Optical MEMS sensing for high-voltage equipment

Optical sensing.
Closer to the physics.

CEKO Sensors develops optical MEMS technology and monitoring systems for demanding industrial applications. Passive optical sensing points can be integrated closer to the relevant physical behaviour, while interrogation and system electronics remain externally accessible.

The essential difference

Conventional monitoring often relies on measurements taken at an accessible distance from the process of interest. CEKO enables passive optical sensing closer to the relevant physical conditions, while keeping interrogation and conventional electronics in an accessible location.

Platform

Sensor. Fiber. Insight.

The system is built as a complete measurement chain: a passive sensing point, optical transmission, and a field-ready readout unit.
