万彩网100线路 Hall effect current sensors can be used to monitor DC or AC currents. This series of products includes adjustable linear, zero balance, digital, and linear current sensors. So how to choose a Hall current sensor? Let Weikewei introduce it to you below.

万彩网100线路The CSN series magnetoresistance current sensor uses ASIC (Application Specific Integrated Circuit) and Honeywell magnetoresistance (MR) sensors, with extremely low temperature drift, resulting in stable measurement results, good repeatability, and high accuracy. This is because the ASIC used fully utilizes the unique characteristics of the magneto resistive sensor. It is designed based on Honeywell's patented technology and can provide excellent sensor performance and extremely high accuracy in current measurement applications.

万彩网100线路Before making a choice, it is necessary to conduct research on all aspects related to the operation of Hall current sensors. To understand the characteristics of the measured object, such as its state, properties, measurement range, amplitude, and frequency band, measurement speed, time, accuracy requirements, overload amplitude, and frequency of occurrence.

1. Wide measurement range: It can measure current and voltage of any waveform, such as DC, AC, pulse, triangular waveform, etc., and even faithfully reflect transient peak current and voltage signals;

2. Fast response time: The fastest response time is only 1us.

3. High measurement accuracy: Its measurement accuracy is better than 1%, which is suitable for measuring any waveform. Ordinary transformers are inductive components that affect the waveform of the measured signal when connected. Their general accuracy is 3% to 5%, and they are only suitable for 50Hz sine waveforms.

万彩网100线路4. Good linearity: better than 0.2%

万彩网100线路5. Good dynamic performance: fast response time, can be less than 1us; The response time of ordinary transformers is 10-20ms.

6. Wide working frequency band: signals within the frequency range of 0~100KHz can be measured.

7. High reliability and long mean time between failures: Mean time between failures>; 510 hours

万彩网100线路8. Strong overload capacity and large measurement range: 0- tens of amperes to tens of thousands of amperes

万彩网100线路9. Small size, light weight, and easy installation.

万彩网100线路Due to the advantages of Hall current and voltage sensors, they can be widely used in frequency conversion speed control devices, inverter devices, UPS power supplies, inverter welding machines, electrolytic plating, CNC machine tools, microcomputer monitoring systems, power grid monitoring systems, and various fields that require isolation and detection of current and voltage.

ChooseHall Current Sensor 万彩网100线路There are many aspects and matters that need to be considered, and it is impossible and unnecessary to meet all requirements in practice. Designers should start from the overall purpose and requirements of using Hall current sensors in the system, comprehensively analyze the main and secondary aspects, weigh the pros and cons, grasp the important aspects, highlight important issues and give priority consideration. On this basis, the specific issues for selecting the type of Hall current sensor can be clarified: the size of the range and the overload amount; Requirements for the weight and volume of Hall current sensors for the tested object or location; The measurement method is contact.
