The OpECS (Optical Electric Current Sensor) is a groundbreaking sensor system that leverages the Faraday effect to detect magnetic fields produced by electric current — translating them into measurable electrical signals with exceptional accuracy and safety.
Instead of relying on a current shunt, transformer, or hall effect sensor, OpECS utilizes polarized light modulation. When a current flows through a conductor, the magnetic field around it alters the polarization of the light at the sensor tip. This light is sent to a control unit, where it is converted back into an electrical signal and output via BNC for waveform monitoring.
Its tiny optical probe can be placed near or against the wire being measured. The closer it is to the wire's center, the higher the sensitivity. This makes it possible to measure currents beyond the rated ±140 A by varying the probe distance — making it scalable for both small-signal and high-current applications.
The OpECS is especially effective in applications where:
-
Isolation is mandatory
-
Contactless probing is needed
-
Space is severely limited
-
High-speed transient current detection is critical
