Rotary Potentiometers and Rheostats are devices designed to measure the resistance of electrical circuits. The PDB185-GTR11-504C2 is a common example, widely used in a range of applications. This article explains its application field, and the working principle of the device.

Application Field

The PDB185-GTR11-504C2 is primarily designed for use with low- and mid-frequency circuits, such as those used in industrial and automotive electronics. These types of circuits often require volatile measurement elements, meaning that they can change when the surrounding environment alters. This is where the PDB185-GTR11-504C2 shines, as it offers reliable and precise measurement values in spite of interference from external challenges. By properly calibrating the device, engineers can get the most out of their measurements.

Some of the most common applications of the PDB185-GTR11-504C2 include motor controls, power supplies, and transducers. This device is also one of the most popular choices in various industrial applications, thanks to its robustly constructed metal housing. It\'s also worth mentioning that the PDB185-GTR11-504C2 was designed in such a way that it can fit into any normal size installation space.

Working Principle

At its core, the PDB185-GTR11-504C2 is a three-pin rotary potentiometer. It has a single resistance element that is connected between three pins; one output pin, one input pin, and a middle adjustment pin. The resistance element itself is made of carbon that has been resistively impregnated with plastic or other insulating material.

When an external voltage is applied to the input pin, a variable transference of resistance occurs between the input and output pins, depending on the rotary movement of the adjustment pin. As the variable resistance changes, the voltage at the output pin also changes accordingly. The degree of resistance establishes the direct relationship between the output voltage and the input voltage.

The potentiometer is designed so that it can be adjusted either digitally or manually. This feature makes it ideal for those applications where varying levels of resistance are needed. By adjusting the potentiometer, the user can adjust the current to maintain a desired level of resistance.

In summary, the PDB185-GTR11-504C2 is a practical and reliable rotary potentiometer and rheostat. It is commonly used in industrial and automotive applications for obtaining precise measurements in spite of environment influences. This device is straightforward to operate, and offers excellent value for money.
