What are the advantages and disadvantages of cable displacement encoders

The wire-drawing displacement encoder is a kind of wire-drawing displacement sensor commonly used by us. Because it is composed of an encoder and a set of wire-drawing devices, we often say that it is a wire-drawing displacement encoder. The wire-drawing displacement encoder is a digital output type of wire drawing. Displacement sensor, what are the advantages and disadvantages of the digital output cable displacement sensor? Follow the editor of okplazas.com to find out.

1 The output of the rope displacement encoder is a digital signal, which is often referred to as a pulse signal. The rope displacement encoder memorizes the displacement of the object by outputting the number of pulses, so that after a power failure, the encoder cannot have any movement; When the call is working, the encoder should not lose the pulse due to interference during the output pulse, otherwise, the zero point of the counting device will be offset, and the amount of this offset is unknown, only the wrong production result appears To know later.

2 There is also an absolute value signal for the rope displacement encoder. The advantage of this signal is that it is not affected by power failure or interference and the uniqueness of each position determined by the mechanical position. It does not need to be memorized, and there is no need to find a reference point. And there is no need to count all the time, when you need to know the position, when to read its position. In this way, the anti-interference characteristics of the encoder and the reliability of the data are greatly improved.

3 The accuracy of the rope displacement encoder is relatively high, and its resolution is optional. There are many options.

4 The rope displacement encoder can be used in a wide range, as long as it is a collection system that can collect digital signals.
