The device comprises a balance having two magnets attached thereto, a coil combining pick-up and driving functions, two complementary transistors, an RC circuit formed of a speed-up first condenser and a first resistor, a biasing second resistor, a coupling second condenser a third resistor and a third condenser. This device is capable of operating over a wide temperature range, is less influenced by the deviation generally seen in the commercially available transistors, is simplified in construction, is inexpensive to manufacture and is adapted for mass production.
