FOT-L Fiber Optic Temperature Sensors 

The FOT-L-SD and FOT-L-BA are fiber optic temperature sensors perfectly suited for harsh environmental conditions such as in cryogenics, nuclear, microwave, and strong RF applications. The FOT-L temperature sensors combine all the desired characteristics you would expect from the ideal sensor. These temperature sensors offer accuracy and reliability in extreme temperature and hostile environments.
