Product Description
Analog MeterFeaturesEs
This series of products has two types: electromagnetic type and magnetoelectric type, which are suitable for control systems or power distribution systems, and display corresponding electrical parameters, such as AC and DC current, AC and DC voltage, power factor, frequency, etc.
Structural features of pointer instruments
Magnetoelectric type: the basic operating mechanism is an internal magnetic structure. The AC current/voltmeter is made by adding a thyristor rectifier circuit to the DC pointer of the internal magnetic structure. Since the rectification circuit is separated from the measuring mechanism, it is easy to maintain.
Electromagnetic type: composed of watch case, dial, coil, bracket, fixed iron core parts, moving iron, pointer, hairspring, good overload capacity and low cost.
The cover and body are made of crystal synthetic glass and black plastic respectively.
Pointer instrument standards and certificates:
Production standard: GB/T7676-1998
Safety performance specification: GB4793
Dial design specification: German standard DIN43790
Dial pointer design specification: German standard DIN43790
Instrument appearance production standard: GB/T1242
Instrument opening size production standard: IEC61554
International safety certification: CE
