PTL30-19O1-103B2 application field and working principle

Slide Potentiometers, such as PTL30-19O1-103B2, are widely used in electronic applications to measure analog signals. They are usually found in household electronics such as ovens and TV remotes, as well as in industrial apparatus, including pumps and air conditioners. The main use for the PTL30-19O1-103B2 is to measure the strength of a signal, for example a voltage, current or frequency. The device functions by providing a path for a variable resistance between two points, and when a signal passes through this resistive path, the output voltage is a direct result of the resistance value.

The working principle of the PTL30-19O1-103B2 is quite simple. The device comprises of a slider which is connected to a circular resistive track via a movable contact. As the slider is moved along the track, the resistance of the track between the two contacts varies, changing the resistance of the path between the contacts from a minimum to a maximum value. The output voltage of the device is then directly related to the barrier potential difference between its two contacts.

To measure an analog signal, the PTL30-19O1-103B2 is connected to a source of electrical power, and the input to be measured is connected to the two contacts of the device. As the input signal is applied, the slider of the PTL30-19O1-103B2 will move along the resistance track, adjusting the resistance of the track between the two contacts. This change of resistance causes a variation in the output voltage of the device, which is directly related to the input signal strength.
