Inductive Systems

Different from Radio-systems, in Inductive systems the range is not maximized but limited to a clearly defined area by the size and shape of the magnetic antenna.

Representative applications are RFID (RF-Identification) and EAS- (Electronic Anti Shoplifting) systems and metal-detectors.

Precise remote measurement of distance, position or movements of tags or metal objects, is an other application with RF magnetic fields.
For a medical research project, a system for remote monitoring of movements inside organs has been constructed.

A special inductive sensor is our Distant Temperature Sensor where with an isolated tag with LC-circuit, temperature (or other parameters) can be monitored.
Measurement of temperature is possible in separate places outside the range of optical IR-sensors, and with temperatures out of range for active semiconductor sensors or active data loggers.

Wireless Energy Transfer which the intention of replacing the waste-full batteries in many semi-portable devices is another specialism with RF magnetic fields.
