Electric Meter Model Demo Physical Electrical Circuit Experiment Equipment for Education Science Experiment Tools

Structure and Working Principle: The internal magnetic structure of high-quality magnetic steel makes the magnetic stability of the meter, high sensitivity, light weight and easy to carry. It is an intuitive teaching aid for studying the structure of the magnetoelectricity meter in the teaching. The meter has good intuitiveness, high visibility, convenient operation and reasonable structure. Specification: Product Name: Demo Electric Meter Length: 27cm/10.6inch Width: 21cm/8.2inch Quantity: 1 Pcs Use for:,school,,gift Package Includes: 1 x Demo Electric Meter Note: Please allow little color difference due to different display or light environment. Because it is a manual measurement, the product size has a small range error of 0.5-1cm, please refer to the actual product, please understand.

• It can be used to measure DC current, DC voltage, and can also be used as a galvanometer.
• The instrument is a magneto-electric sy structure, which is mainly composed of a meter head and a measuring circuit.
• The meter head is composed of a high-quality magnetic steel inner magnetic bracket, a yoke ring, a moving ring, a hairspring, a shaft tip seat and a bearing.
• When the current passes through the moving coil, a magnetic field is generated to interact with the magnetic field generated by the inner magnetic support and the yoke to generate a rotating torque and deflect the moving coil.
• When the rotating torque is balanced with the reaction torque produced by the hairspring, the pointer is in the balance position, indicating the measured value, and a mechanical zero adjustment knob is installed at the back of the meter.
