Guangdong current wireless temperature sensor manufacturer price quotation

Current temperature sensor in the use of the superiority

1. Measuring range: it can measure arbitrary waveform of current and voltage, such as dc, ac, pulse, triangle waveform, even for the transient peak current, voltage signal can faithfully reflect;

2. Fast response: the KuaiZhe response time for 1 us.

3. High precision measurement, the measurement accuracy is better than 1%, the accuracy is suitable for any waveform measurement. Ordinary transformer is sensitive device, access after affect measured signal waveform, the average accuracy is 3% ~ 5%, and only suitable for 50 hz sine waveform.

4. Good linearity: better than 0. 2%

5. Good dynamic performance, fast response time, but less than 1 us. The response time of the ordinary transformer is 10 ~ 20 ms.

6. Working width: in 0 ~ 100 KHZ frequency range of the signal can be measured.

7. High reliability, long average trouble-free working time: the average time without obstacles, '5 10 hours

8. Overload capacity is strong, large measuring range: 0 - - - Dozens of ampere ~ tens of thousands of ampere

9. Small volume, light weight, easy to install.

the connection mode of current temperature sensor

1, a phase type wiring, which is used to measure the phase or three phase ( Through the switch) Electric current.

2, differential connection, usually used in the relay protection circuit, such as lines or transverse differential protection, motor protection and capacitor and it can reflect all kinds of short circuit.

3, star connection, measuring load balanced or unbalanced three-phase power system of three phase current, the connection mode of three phase, two phase short circuit and single-phase grounding short circuit with the same sensitivity, high reliability.

4, incomplete star connection, also calls the v-shaped connection, used to measure the load balanced or unbalanced three-phase three-wire system line current, current temperature sensor is not completely y connection of relay protection circuit, can seal all kinds of alternate with short circuit protection.

select current temperature sensor note

of 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, in general, choose AC220V is more easy to obtain, can also choose to dc power supply, such as: DC24V, etc. , it is important to note that some of the current temperature sensor, that does not need auxiliary power supply, the so-called 'passive' current temperature sensor.

how to choose the current temperature sensor

, a clear need to measure the dc current, pulse current, or ac current.

general test signal is only a single temperature sensor, temperature sensor can only test the dc signal, some can only test the ac signal, and high precision magnetic flux gate current temperature sensor is the ac/dc.

2, to understand the accuracy of the test.

accuracy is one of the important performance index of the current temperature sensor, because of the different industry, the precision of the temperature sensor for current requirements are different, when we choose current temperature sensor, the first thing to know that we need what kind of accuracy, precision 2 PPM / 5 PPM / 10 PPM of current temperature sensor.
