Non-Intrusive Current Sensor

The CTS-CS-CXX magnetic field concentrators are designed for non-intrusive and isolated measurements of electric currents. Thanks to the clamp-on design, the contactless current sensor can be safely installed without the need to interrupt or cut the cable. A full demonstrator assembly is also avaliable with our clamp on solution directly mounted on a PCB fully calibrated (CTS-CS-CAX).

 

Contactless Current Sensor Ideal for High-Accuracy

These contactless current sensors utilize Hall-effect technology for non-intrusive measurement of the magnetic field generated by a conductor, such as a busbar or wire. The clamp-on design allows for safe installation without interrupting or cutting the cable. The field concentrator is split into two pieces that wrap around or 'clamp' onto the conductor. The bottom half can be directly soldered to a PCB using its four through-hole pins, ensuring a secure and robust connection. The sensor is integrated into the full module via the PCB.

We have developed a non-intrusive clamp-on module (CTS-CS-CAX), which integrates a magnetic field concentrator and a Melexis IMC-Hall® current sensor. A streamlined version, featuring only the magnetic field concentrator, is also available (CTS-CS-CXX).

The CTS-CS-CAX module includes a PCB with a Melexis IMC-Hall® planar current sensor, a CTS-CS-CXX clamp-on shield, and all the necessary components for easy installation and operation. Supplied with a DC voltage of 5V, the module provides a linear analog output voltage between 500 mV and 4500 mV as a function of the primary input current. The module offers an excellent linearity error, below 0.5 %FS and the integrated Melexis IMC-Hall® current sensor provides an excellent offset, as low as ±5 mV and sensitivity drift of 1 % over full temperature range.

The CTS-CS-CXX is designed for non-intrusive and isolated measurements of electric currents. The magnetic field concentrator is comprised of a soft ferromagnetic shield featuring superior material characteristics such as high linearity and very low hysteresis.
