The HTS-1000 sensor enables fiber optic temperature measurements up to 1000 °C. In addition to the traditional benefits of fiber optic sensors, including immunity to electromagnetic interference, better environmental stability and enhanced remote sensing as compared to traditional electronic sensors, the HTS-1000 extends these benefits to ultra-high temperature applications, ranging from turbine engine test and development to refinery process monitoring and control. Microwave environments can be accommodated with an all-glass sensor housing.
The HTS-1000 is based on Chiral Photonics’ chiral diffraction grating, fabricated by twisting a fiber as it is passed through a miniature heat zone to produce a distinct dip in the transmission spectrum. The spectral position of the dip in this chiral fiber changes with temperature allowing it to be used as a temperature sensor.
