South African fluorescent fiber optic temperature sensor

Fluorescent fiber optic temperature sensors in South Africa offer high-accuracy, EMI-immune, and reliable temperature monitoring for industrial and research applications.

Overview and Working Principle

Fluorescent fiber optic temperature sensors operate based on fluorescence. A fluorescent material (fluorophore or phosphor) is excited by a light source, such as an LED or laser, and emits light at a longer wavelength. Temperature is determined by either: Intensity-based sensing: Measures changes in fluorescence intensity with temperature, though it can be influenced by external factors.

Lifetime-based sensing: Measures the decay time of fluorescence after excitation, providing high accuracy and stability, largely independent of light source fluctuations or optical path losses. These sensors are particularly suitable for harsh environments, offering immunity to electromagnetic interference, intrinsic safety, fast response, and long lifespan.
