OTG-R Fiber Optic Temperature Sensors

Convenient for bridge wire assembly and temperature monitoring for HERO/RADHAZ applications

About the OTG-R Fiber Optic Temperature Sensors

Fiber optic temperature sensor for Hero/Radhaz applications.

The OTG-R fiber optic temperature sensor offers the highest performances in the industry. The probe is perfectly tailored for reliable measurement of Electromagnetic Environmental Effects on Electrically Initiated Devices (EID's). 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 of the optical fiber makes it convenient for bridge wire assembly and temperature monitoring for HERO/RADHAZ applications.

The sensor is immune to mechanical vibration and accepts extension cables without any signal degradation. With a high response time of < 275 ms for MK1 and high resolution of < 35 dB below NFT, the OTG_R delivers unprecedented repeatability and reliability in the most adverse conditions such as high level of EM, RF, MR, and microwave field environments.

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