INDUCTIVE SENSING ARRANGEMENT

INDUCTIVE SENSING ARRANGEMENT

An inductive sensing arrangement (20) includes a loop antenna (26) and a signal generator (24) for driving the antenna, these forming a resonator circuit (22). The resonator circuit is drivable in a drive state in which the antenna is driven at resonance to thereby generate electromagnetic signals....

Zusammenfassung:An inductive sensing arrangement (20) includes a loop antenna (26) and a signal generator (24) for driving the antenna, these forming a resonator circuit (22). The resonator circuit is drivable in a drive state in which the antenna is driven at resonance to thereby generate electromagnetic signals. The arrangement further includes a switching means (28) for switchably inhibiting the drive state of the antenna. This allows in use controllable switching of the antenna in and out of the drive state to thereby control switching signal generation on and off.
