Roctest FOT-F & FOT-N Temperature Sensors
FOT-F and FOT-N temperature transducers combine all the desired characteristics expected from an ideal sensor. Their compact size, immunity to EMI/RFI/Lightning, resistance to corrosive environments, high accuracy and reliability make them the best choice for temperature measurements in harsh environments. Fiber-optic temperature gauges are based on the thermal expansion of highly stable glass allowing for precise, stable, and repeatable measurements.
The protection tube of the FOT-N is smaller in size than the FOT-F which comes equipped with an NPT stainless steel fitting. The FOT-F can be installed on vacuum and high pressure environments or high voltage applications whereas the FOT-N is mainly used for the embedment in concrete or in open air. Both models are fitted with the extrinsic Fabry-Perot fiber-optic transducers enclosed inside a protective stainless steel tube.
Readout units and data loggers are designed for civil engineering, R&D, industrial applications. Then have a built-in data logging capability for up to 50 000 measuring points. The fiber-optic lead cable can be up to several kilometers long.
