Potentiometers and sensors

What is the potentiometer? This so-called resistor adjustable. What does this mean in practice? The potentiometer is there as a separate item and is an adjustable voltage divider. The principle of its action is a classic voltage divider, and its typical application is the adjustment of current or voltage in electrical devices, such as speakers. In the section of the handle you will find a very varied assortment.

Sensors and potentiometers

As we already know, what is the potentiometer, let's see what the sensors are also available in the disk partition. These are devices that convert motion into an electrical signal. Later, this signal is read using a pulse counter or a PLC. Currently, the most widespread and most commonly used optical sensors. They can be divided fundamentally into two groups – incremental or absolute. The first of these give a signal in the form of pulses, the state low or high which indicates the direction of rotation. It lacks the ability to determine the position specifications. The study is only a movement from one position to another.

Absolute encoders

The second type of sensors is an absolute in a position to determine in addition to change of position, from one to another, the indicator of each of them. The most common are incremental sensors. How is the signal in enkoderze? The led emits a beam of light that penetrates through the transparent disc on which are plotted opaque line. Behind the disc is a photo sensor that reads the value of the light signals. In response to the light signals of the photo sensor generates pulses. In turn, the pulses arrive at the counter or the driver, and after counting a certain number of pulses, the execution of programmed actions.
