1. Що є Флуоресцентні волоконно-оптичні датчики температури?

Fluorescent fiber optic temperature sensor probes utilize rare earth crystal fluorescence lifetime-temperature correlation for precision measurement. Ці оптичні датчики температури operate entirely on optical principles, with probe bodies constructed from optical materials and ceramic or stainless steel enclosures, containing no metallic conductive components.

Core Operating Mechanism

Rare earth fluorescent material at the probe tip emits fluorescence when illuminated by excitation light. The fluorescence decay time changes with temperature variations. The передавач температури precisely measures this decay time to calculate accurate temperature values. This process requires no electrical signals, providing inherent interference immunity.

Basic System Architecture

Повний флуоресцентна волоконно-оптична система моніторингу температури comprises three main components: the optical temperature transmitter (signal acquisition and processing), quartz fiber optic transmission cable (optical signal pathway), and fluorescent sensing probe (temperature-sensitive element). This modular design allows flexible configuration based on site conditions.

Contact Temperature Measurement Advantages

Unlike non-contact methods such as infrared thermal imaging, флуоресцентні зонди make direct contact with measured object surfaces, obtaining actual temperatures rather than surface radiation temperatures.
