USES and features of current temperature sensor manufacturer 'photos'

An overview of the current temperature sensor

( 1) Output end concentrated by large electrolytic and noise reduction

( 2) 1 n4004 capacitance uF, diode.

（ 3) Transformer according to the power consumption of the temperature sensor.

（ 4) The temperature sensor's working current. Direct detection ( No amplification) Power: big to 5 ma; Straight test amplified power consumption: big to + 20 ma; Magnetic compensating power consumption: 20 output current; Consumption of working current 20 2 times the output current. According to the working current consumption power consumption can be calculated.

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.

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.

current temperature sensor in the control and protection of the door into the system, the application of

the door into the system must provide security and protection for the users. Imagine a garage door locked people or cars in consequence. Current measurements can provide this kind of protection function.

electronic systems control garage doors, shutter and awning is gradually into People's Daily lives, and the protection performance is the most important function of must be taken into account when designing these systems. Current measurements can provide this kind of protection function.

used in garage doors, doors, shutters and awning on dc brush motor, at every time of normal opening and closing to produce its own repeatability of current distribution. The current waveform can be stored in the microcontroller. Current temperature sensor can provide dc brush motor current feedback at work, the door into the system manufacturer defined tolerance range, to that of the current waveform is stored in the microcontroller in the comparison. If the values do not match, the security problems. Micro controller will be alert and closed system or reverse rotation motor, to close the door again. The obstacles, person, or other object provides protection, at the same time protect the motor from damage caused by high current.
