What are the types of fiber optic temperature measurement systems available

1. Fluorescent fiber optic temperature measurement system

Fluorescent powder temperature measurement, fluorescence afterglow temperature measurement, fluorescence lifetime temperature measurement, fluorescence fiber temperature sensor probe is made of rare earth fluorescent substance, which excites fluorescence after being irradiated with fixed wavelength light. After the excitation stops, the relationship between the decay time constant of fluorescence afterglow and temperature is a quasi exponential function. The temperature can be obtained by measuring the time constant of the afterglow. The fluorescence fiber optic system consists of a fluorescence fiber optic sensing probe, an IF-C2B16F20 fiber optic temperature transmitter, an IF-YS10F liquid crystal display instrument (configured according to requirements), a fluorescence fiber optic temperature measurement system background monitoring computer, and a fluorescence fiber optic background monitoring software.
