| description | The utility model discloses an infrared ray electric interruptor controlling magnetic force balancing system which is composed of a lever, a permanent magnetic steel, a coil, an infrared ray electric interruptor and an electronic circuit. When the external force acts on the stressing end of the lever, the lever offsets the equilibrium position to make the shading sheet on the resistance arm of the lever enter the infrared ray electric interruptor. The optical control circuit controls the switch circuit to automatically adjust the output voltage of the voltage regulating circuit. When the coil voltage is definite, the external force (moment) and the magnetic field force are balanced. The shading sheet returns to the equilibrium position. The voltage on the resistance which is strung in the coil is detected to find out the corresponding external force. The utility model is suitable for the instrument, the meter, the weighing and the pressure detecting systems. |
