Tip Configurations
Conax Buffalo Technologies’ Fiber Optic temperaturemeasurement system provides extremely accurate and
reliable measurement in high temperature applications.In
this system,an emissive material at the probe tip is inserted
into the process or flow path.As the process or flow stream
heats the probe tip,the emissive material generates thermal
radiation in both the visible and non-visible spectrum.This
energy is transmitted along a sapphire light guide within the
probe housing and then through a rugged yet flexible fiberoptic cable to the Electro Optic Unit (EOU).The ruggedconstruction of this cable allows it to survive the harsh
environmental conditions often found in applications rangingfrom aircraft engines to steel mills.The Electro Optic Unit receives the broadband opticalradiation from the probe,analyzes it over two wavelengths,and converts it into a digital signal that is transmitted to the
Digital Signal Processor (INDUSTRIAL DSP).The Digital Signal Processorthen computes the correct temperature and generates thespecified output type.This system offers the following advantages over traditionalthermocouple measurement systems:
OSP1Open emissive sapphire sensor for static environmentOSP2Protected emissive sapphire sensor for high velocity environmentOSP3Protected emissive sapphire fiber sensor for high velocity environment
Stability & Repeatability - The fiber optic system is notsubject to the base metal contamination and resultant signal
degeneration found with traditional thermocouples usingprecious metals and refractory metals.The signal isconsistently stable with superior repeatability.
