Core Technologies & How They Work This Fibre Optic Sensor, functioning as an Amplifier Switch, operates by utilising light to detect changes in its environment. Instead of electrical signals, it transmits light through a fibre cable. The sensor then interprets variations in this light, such as intensity or wavelength, to trigger an output. This particular model, the E3X-NA11, and the E3X-NA41, can provide either an NPN or PNP output, indicating its versatility for different control systems. Its operating voltage range is 10-30V DC, making it suitable for a variety of industrial applications. Fiber Bragg Grating (FBG) Fiber Bragg Grating (FBG) is a common method for fibre optic sensing, particularly for temperature and strain. An FBG is a periodic change in the refractive index within the core of an optical fibre, which reflects a specific wavelength of light while transmitting others. When the fibre is subjected to changes in temperature or strain, the grating period alters, causing a shift in the reflected wavelength. This shift is then measured to determine the environmental change. While this Fibre Optic Sensor is an Amplifier Switch, the underlying principles of how fibre optic temperature sensors work often involve such grating technologies. Fluorescence (Phosphor Decay) Fluorescence, specifically phosphor decay, is another method employed in some fibre optic sensors, often for temperature measurement. This technique involves a sensor tip coated with a fluorescent material. When excited by a light source, this material emits light. The decay time of this emitted light is temperature-dependent. By measuring how quickly the fluorescence fades, the sensor can accurately determine the temperature. This is one way how fibre optic temperature sensors work, offering robust performance in challenging electromagnetic environments. Distributed Temperature Sensing (DTS) Distributed Temperature Sensing (DTS) systems use the entire length of a fibre optic cable as a sensor. They work by sending a laser pulse down the fibre and analysing the backscattered light. Specifically, changes in the Raman scattering spectrum are correlated with temperature variations along the fibre. This allows for continuous temperature profiling over long distances. While this product is an Amplifier Switch, understanding how fibre optic sensors work, especially for temperature, often involves principles like DTS for comprehensive monitoring. GaAs (Gallium Arsenide) Bandgap Gallium Arsenide (GaAs) bandgap technology is utilised in some fibre optic temperature sensors. The fundamental principle is that the bandgap energy of GaAs is temperature-dependent. A sensor using this technology incorporates a small GaAs crystal at the fibre tip. When light is transmitted through the fibre to the crystal, the absorption spectrum of the GaAs shifts with temperature. By measuring this shift, the sensor can precisely determine the temperature. This is another example of how a fibre optic temperature sensor works, providing accurate readings in various conditions.
