Induction Coil Sensors – a Review
نویسنده
چکیده
The induction coil sensors (called also search coils, pickup coils or magnetic loop sensors) are described. The design methods of air coils and ferromagnetic core coils are compared and summarized. The frequency properties of the coil sensors are analyzed and various methods of output signal processing are presented. Special kinds of induction sensors, as Rogowski coil, gradiometer sensors, vibrating coil sensors, tangential field sensors and needle probes are described. The application of coil sensor as magnetic antenna is presented. Index Terms – coil sensor, magnetic field measurement, search coil, Rogowski coil, vibrating coil, gradiometer, integrator circuit, H-coil sensor, needle probe method.

متن کاملEnergy Scavenging for Wireless Sensor Networks
Conventional condition monitoring of electrical machinery is conducted by measuring signals such as currents and vibrations outside the motor. Wireless sensors now provide a means of accessing and measuring useful signals inside the motor where the phenomena responsible for failure occur. These sensors are capable of not merely sensing, but also processing, storage and eventually communication....
متن کاملWireless Metal Detection and Surface Coverage Sensing for All-Surface Induction Heating
All-surface induction heating systems, typically comprising small-area coils, face a major challenge in detecting the presence of a metallic vessel and identifying its partial surface coverage over the coils to determine which of the coils to power up. The difficulty arises due to the fact that the user can heat vessels made of a wide variety of metals (and their alloys). To address this proble...

متن کاملIntracerebral hemorrhage (ICH) evaluation with a novel magnetic induction sensor: a preliminary study using the Chinese head model.
Biomedical magnetic induction measurement is a promising method for the detection of intracerebral hemorrhage (ICH), especially in China. Aiming at overcoming the problem of low sensitivity, a magnetic induction sensor is chosen to replace the conventional sensors. It uses a two-arm Archimedean spiral coil as the exciter and a circular coil as the receiver. In order to carry out high-fidelity s...
