EVU-F2AF30D14

Rotary Potentiometers, Rheostats

EVU-F2AF30D14 is a type of Rotary Potentiometer or Rheostat typically used to measure angular displacement. It is an electronically controlled three terminal variable resistor with a resistance track formed in a circular configuration. It is characterized by its small size and ability to measure one millionth of a rotation.

Rotary Potentiometers function by providing a variable resistor that can be moved through a certain range of motion. Rheostats are devices that allow for the adjustment of an electrical current using a two terminal resistor.

The mechanism of the EVU-F2AF30D14 works by the resistance track of the component being divided into smaller sections. The sections are then arranged in a circular or helical pattern. The rotation of the shaft will then cause the resistance track to cover a certain small section at a time, thus allowing for a more precise measurement of rotation.

The main application fields of the EVU-F2AF30D14 include angle measurement equipment, wind speed measurement, antenna direction measurement, navigation systems, and automotive steering systems. It is ideal for rotating shafts that require precise measurement of angular motion and displacement.

In order for the EVU-F2AF30D14 to work properly, it relies on the concept of a negative feedback loop. This allows for a feedback signal to be sent from the potentiometer back to the main control unit. This allows the control unit to detect any change in the potentiometer\'s resistance value and then adjust the output accordingly.

The principle of operation of the EVU-F2AF30D14 is relatively simple. As the shaft on the component rotates, it turns the contact or wiper in the same direction, thus causing the resistance track to cover the same small sections. As the resistance track is covered, the resistance value changes which then creates a voltage difference. The voltage difference is then detected by the control unit and a corresponding output signal is used to adjust the device.

The EVU-F2AF30D14 is a reliable and accurate rotary potentiometer that is simple to operate and maintain. It is suited for applications that require precise measurement of angular motion and displacement. It utilizes the concept of a negative feedback loop to provide very accurate results with minimal effort.
