What Is A Pull Wire Encoder And How Does It Work

With the application of the pull wire displacement sensor is more and more common, it is more and more important to understand the pull wire encoder, because if you do not understand the working principle of the pull wire encoder, you can not really apply the pull wire encoder to the product or equipment.

So how does the drawstring displacement sensor work?

First guy we're going to see the structure of the encoder, as the name implies, it is composed of coder and pull box thread encoder, the encoder is also called the angular displacement sensor, is used to measure the Angle, the output is a square wave signal, a circle of dozens, hundreds, or thousands of pulse number, angular displacement sensors measure the Angle is calculated according to the number of pulses, For example, a circle of output 360 pulses, the calculation method is a week of 360° divided by the pulse number 360p, the resolution of the Angle sensor is 1°/p, and the pulse number reaches 3600, the resolution of the angular displacement sensor becomes 0.1°/p.
Stay encoder is calculated the same way, the encoder mount pull box, then he became the guy encoder, and pull box conversion was linear displacement, displacement of the straight line to how to calculate, is about to see pull box inside the perimeter of the winder, circumference divided by the number of pulses, it is concluded that the resolution of the unit is mm/p, such as the perimeter of the winder is 100, The pulse number of the encoder is 1000p, so the resolution of the drawstring displacement encoder is 0.1mm/p. If the acquisition system has the function of quadrupling frequency, the pulse number becomes 4000p, and the resolution becomes 0.25mm/p.

The principle of the pull wire displacement sensor is to convert the Angle of the angular displacement sensor into a linear displacement using the perimeter of the circuit, so we also call the pull wire encoder for the Linear Displacement Sensor.
