With sensitivity of 0.01-nm/°C (nominal), a fiber optic temperature sensor from Chiral Photonics covers a temperature range up to 1,000°C. The sensor was designed for applications ranging from weld monitoring and control, to turbine engine service and design. The sensing element is a monolithic glass fiber. It is not reliant on any moving parts or coatings and the sensor packaging can be tailored to suit the application needs The probe (metal sheathing) has a length of 300-mm standard (other lengths available upon request), and sensor/grating length of 15-mm. Sensor placement is 25-mm from probe tip, and the connector type is FC/APC.
