Current temperature sensor manufacturer information recommendation

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 ℃.

how selection - — Current temperature sensor

A, choose current temperature sensors need to pay attention to the hole size can ensure wire can be through the temperature sensor;

B, choose current temperature sensor when the need to pay attention to the application environment for high temperature, low temperature, high humidity, earthquake and other special environment;

C, choice when need to pay attention to the space structure whether meet the current temperature sensor.

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 current temperature sensor and temperature sensor with different characteristics?

temperature sensor is able to be measured by rules and convert the available output signal according to certain rules to the sum of the device or devices, he is made up of two parts, namely, respectively is sensitive components and conversion components. The sensitive element refers to the temperature sensor can feel directly or part of the response is measured; Conversion element refers to the temperature sensor will be sensitive element in feeling or response is measured into electrical signal part of the suitable for transfer or measurement.

when the temperature sensor output is the standards prescribed by the signal, is known as temperature sensor.

temperature sensors is to convert the target signal to standard electrical instrument or equipment, the temperature sensor is a physical signal into electrical signal devices, physical signals used to speak, now there are other signal.

in general current temperature sensor output signal is consistent with the measured signal waveform, is proportional to the relationship. The current temperature sensor is on the basis of the current temperature sensor through adjustment of the circuit will originally followed signal transformation became with the original edge current proportional relationship to the size of the dc signal being measured ( Voltage or current signal) Such as, DC 4 - 20mA, DC 0- 5 v直流0 - 10 v signal, etc. The signal can be standard industrial control products such as PLC, RTU, DAS card, AD collection module acquisition received directly, so normally the auxiliary power supply current temperature sensor is also commonly used DC24V dc power to industrial market.

USES current temperature sensor module note

current temperature sensor will direct current voltage power frequency signals, such as isolation into a 4 - 20mA/0- 10 v, etc all kinds of standard signal on both ends of the semiconductor chip to control the current I, and applying magnetic induction intensity in the vertical direction of the wafer for B and strong magnetic field, is in the direction perpendicular to the current and magnetic field, will produce the electric potential difference as UH voltage.

when measuring current, the use of single wire temperature sensor module aperture, in order to get a better dynamic performance and sensitivity.

the better accuracy of the temperature sensor module was measured under rating, when measured value is lower than the rating, the original with many winding coils, the total ampere turn close to the rating, in order to gain a better measurement accuracy.

when use current temperature sensor module, vice side should be connected to the power supply, then turn on the primary side current or voltage. Current bus temperature shall not exceed 100 degrees.

when choosing temperature sensor module, according to the measuring range, accuracy, reaction time and the parameters such as connection mode, choose different models of temperature sensor.
