Industrial Encoders and Their Purpose

The precision of industrial equipment are ensured with the use of digital encoders which are industrial and mechanical in nature converting angular cycles of these equipments thereby avoiding disturbance of the performance of the machine. Encoders now come in the forms of absolute and incremental mode, unlike before when binary encoders were used to convert angular and rotation information into binary code.

Digital encoders come in its common kind such as optical encoders, magnetic shaft or rotary encoders, and the metric incremental encoder.

The absolute position, instead of the incremental changes, is reported by the absolute encoders about the position of the shafts in an industrial machinery. With the encoder following a 32-bit counter, a microcontroller then converts the position of the images that are transferred to a device that receives the image. A PC interface is not necessary with the use of optical rotational encoders that assure of smooth running of applications.

Unlike the absolute encoders that produce one output, the incremental encoders using mechanical or optical system, produce two outputs called the mechanical and optical outputs. Examples of incremental encoders are car stereos that normally use this system in order to operate the volume of the car speakers. This type of encoders use two sensors to achieve precision and it comes available with up to 10,000 counts per turn.

Robotics, photographic lenses, gates, valves and other industrial equipments practically use any of all of these wire draw encoder. To ensure smooth, work of the equipment, accuracy and precision in rotations important for industrial equipment, encoders are necessary to deliver the high performance of the machine.

With the use of rotary encoder or shaft encoder, the angle at which a shaft is positioned is translated into digital code thereby making the computer understand, and this is why this type of system is used in robotics, industrial controls and other electro-mechanical devices. With this system, industrial devices are more accurate in their performance, like the flood gates and telescopes.

There are two kinds of shaft encoders in the field of industrial engineering adn these are the absolute and incremental. The difference between the two kinds lie in the fact that the absolute encoders can create a distinct digital code for one axle, while the incremental rotary code has both a mechanical or optical outputs.

To enumerate, mechanical or optical encoders are exemplified in wireless industrial encoders, express encoders, omni encoders, linear transducers, heavy duty encoders, and linear quadrature encoders.

It is undeniable to attribute the importance of digital rotary encoders in the industry because they assure the operation of equipment in a precise manner and because of the security in the running of operations in industries.
