The characteristics of the current temperature sensor

both open loop and closed loop hole temperature sensor principle, basic performance difference is not big, basic advantage: fast response time, low temperature drift, high precision, small volume, wide frequency band, strong anti-jamming capability, overload ability.

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.

the development of the current temperature sensor advantage

and the trend of the development of current temperature sensor has the following features:

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, 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.

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.

current temperature sensor is introduced

current temperature sensor mainly through measurement on the current path resistance pressure drop to monitor current circuit ( Although there are other techniques, such as magnetic technology, but the discussion here is limited to parallel resistance current measurements) 。

a and by measuring the current temperature sensor output current is proportional to the voltage or current of the path. Thanks to it's widely used to measure current. Traditionally, the current sensor is mainly used for circuit protection and reports, but with the development of technology, current of induction as a means of monitoring performance and become increasingly important, and the purpose of monitoring performance is improved.
