Current temperature sensor manufacturers supply good price 'the long-term effective information'

What is the difference between current temperature sensor and current transformer?

ac/dc current temperature sensor can detect and measure communication communication, measuring dc dc, need an external power source.

only measuring AC current transformer, the output signal of AC 5 a or AC1A, don't need the power converter.

common current transformer can only measure the alternating current, if the open circuit can produce high voltage, ac current transformer breakdown line insulation, serious when produce blow electrical personnel security, so, when using secondary side cannot open circuit, short break secondary side must meet.

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.

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.
