CNC Electric According to the principle of division

1. Meter and electronic sensors into two categories:

Principle of induction meter uses electromagnetic induction to the voltage, current, phase change magnetic moment, pushing aluminum disc rotation axis of the disc (worm) current transformer‍ drive gear drive counters and the drum rotates, the rotation of the process that is the amount of time cumulative process. Therefore, the benefits of induction meter is intuitive, dynamic continuous power does not lose data.

Induction meter high requirements on the process, involving a wide range of material, metal, plastics, precious stones, glass, rare earth and so on, to which the relevant material standard products and requirements are clearly defined, with cheap inferior materials instead of the standard specifications of materials is one of the main problems that affect product quality meter, so like most commodities, low commodity prices will not have a good quality assurance.

Complex production process induction meter, but already mature and stable, but also comprehensive support tooling equipment. Production requirements temperature, humidity and air purification degrees higher.

Electronic energy meter using analog or digital circuits to get the product of voltage and current vector, and then implement the energy measurement functions with analog or lectri calmete‍ digital circuits. Since the application of digital technology, sharing billing meter, prepaid energy meter, multi-user power meter, multifunction power meter have appeared, and further meet the science of electricity and reasonable demand for electricity.

Currently Overall, induction meter, compared with the electronic energy meter, induction meter quantity produced as much. But production of electronic power meters have a clear upward trend.

2. Press the accuracy of measuring the power of classification, there is a general and two tables: one represents meter error does not exceed ± 1%; 2 represents meter error does not exceed ± 2%

3. Press the additional function division, multiple rate meter, prepaid energy meter, energy meter multi-user, multi-function meter, power meter and other carriers. Multi-rate meter or meter, said sharing, multi-rate table, commonly known as peak table, is a measurement instruments in recent years to meet the needs of TOU tariff provided. It can be pre-peak, valley, usually divided into segments, each metering peak, trough, flat section of electricity, and thus different time with different electricity tariffs, tariff regulation play, encourage electricity customers adjust electricity load, peak load shifting, rational use of power resources to fully tap, supply, potential electrical equipment, is an electronic or electromechanical meter; commonly known as prepayment meter card table, with IC card pre-order power, the IC card is inserted in the table can be controlled by the cost of electricity to prevent electricity arrears, is electronic or electromechanical meter; power transformers‍ multi-user meter a watch for multiple users, independent accounting of each user, so you can reach the purpose of saving resources and easy to manage, but also conducive to the centralized remote automatic meter reading, is the electronic energy meter; multifunction meter set a number of functions in one, is the electronic energy meter; carrier Meter use power line carrier technology for centralized remote automatic meter reading, is the electronic energy meter.
