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.

what is the difference between current temperature sensor and current transformer?

ac/dc current temperature sensor can detect and measure communication communication, measuring dc dc, need an external power source.

only measuring AC current transformer, the output signal of AC 5 a or AC1A, don't need the power converter.

common current transformer can only measure the alternating current, if the open circuit can produce high voltage, ac current transformer breakdown line insulation, serious when produce blow electrical personnel security, so, when using secondary side cannot open circuit, short break secondary side must meet.

the current temperature sensor anti-interference

electromagnetic field

closed loop hall effect current temperature sensor, the use of the original edge the electromagnetic principle of wire. Thus the following factors directly affect the temperature sensor is affected by external electromagnetic interference.

( 1) Temperature sensor near the external current size and current frequency change;

( 2) Outer conductor and the distance of the temperature sensor, the external shape, location, and the temperature sensor of the wire inside hall of electrode position;

( 3) Installation temperature sensor used by material with and without magnetic;

( 4) Temperature sensor is used by the current block;

in order to minimize the interference of external electromagnetic field, according to the installation guide to install the temperature sensor.

current temperature sensor - — Electromagnetic compatibility

electromagnetic compatibility EMC, ( 电- - - - - - 磁兼容性) Is the study of electrical and electronic equipment that can perform their respective functions in common electromagnetic environment state of coexistence, the requirements of the various devices in the same electromagnetic environment can work normally and noninterference, achieve 'compatibility' state a discipline. The deterioration of space electromagnetic environment is more and more easy to make electronic components caused by incompatible between false action in the system, so the electrical and electronic equipment electromagnetic compatibility testing is very necessary. Due to the urgent needs of the actual production, scientific research and marketing, has passed the electromagnetic compatibility test a consensus has emerged among current and voltage of temperature sensor, and has become a compulsory standards.
