What is the Maximum Operating Temperature of a DTG® Sensor?


The maximum operating temperature for an ORMOCER®-coated DTG® is about 200°C.  During high temperature exposure, the reflectivity of the DTG® will be slightly reduced but also stabilized.  Depending on the type of measurement, FBGS recommends a pre-annealing process to increase the stability of the grating wavelength.  For applications at >200°C, please contact us at info@fbgs.com for more information.
