Optical sensing points
Compact passive sensing points positioned close to the physics that matter inside the asset.

Inside the asset.
CEKO Sensors delivers optical MEMS sensing systems for critical parameters inside transformers and other demanding high-voltage equipment. The measurement point is placed where the relevant physical behaviour occurs — inside the asset, not merely on the outside of the tank.
The essential difference
Conventional transformer monitoring often relies on measurements taken outside the active part. CEKO places the sensing point inside — closer to the physical conditions that define asset behaviour and health.
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.

SDAS Insight
Field-ready interrogation, control and data handling in one unit outside the high-voltage zone.

Usable data
Measurements are turned into live dashboards, trends and condition information for operators and partners.
Continuous · remote · decision-readyTransformer monitoring
Measurements from inside the transformer.
The defining difference is where the sensing happens: inside the transformer and other demanding high-voltage equipment, while interrogation and data handling remain accessible outside.

MEMS technology
From wafer-level structures to field data.
The CEKO platform combines microfabricated optical sensing structures, fiber-based signal transmission and scalable system integration.
- Wafer-level MEMS platform developed for optical sensing.
- Signal transmission by fiber, with the readout kept outside the asset.
- A scalable sensing architecture rather than a one-off point solution.
Evidence
Built across the full chain.
CEKO develops the complete measurement chain, spanning wafer-level structures, laboratory validation, field deployment and operational data presentation.
Fabrication & lab work
Development spans MEMS work, packaging and validation in controlled environments.
Measured performance
Representative measured performance from the optical MEMS platform.
System architecture
Multiplexed optical sensing brings several sensing points into one coherent readout architecture.
Applications
One platform. Multiple demanding environments.
Transformers and related high-voltage assets are the primary focus. The same optical MEMS platform can also support other demanding environments where remote, passive sensing creates value.
Transformers & HV equipment
CEKO focuses on sensing critical parameters from inside transformers and other high-voltage assets — not just from the outside of the tank.
