Rogowski coils (see Sidebar and References 1 and 2 at end) perform passive current measurement and are used in test and measurement devices and power-monitoring activities. Calibration is required to ...

Relays and solenoids are available with many different voltage ratings. Most factory- and process-automation equipment operates from 24-V supplies. However, customers may have control signals for a ...

Numerous test-and-measurement applications require a high-frequency magnetic field. Oftentimes, high field strength is needed. Examples of such applications include bio-medicine research on the effect ...

Work coils, also referred to as the inductor, are a part in an induction heating system. Their purpose is to indicate whether a work piece has been heated effectively and efficiently. There are ...

High frequency Helmholtz coils are often used to generate uniform but time varying high frequency magnetic fields for a number of applications such as magnetic field susceptibility, calibration, and ...
