Current temperature sensor using the matters needing attention

( 1) The better precision of current voltage temperature sensor is under the condition of the original edge rating, so when the measured current is higher than the current rating of temperature sensor, should choose the corresponding big temperature sensor; When the measured voltage is higher than the voltage rating, temperature sensor should readjust current limiting resistor. When the measured current is lower than the rating of 1/2 below, in order to get a better precision, can use more than the number of circle.

（ 2) Insulation withstand voltage of 3 kv temperature sensor can work for a long time in communication system and 1 1 kv and below. Dc system, 5 kv and below 6 kv temperature sensors can work for a long time in communication system, and 2 kv and below 2. Dc system 5 kv and below, be careful not to use overpressure.

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 in the application of motor

temperature sensors and motors, drives, controller a motion control system or drive system. Current temperature sensor is commonly used in motor drive and control of the temperature sensor, platinum spark plugs, the output signal is used as a function of protection, feedback, no temperature sensor in the motor control, the current temperature sensor is the indispensable element, the current signal is used to calculate the magnetic field physical quantities such as position and flux linkage and torque. In different kinds of motors even the same type but different in the number of motor drive, the location and type of temperature sensor are also different voltage temperature sensor, temperature sensor, the hall current ( voltage sensor) 。

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.
