Principio della misurazione della temperatura della fibra fluorescente
Photoluminescence
The phenomenon of photoluminescence is the mechanism of fluorescence fiber temperature measurement technology. Photoluminescence refers to the phenomenon in which certain specific fluorescent materials are stimulated to emit light beyond thermal radiation. According to Planck’s law, when a substance is excited by some form of energy, it will produce a transition process of electrons between energy levels E1 and E2 (E1<E2), and emit light waves with a wavelength of λ.
After being irradiated by excitation light, fluorescent materials will produce fluorescence when the excitation light is removed. The fluorescence intensity generated gradually decreases, and the time required to decay to 1/e of the maximum fluorescence intensity at excitation is called fluorescence lifetime.
There is a monotonic relationship between fluorescence lifetime and temperature, and temperature measurement is achieved by measuring fluorescence lifetime.

3、Tempsens Instrument Pvt. Ltd.
FluoroSenz Fiber Optic Temperature Monitoring System conducts real time monitoring to accurately measure point temperatures of hotspots including Transformers, Switchgears, Generators. It is specially designed for harsh environment where High Electric and Magnetic fields are present. The system is based on Calibration free Fluorescence Time Decay Technology, which ensures no recalibration is required over the lifespan of the sensor. The size of Optical Fiber Sensor is very small and it can be easily installed on the measuring point with high measurement accuracy and fast response frequency. Supporting up to 16 Sensors, the temperature of each can be read on the local 7-Segment Display or remotely monitored on PC through various communication provided. The system is supplied with a User Friendly Software which shows real-time data readings along with graphical representation.
4、OSENSA’s Optical Fluorescent Sensor Technology
OSENSA’s temperature sensing technology is also unique in that it can be both contact and non-contact. After applying a specially prepared formulation of sensitive material to an object of interest, its temperature can be read. This is a particularly valuable feature for characterizing temperatures of critical electronic components and profiling the thermal heat distribution over larger objects. A fiber optic probe can be brought close enough to the sensing material to read its temperature, without causing stem conduction losses from electrical wires, and without the need to strategically place and route thermocouple leads everywhere. The optical temperature reading is more accurate than an Infrared (IR) camera reading, and at a fraction of the cost.
5、SA Instruments, Inc
Fiber optic temperature probes provide an alternative method to thermister temperature probes for measuring temperature. The fiber optic temperature probes use florescence technology to make accurate and reliable temperature measurements. Despite the fact that the probes are small, flexible and made from optical fiber, they are remarkably durable. Fiber Optic Temperature is available as an option for the MR-compatible Model 1025 e 1030 Monitoring & Gating Systems and for the Model 1025L and 1025T systems for use PET, CT, SPECT, Optical and in the laboratory. The fiber optic temperature probes have a tip diameter of 0.040″ OD (1 millimetro) or 0.120″ (3 millimetro). Standard probe lengths are 2’ and 6’. Fiber optic temperature extension cables are also available. Fiber optic temperature probes are MR and CT-compatible.
