Cores and Shields
Enhancing and Protecting Current Sensors
Two of the most important components of a current sensor are the core and shield used to concentrate magnetic flux and protect the sensor from external magnetic fields. CTS provides both in various sizes and materials along with add-on features to make installation easy.
Current Sensor Components
When developing a current sensor, it is important to consider the choice of components that will work within the sensor. Dimensions, laminations, shapes, and materials can make or break the strength of the sensor when it comes to the design.
Cores
The core, also known as the concentrator, is a crucial component of a current sensor that channels the magnetic flux generated by the electric current. At the center of the core is an air gap, where a sensor—typically a Hall sensor—is positioned to detect the magnetic field precisely.
LU-Shield
The LU-Shield is a soft ferromagnetic shield that protects against external magnetic fields and features superior material characteristics such as high linearity and very low hysteresis. This design uses iron lamination to support harsher environments and making this particular shield more suitable for high-speed applications.
U-Shield
The U-Shield is a soft ferromagnetic shield that protects against external magnetic fields and featurs superior material characteristics such as high linearity and very low hysteresis. The shield is designed for planar current sensing in combination with a Hall sensor, AMR sensor, and a busbar conductor.
