Probe penginderaan suhu serat optik fluoresen memiliki banyak keunggulan yang tidak dapat dibandingkan dengan probe penginderaan suhu lainnya, seperti isolasi listrik yang baik, ketahanan terhadap interferensi elektromagnetik, korosi kimia, dan tidak ada polusi. Hal ini membuat probe penginderaan fluoresen tidak hanya digunakan di banyak bidang seperti biologi dan kedokteran, but also have broad application prospects in the power industry. They are mainly used for temperature measurement of high-voltage instruments in electrical equipment, temperature measurement between generator diagnostic systems and transformer windings, temperature measurement of high-voltage circuit breaker contacts, and temperature measurement of high-voltage cable joints.

Introduction to Fluorescent Fiber Optic Sensing Probes
Probe serat optik terdiri dari tiga bagian: konektor ST, kabel serat optik, dan ujung penginderaan suhu akhir. The ST connector is the connection part with the photoelectric module; Fiber optic cable is the transmission part, with quartz fiber inside. The quartz fiber has a coating and cladding on the outside, and a Teflon protective sleeve on the outermost part; The end temperature sensing end contains temperature sensing rare earth materials, which are used to generate optical signals containing temperature information; The optical fiber is resistant to high temperatures of 200 ℃ and has an outer diameter of 3mm. Long term bending radius of 13.2cm. Short term bending radius of 4.4cm. When the distance between the fiber optic lead and the ground is 0.4m, it can withstand a power frequency voltage of 100KV for a duration of 5 menit.

The Temperature Measurement Principle of Fluorescent Sensor Suhu Serat Optik

A sensor suhu serat optik neon is composed of a multimode fiber optic and a fluorescent object (membrane) installed at its top. Zat fluoresen memancarkan energi fluoresensi ketika distimulasi oleh cahaya dengan panjang gelombang tertentu (spektrum terstimulasi). After the incentive is revoked, persistensi pijaran fluoresensi bergantung pada faktor-faktor seperti karakteristik zat fluoresen dan suhu lingkungan. Fluoresensi tereksitasi ini biasanya meluruh secara eksponensial, and the decay time constant is called fluorescence lifetime or fluorescence afterglow time. The attenuation of fluorescence afterglow varies at different ambient temperatures. Karena itu, by measuring the lifespan of fluorescence afterglow, the ambient temperature at that time can be determined.
