The classification of the current temperature sensor

current temperature sensor on the basis of measuring principle is different, the main can be divided into: the shunt, electromagnetic current transformer, electronic current transformer, etc.

including hall current temperature sensor, Luo Kefu electronic current transformer, current temperature sensor and is dedicated to frequency conversion power measurement AnyWay frequency conversion power temperature sensor ( Can be used for the voltage, current and power measurement) And so on.

current temperature sensor is also called magnetic temperature sensors, can be in household appliances, smart grid, electric vehicles, wind power, etc. , are used in our life a lot of magnetic temperature sensors, such as computer hard drives, compass, household appliances and so on.

the application of the current temperature sensor

with the continuous development of modern industrial technology, the current widely used in the field of industrial control, industrial control of electric current detection precision and response speed of the demand is higher, at the same time hope completely isolated and tested object implementation, current temperature sensor has solved these problems well. Current temperature sensor for its excellent performance and ingenious structure, has become the field of industrial control current isolation measurement solutions, and is widely used in the drive, and high frequency inverter, motor winding current measurement, etc.

when using the current temperature sensor needs to pay attention to?

in most cases, the current temperature sensor has a strong ability to resist the external magnetic field interference, general module 5 - in the distance 10 cm between a two times the magnetic field generated by the current Ip of current interference can be ignored, but when have stronger magnetic field interference, to take appropriate measures to deal with.

usually methods are: (1) adjust the direction of the module, the external magnetic field of the influence of the small module; (2) on the module with cover a magnetic field the metal shield resistance; Choose a with hall element in two or three hall element module; (4) measuring accuracy is under the rating, when the measured current is far lower than the rating for accuracy, the original edge can use number of turns, namely: IpNp = rated ampere turn. In addition, the original edge feeder temperature should not exceed 80 ℃.
