Both FOT-L temperature sensors feature complete immunity to EMI and RFI,
miniature size, built-in safety for hazardous environments, extreme temperature
resistance, high precision, and resistance to corrosive environments.
Fiber optic technology provides intrinsic immunity to EMI and RFI. Fiber optic
sensors are not electronically active and do not emit nor are they affected by any
type of EM radiation, whether it is microwave, RF, or NMR.
Another important advantage of optical bers is the capability it provides to
produce miniature components without compromising the physical characteristics
of the bulk material. Optical ber is optimized in size to provide the smallest
possible light path. Thanks to this advantage, ber optic sensors may feature tip
diameters as small as 0.8 mm.
FISO’s ber optic temperature sensors provide accurate, stable, and repeatable
measurements. These measurements are based on variations of the reected
light — when compared to the emitted light — due to thermal expansion of the
highly stable glass used within the sensor.
The FOT-L-SD is sheathed with PTFE and has a temperature range from as low as
−40°C up to 300°C (−40°F to 572°F).
The FOT-L-BA is designed with a much smaller diameter to provide an even faster
response time, while withstand temperatures of up to 250°C.
All our temperature sensors are designed to work with FISO’s line of signal conditioners.
The ber optic lead cable can be up to several meters long without affecting the
quality or the accuracy of the results.

The FOT-L-SD and FOT-L-BA are ber 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.
