Abstract
PURPOSE: To maintain initial condidtions always near constant as far as supply voltage does not fluctuate by providing a plurality of resistors having iso or hetero characteristics in proximity on the same substrate thereby constituting the strain gauge.
CONSTITUTION: Resistors 22 printed on a substrate 21 consist of two portions of different sections, provided with three lead wires 25 thru 27. The strain gauge 9 constituted in this way is mounted to the bottom 5 of a washing tank 1 and the lead wires 25, 27 are connected to a power source 16. Water pupply to the washing tank 1 is automatically controlled by the water supply solenoid valve 11 which is opened and closed by a solenoid 12. Namely, the gate 14 of a thyristor 13 is controlled by the voltage V between the lead wires 25, 26 when the tank bottom 5 makes elastic deformation and the water supply solenoid valve 11 is controlled by the solenoid 12. Thereby, the water level of the washing tank 1 is always kept at a normal level Ho.
