Title:
トランスデューサ装置
Document Type and Number:
Japanese Patent JP4562228
Kind Code:
B2
Abstract:
The control circuit 12 generates an alternating voltage Ve through a flip-flop 13, preferably with inverter switches laid out in H form, in order to excite the oscillating circuit 11. The voltage Ve is made synchronous with the current i that passes through the transducer by means of a phasing device 14 that comprises 2 transistors T1, T2 coupled through their basis to an output 13b from the flip-flop and through their emitters to a terminal of the oscillating circuit. The link of the transducer with its control circuit is made using two wires only.
