The characteristics of the current temperature sensor

1, the high sensitivity. Detected signal strength is more and more weak, this will require a magnetic temperature sensor sensitivity are improved greatly. Applications include Angle of the current temperature sensors, temperature sensors, gear temperature measurement sensor, the space environment.

2, temperature stability. More applications require temperature sensor working environment more and more severe, which requires the magnetic temperature sensor must have good temperature stability, industry applications include automotive electronics industry.

3, anti-interference. A lot of field temperature sensor using the environment without any comparison, requires a temperature sensor itself has a good anti-jamming. Including automotive electronics, water meter and so on.

1, miniaturization, integration, intelligence. If you want to do the above requirements, which requires the integration of the chip level and module level integration, product integration.

2, the high frequency characteristics. As the application in the field of promotion for the work frequency of the temperature sensor is higher and higher, application areas include water meter, auto electronics industry, information industry.

3, low power consumption. Many areas for low power consumption of the temperature sensor itself, to extend the service life of the temperature sensor. Used in the implanted in the body of magnetic biological chip, compass and so on.

the use of the current temperature sensor information

wiring in A, when the exposed conductive part of terminals, as far as possible to prevent ESD, needs A professional construction experience of the engineers to to the terminal operation. Power supply, input and output of each connecting wire must be properly connected, dislocation or reverse connect, otherwise may cause damage of product.

B, use the product installation environment should be no conductive dust and corrosive

C, violent vibration or high temperature may also lead to product damage, must pay attention to use the occasion.

current temperature sensor main characteristic parameters of the

1, the standard rating ISN IPN and rated output current.

IPN refers to the current temperature sensor can test the standard rating, expressed in RMS ( 武器) Product model, the size of IPN and the temperature sensor, ISN refers to the current temperature sensor rated output current, generally is 10 ~ 400 ma, of course, according to certain models may be different.

2, the offset current ISO.

offset current is also called the residual current and residual current, it is mainly by the components or electronic operational amplifier working state of the temperature sensor circuit of current instability, caused by the current temperature sensor in the production, at 25 ℃, IP = 0, the offset current is modulated to smaller, but the temperature sensor production line when you leave, will produce certain size of the offset current.

3, linearity.

linearity determines the temperature sensor output signal, Vice side current IS) With the input signal, Primary side current IP) Within the measuring range is proportional to the degree.

4, temperature drift.

offset current ISO is calculated in 25 ℃, when electrode surrounding environment temperature change, ISO can produce change, therefore, consider the large variation of the offset current ISO is very important, among them, the IOT is refers to the temperature drift in the current temperature sensor performance table values.
