Current temperature sensor description

small fusion power equipment has been more and more new technology. For example, switching power supply, hard switching, soft switch, voltage regulator, linear feedback regulator, magnetic amplifier technology, numerical control, PWM, SPWM voltage regulator, electromagnetic compatibility and so on. Actual demand directly boost power technology development and progress continuously, in order to automatically detect and display current, and the over-current, over-voltage and other dangerous happens with automatic protection function and higher level of intelligent control, with sensing monitoring, sampling, sensing protection of power technology is a trend, the temperature of the test current or voltage sensor arises at the historic moment and gets gradually the favour of the general power supply designers in our country.

the definition of the current temperature sensor

current temperature sensor, is a kind of detection device, can feel the information of the measured current, and can detect feel the information, will change according to certain rule as meets the needs of a certain standard electrical signal output, or other form of information needed to satisfy the information transmission, processing, storage, display, record and control requirements. 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 use of the superiority

the disadvantages of using shunt is not electrical isolation, and insertion loss, the electric current, the greater the loss, the greater the volume is, the greater the shunt can still be found in testing high frequency current with inevitable inductive, not real measured current waveform, more can't real transfer non sine wave. Current temperature sensor completely eliminates the shunt the above shortcomings, and accuracy and can output voltage and shunt, such as precision of 0. 5, 1. Output voltage level 0, 50, 75 mv and 100 mv.

current temperature sensor model selection

1. Is a clear need to detect is ac or dc current, what is the scope to measure current, due to the actual electricity load current range is larger, so the current temperature sensor can be classified according to the size of the current, low current sensor and temperature sensor with large current.

2. What is the output, current or voltage, such as the output voltage is 4 v.

3. The specifications of the auxiliary power - - - Alternating current temperature sensor in order to accurately detect the change of the input current, also in order to be output to the input current into dc signal of linear change, usually need a auxiliary power supply more current temperature sensor work power, such as power supply voltage of power supply voltage, + 15 v.

4. Current temperature sensor input overload capacity.

5. Determine the ambient temperature.

6 the precision of the temperature sensor, determine some of the needs of high precision, so emphasize accuracy when the choice, choose high precision current temperature sensor.

7 the appearance of the temperature sensor is very important, such as guide rail is installed, circuit board installation, aperture is round or square, the choice is all of these need to be considered.
