The advantages of current sensors in terms of performance and functionality

Firstly, the current sensor adopts the principle of isolated measurement. For example, the most common electromagnetic sensor does not need to be directly connected to the current during measurement, but measures through electromagnetic induction, which can achieve ideal measurement accuracy. Moreover, since the sensor is isolated from the circuit, there is no need to worry about sensor damage due to strong current. At the same time, this principle also brings convenience to installation. Most products only need to pass the cable through the sensor to be used directly. In addition, it has also greatly improved in measurement accuracy. Even in very precise instruments, it can output accurate data in real time, making it convenient to measure current and effectively ensuring the safety of users.

Another significant advantage of current sensors is that they have a wide frequency band, which means they can measure changes in current at different frequencies. Nowadays, many devices require the use of high-frequency signals. For example, when driving a motor, modulated AC power is used to operate the rotor, and the frequency needs to be adjusted according to the situation. By using sensors, frequency changes can be measured at any time, ensuring accuracy whether operating at very low frequencies or reaching very high frequencies. At the same time, high frequency bandwidth also brings more convenience to circuit design, as there is no need to choose sensor models based on the characteristics of current frequency. The same sensor can use circuits with different frequency characteristics.

Finally, it is worth mentioning the stability of the current sensor, which can operate normally in various complex and harsh environments. For example, in many industrial environments, temperature can undergo drastic changes, but sensors can ensure normal operation at both high and low temperatures, and their accuracy will not be significantly affected. Even in the presence of electromagnetic interference, accurate data can still be output without serious errors caused by electromagnetic environment issues.

Our high-precision current sensor products have a range from 1mA to 25kA and are constantly expanding in models. The accuracy can be provided in multiple series, with a range of 1 ‰~1ppm. The voltage sensor range is from 100V~2kV, with an accuracy of 1 ‰~0.5 ‰. The working temperature range can reach -40~+85 ℃, and the measurement accuracy is world leading.
