Alternating current temperature sensor manufacturers welcome the calls

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.

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 ℃.

current temperature sensor - — Technology introduction

current temperature sensor using technology is important, because different temperature sensor may have different characteristics in various applications. Most of the temperature sensor can work, because the current-carrying wire creates a magnetic field. When directly measure the current in the circuit, will use the current sense resistor.

induction - Induction temperature sensor using a coil, the current-carrying conductor through the coil. This leads to the power flowing in the coil, is proportional to the current. This is due to the flow of electric current of magnetic fields. Induction temperature sensor is used for alternating current. The temperature sensor has a line around the core and signal conditioner. When the current through the conductor core conductor magnetic field will enlarge it. Due to alternating current constant electric potential from negative to positive, Usually for 50 to 60 Hz) Expand and contract, so will produce magnetic field, so the current is induced in the winding. Voltage and secondary current is converted to be adjusted for the output process. 4 - signal, for example 20 ma or contact closure.

magnetic resistance - Magnetic resistance effect is some material to change its resistance value as a function of the applied in its magnetic field characteristics. If it is not applied to magnetic flux, the current will directly through the plate. If the imposed magnetic flux and magnetic flux density is proportional to the lorentz force will make current path deflection. As the current path deflection, current flows through the plate distance is longer, resulting in increased resistance.
