Tips: Application of Hall current sensor in retrofit distribution system
Open-loop Hall effect current sensor is mainly used in factory transformation of DC distribution system, such as power plant DC power system transformation, substation DC system transformation, communication room transformation, railway locomotive transformation and other projects. It can transform the system original coil DC Current signal into a standard DC ±5V or 4-20mA output signal. It plays the role of monitoring and electrical isolation and can be used in conjunction with multi channels monitoring instruments or other electrical measuring instruments. DC system transformation without power outage, engineering transformation is very difficult. Using traditional closed core hall current sensor or shunt cannot be resolved, and so the split-core open-loop Hall current sensor could be used to solve the DC current metering problem, to ensure that it is not power outage and safe in the engineering transformation process.
Hall effect AC current sensors have non-invasive structure, with 1.0%FS accuracy, 1ms fast response time, 0-400A ~ 0-20000A measuring range, 4-20mA output signal, 12V/24V power supply, excellent linearity and strong anti-interference capacity. Open loop AC current sensors can be connected to AD, DSP and PLC directly. AC current sensors are now widely used for high current measurement of control systems.
