The problem of stability of optical fiber strain gauge sensing element under simultaneous variations of deformation and temperature is considered. Fiber Bragg gratings is used as one of the most promising sensor elements of fiber-optic gauges. A sensing element based on two Bragg gratings with different specially selected coatings is developed. It is shown that the structure of the developed sensing element allows for separation of the influence of strain from temperature effects.
