Rotary Potentiometers and Rheostats are electromechanical instruments commonly used in electrical engineering. The 81A1D-B28-A10 is a specific type of these commonly used instruments, and its application field and working principle are outlined below.

Application Fields

The 81A1D-B28-A10 is a rotary potentiometer or a rheostat that is typically used in measuring voltage. It can also be used as an adjustable voltage divider for measuring current. The instrument is very useful in applications where an adjustment needs to be made to the current or voltage of a system. It can also be used as a simple way to set an adjustable voltage for various projects.

In addition, rotary potentiometers and rheostats are also used in signal conditioning to modify signals before they enter the analog-to-digital converter. They are often used to set the desired threshold voltage and the gain of the signal. The 81A1D-B28-A10 is a specific type of rotary potentiometer and rheostat that has more accuracy and stability.

Working Principle

Rotary potentiometers and rheostats are both essentially a device that provides resistance in a circuit. When the resistance in the circuit changes, the voltage or current of the circuit is adjusted accordingly. The 81A1D-B28-A10 has a mechanical system of three contact points on a single rotation shaft that is used to adjust the resistance. The shaft is connected to a track that is etched into a ceramic substrate. This allows the resistance to be adjusted with precision.

The 81A1D-B28-A10 also has a construction that helps to ensure stability and accuracy. The three contact points are spring loaded, ensuring that there is no dead zone when rotating the shaft. It also has a high resistance capability, which allows a higher control range for voltage and current. The instrument is also designed to be low noise and low temperature drift, thus making it a reliable and accurate solution.

Conclusion

The 81A1D-B28-A10 is a rotary potentiometer or rheostat that is useful in various applications. It is commonly used to measure voltage or current, as well as for signal conditioning. It has a construction that ensures stability and accuracy, and a high resistance capability. It is a reliable and accurate solution that can provide an adjustable voltage or current for various projects.
