Manufacturer of high frequency alternating current temperature sensor manufacturers recommend 'information effectively for a long time'

Current temperature sensor in the use of the superiority

( 1) Non-contact detection. In imported equipment to transform, and the technical reformation of old equipment, shows the advantages of non-contact measurement; The electrical wiring of original equipment without the slightest change can be measured, the value of electric current.

（ 2) Is very easy to use in a LT100 - C current temperature sensor, in series with the M side and power zero a 100 ma analog meter or digital multimeter, working power supply is connected, will be set back to the way the wire, temperature sensor can accurately show the main circuit of 0 ~ 100 a current value.

the current temperature sensor installation direction applied to wind power

current temperature sensor in each current temperature sensor has an arrow on the casing of the direction of the arrow represents the flow of current to be measured, at the edge of the temperature sensor of the original access current to be measured, to ensure that the measured current and direction of flow and temperature sensors on the direction of arrow shown, otherwise it will lead to reverse the temperature sensor output signal.

voltage temperature sensors in each temperature sensor shell will have on the edge of the positive and negative voltage, respectively used to access the voltage signal is being measured, the anode, some temperature sensors with grounding will output 'E', the terminal connected to the shield, usually to be connected to the protected area, to play a role shielding and anti-interference, it is important to remind that although the temperature sensor can be ac/dc general, but the direction of the original edge access will also bring vice side of the output change, the former vice edge waveform will appear reverse current temperature sensor.

to measure the current of electrical current, the larger the original edge is commonly punch structure, according to the shape of the perforation, size to choose the appropriate cable or copper platoon, ensure that the original conductor can smoothly through the perforation, don't damage due to excessive conductor cross section temperature sensor perforation, wear heart conductor should be full of perforation, as far as possible to ensure the accuracy of measurement, cables and copper platoon through the temperature sensor, both sides have the fixed support, in the middle as far as possible, avoid copper platoon or cable askew, lest affect the measurement result, need to pay attention to the temperature of the conductor in the actual operation, better not more than nominal allowed temperature, in order to avoid overheating affect the normal work of the temperature sensor, temperature sensor or damaged.

general temperature sensor of the specifications of the book will have the wiring diagram, express the serial number of corresponding output point, generally includes the positive Vc + power supply, power supply cathode current temperature sensor Vc - M, and the output signal end, as well as the OV, must according to the definition of the serial number to wiring, not wrong, fumble, otherwise it will damage the 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, etc. , based on current temperature sensor measuring principle, main can be divided into: the shunt, electromagnetic current transformer, electronic current transformer, etc.

compared with electromagnetic current sensing current temperature sensors, electronic current transformer is no ferromagnetic saturation, transmission band width, the secondary load capacity is small, small size, light weight, is the development direction of current temperature sensor.

the future development of current temperature sensor wiring way,

1, temperature stability, nowadays many use the local environment temperature temperature sensor is bad, it's a challenge on the stability of the temperature of the temperature sensor, temperature stability better products will be popular.

2, high sensitivity, some application fields are detection of weak signal, which requires the sensitivity of the current temperature sensor need to be greatly enhanced.

3, anti-interference, now there are many interference sources in our life, which requires the current temperature sensor has good anti-interference.

the main characteristic parameters of current temperature sensor

1, linear,

linear determines the current temperature sensor output signal, Secondary current IS) And the input signal, The primary current IP) Is proportional to the measurement range.

2, temperature drift

offset current ISO at 25 ° C is calculated. When hall electrode surrounding environment temperature changes, the ISO will change. Therefore, it is very important to consider the large variation of the offset current ISO, including IOT refers to the current temperature drift of temperature sensor performance table as well.
