Fiber optic temperature sensors are advanced IoT devices that utilize optical fibers, which are thin strands of glass or plastic. They transmit light and detect even the most minor temperature changes. With the fundamental properties of light, such as intensity, polarization, and wavelength, these fiber optic temperature sensors measure external faults with high sensitivity and accuracy.
A key characteristic of fiber optic sensors is their immunity to electromagnetic interference (EMI). This ensures durability and reliability even in extreme conditions.
Fiber optic sensors also offer robust build, intrinsic safety, and capability for distributed sensing over long distances. Thus, making them highly suitable for applications across industries, including utilities, renewable energy, data centers, and EV charging stations.
The working principle of fiber optic temperature sensors is based on the modulation of light properties as it travels through or reflects from an optic fiber. These modulations are correlated with the fluctuations in temperature of the monitored asset.
Rugged Monitoring’s fiber optic sensors are based on the key mechanisms of GaAs-Based Temperature Sensing. Our temperature sensors are designed with Gallium Arsenide (GaAs) crystals as their fiber tip. They measure temperature fluctuations through shifts in their absorption spectrum. As the temperature increases, the transmission properties of GaAs adjust. This ensures highly accurate (+/-0.2 °C) and real-time temperature readings (response time of 0.2s).
Rugged Monitoring’s GaAs fiber optic sensors are easy to install and are based on proven zero-drift GaAs technology. They are designed to surpass transformer lifespan. This makes them highly suitable for utilities, OEMs, and high-voltage environments.
Compared to traditional temperature sensors, Rugged Monitoring’s fiber optic temperature sensors provide resistance to harsh environmental conditions (with PTFE coating). This includes corrosion, radiation, and high temperatures, ensuring asset safety even in high-voltage and extreme environments. Our advanced solutions also enable continuous temperature sensing without signal degradation over long distances and narrow spaces. This is due to their small form factor (1-1.5mm).
Our fiber optic sensors also offers heavy-duty protection, outstanding repeatability, and plug-and-play operations. Thus, meeting a wide range of industry requirements and dynamic working conditions.
