Title: Fiber optic temperature sensor measurement for geothermal plant

Geothermal power is a significant source of cost effective, reliable, sustainable and environmentally friendly green energy. A 60kW, 1000 m well-depth pilot geothermal power plant was commissioned in Yi-Lan, Taiwan. Continuous and accurate monitoring of down-well temperature profile is critical to peak generator performance and efficiency. The temperature profile must be measured at a depth of 300 m up to 230 C and conventional methods are not suitable The Solution was a fiber optic sensing solution from Micron Optics composed of an sm125 Optical Sensing Interrogator combined with optical fiber Bragg grating (FBG) sensors from 3L Technologies (Taiwan) the system provided was accurate, reliable and robust for continuous down-well temperature measurements to maximize energy production Mircon Optics claims an approximately 50% reduction in capital investment versus competing optical technologies.
