Intelligent module series products are our latest new generation of electrical measurement series products, using a new intelligent product design, abandoning the analog circuit design concept of traditional analog sensors, adopting digital and modular design schemes, and changing the traditional analog wiring design method with intelligent digital bus design. The intelligent module and sensor detection system make the configuration equipment assembly process more concise, the equipment digitalization and automation degree higher, and the equipment debugging more convenient.Digital Hall current sensor is a new type of digital current detection sensor, which can replace the current mainstream conventional Hall current sensor in the market. The digital Hall current sensor adopts a new intelligent bus design method. The output of a single digital Hall current sensor It is connected in parallel to the digital communication bus through physical connection, and is connected to the upper computer through the digital communication bus interface, and all sampling data are transmitted to the upper computer in the way of bus addressing. The thus formed current detection system has the advantages of simple process, low production cost and high degree of automation.
