Hall effect current sensors/DC current sensors: As mentioned above, these sensors use the Hall effect to measure AC and DC currents.The coil is a flexible current transformer that provides a series of benefits for practical use. Firstly, they are easier to install than traditional current transformers. Thin coils can be easily wound around conductors and quickly closed. This makes them very suitable for use in situations where installation may be tricky, and you are using live wires，Splitting core current sensors can open and capture surrounding conductors, making them easier to install in pre-existing configurations. Although they are considered less accurate than solid core current sensors, their precision is sufficient for almost all practical applications.

Solid core: Solid core current transformers are complete loops that cannot be opened, so when installing cables, the cables must be disconnected and placed through the current transformer. This makes them most suitable for new installations. They provide high precision,Open loop: Hall effect sensors can be in an open or closed loop. Open loop sensors provide low insertion loss, fast response time, compact size, accurate, and low-cost sensing.

Closed loop: Closed loop sensors provide fast response, high linearity, and low temperature drift. The current output of closed-loop sensors has relative immunity to electrical noise. Closed loop sensors are sometimes referred to as "zero flux" sensors because their Hall effect sensors feed back opposite currents to the secondary coil, winding around the magnetic core to counteract the magnetic flux generated by the primary current in the core.
