Differenzwiderstände

Differenzwiderstände, also known as differential resistors, are electronic components used to measure the difference in voltage between two points in a circuit. They are commonly employed in instrumentation and control systems to provide accurate and reliable measurements. Differenzwiderstände are typically made from materials with high resistance and low temperature coefficient, such as metal film or carbon film, to ensure stability and precision.

The basic principle behind Differenzwiderstände is that they are connected in a bridge circuit, where the voltage difference across the resistor is proportional to the current flowing through it. This allows for the measurement of small voltage differences with high accuracy. Differenzwiderstände are often used in applications where high precision is required, such as in medical equipment, industrial automation, and scientific research.

One of the key advantages of Differenzwiderstände is their ability to reject common-mode signals, which are signals that are present at both inputs of the measurement circuit. This makes them ideal for use in noisy environments, where other types of resistors may be susceptible to interference. Additionally, Differenzwiderstände are typically designed to have a low temperature coefficient, which means that their resistance value remains stable over a wide range of temperatures.

In summary, Differenzwiderstände are specialized resistors used for precise voltage measurement in instrumentation and control systems. Their ability to reject common-mode signals and maintain stability over a wide range of temperatures makes them a valuable component in many applications.
