can be 4-20 mA, 0-5 V, 0-10 V, serial SSI and resistance signals, the maximum possible stroke 12500 mm, maximum use of the environment can achieve IP65 protection rating, a wide temperature environment of -45 ℃ ~ + 105 ℃ use.
