Rotary Potentiometers,Rheostats

Rotary Potentiometers and Rheostats, commonly referred to as "potentiometer" or "pot", are resistive devices. They are widely used in electrical engineering as components of various electromechanical switches and instruments and in other areas as well.

The PTV142B20E120AA204 is a rotary potentiometer that combines the features of both Potentiometers and Rheostats. It is used in applications that require both precise control of the resistive element and accurate measurement of resistance.

The PTV142B20E120AA204 pot features a 12-bit resolution, with incremental steps as small as 0.5mm, allowing for extremely precise control and measurement.

It also has an internal temperature monitoring module, which can detect temperature changes and adjust the resistance accordingly. This helps ensure the accuracy of the measurements, even in high temperature environments.

The PTV142B20E120AA204 pot is primarily used in industrial automation, control systems, and any other applications where precise control and accurate measurements of a resistive element are needed.

The working principle of the PTV142B20E120AA204 is based on the principle of resistive heating. When a voltage is applied across the resistive element, a temperature gradient results, which causes the resistive element to heat up.

The temperature of the resistive element then changes the resistance value of the element, which in turn causes a change in the output voltage of the pot. The output voltage can then be used to control or measure the resistance of the resistive element.

The temperature monitoring module helps compensate for any changes in the temperature of the resistive element, thus ensuring that the output voltage remains the same and that the measurements remain accurate.

The PTV142B20E120AA204 is a highly versatile and reliable rotary potentiometer, and is suitable for a wide variety of applications where precise control and accurate measurements of resistive elements are needed.
