The characteristics of Hall sensor current: The isolation end refers to the active measurement end of the sensor being electrically isolated. High voltage current sensors are designed for high-voltage applications. The definition of intrinsic safety equipment is "equipment and circuits that, under normal or abnormal conditions, cannot release sufficient electrical or thermal energy to ignite a specific hazardous atmospheric mixture at the most easily ignited concentration. This is achieved by limiting electrical equipment in hazardous areas to levels below which gases can ignite. When using such products, it is important to pay attention to the installation environment and avoid placing the signal end too close to the tested end to prevent electrical faults.

Hall sensor current has various applications. For example, some devices are used for energy metering, control system diagnosis, current supply measurement, and control of complex loads on electric motors. Others are used for charging integration and monitoring the status of rechargeable batteries. Specialized current sensors, such as those used in commercial appliances, typically come with safety cutoff and surge tripping functions. High voltage current sensors can also be provided. The current sensor installed on the printed circuit board combines the advantages of small footprint with the advantages of signal processing, which can be achieved by using existing microprocessors.
