OTG-A Fiber Optic Temperature Sensors

Small sensing GaAs crystal located at the tip of the optical fiber makes it convenient for tip measurement applications


About the OTG-A Fiber Optic Temperature Sensors

GaAs-based fiber optic temperature sensor for R&D and industrial applications.

The OTG-A fiber optic temperature sensor offers the highest performances in the industry. The sensor uses the well proven technique based on the temperature-dependent bandgap of GaAs crystal as the temperature transduction mechanism. Its small sensing GaAs crystal located at the tip of the optical fiber makes it convenient for tip measurement applications.

It delivers unprecedented repeatability and reliability in the most adverse conditions such as high level of EM, RF, MR and microwave field environments.

This precise and robust sensor is available with different optical cables lengths. Fully customizable according to your specific application.
