FOT Embeddable Temperature Sensor
COMPACT SIZE
GOOD REPEATABILITY
IDEAL FOR HARSH ENVIRONMENTS
The compact size, immunity to EMI/RFI/Lightning, resistance to corrosive environments, makes the FOT-N the best choice for temperature measurements in harsh environments.
FOT-N temperature transducer combines all the desired characteristics expected from the ideal sensor. Its compact size, immunity to EMI/RFI/lightning, resistance to corrosive environments, high accuracy and reliability makes it the best choice for temperature measurements in harsh environments. Our fiber optic temperature gauges are based on the thermal expansion of highly stable glass, allowing precise, stable, and repeatable measurements.
FOT-N is mainly used for embedment in concrete or in open air. It is fitted with the extrinsic Fabry-Perot fiber optic transducers enclosed inside a protective PVC or stainless steel tube.
Our readout units and dataloggers are designed for civil engineering, R&D, industrial applications and have a built-in datalogging capability for up to 50 000 measuring points.
