How does Linear Encoder Work?

If you have a factory or a mill and want to measure the movement of liner objects, you must avail of a linear encoder to get a better outcome. You can operate the device to run in a different direction, but the travel will always be on one axis. Instead of a linear encoder, people likely use ring encoders. Therefore, to get the maximum workflow, you must avail of the products from sino dro system for more convenience.

Before discussing the liner encoder working process, let’s learn the major parts of the device. The device is built with three basic elements: Scale or Tape, transducer, and single source. These three elements help to detect the linear movement of any object.

The scale is a subject of different lengths because you may use customized tape if the operating object length is more than two to fifty meters or even more. Therefore, the scale is made of stainless steel. A single source helps to detect the pulse of the object and put the mark on the scales. At last, the transducer helps to convert the position information digitally and show the actual position of any object.

How Linear Encoder works

After learning a little about the function of the three major elements, it’s time to discuss the working method of a linear encoder. The device uses two types of measuring methods, incremental and absolute. Therefore, sino dro system is such a name in this industry that provides immense support and quality product.

Incremental method

In this method, the encoders generate pulses per travel unit and count the pulses along with the movement of the load. One disadvantage of using an incremental linear encoder is that the position will be lost if the power supply will lose. A quadrature output is created by the incremental encoding method. The two channels, A and B, monitor the 90-degree angled phase.

Absolute Method

In this method, the encoder gives digital codes unique for each object position. The bits’ number defines the resolution in the absolute linear encoder. The best part is the data will be safe even after a power cut.

The working method of a linear encoder can be divided into two other considerations depending on sensing technology. Optical and magnetic encoders work as per the outer element’s sense. Let’s define it briefly.

Optical encoder

An optical encoder uses a photo-detector and a light source to determine the position of an object. However, using an optical encoder is a risk because dirt and debris can affect the liner movement of the encoder as lightening issues. You must ensure the device is far from any vibration; otherwise, the mounting may be affected.

Magnetic Encoder

A magnetic scale and reader-head are used to detect the position of an object with the magnetic encoder. The device is the best to use in a contaminated position in your factory. Though it’s free from dirt, magnetic chips, like iron or steel, can affect functionality.

Wrapping Up

Conclusively, the working method of linear encoder depends on the type of elements used in it. Therefore, you must consult and avail of the products of sino dro system to get a better performance from the measuring device.
