Part of a smart ecosystem

Our interrogators act as the go-between for sensors that detect changing physical conditions and control systems/monitoring platforms.

 

They are interoperable with all types of fiber optic sensors and have an open architecture for easy integration with your control systems, monitoring platforms or cloud storage systems.

 

Want our interrogators to work for you?

Our engineers can provide a custom-made solution.
