Optical Strain Gauge OL-LT: Fiber Bragg Grating (FBG) based Sensor with Extended Temperature Range

The Optical Strain Gauge OL-LT is designed to be glued to straight or curved surfaces to measure both positive and negative strains in structures and materials.

Featuring a wide temperature measurement operation range, the OL-LT measures high strains over a high number of cycles and is able to operate under extreme climate conditions, such as the ones found in Aerospace applications.

Temperature Resistant

  • Operation under wide temperature range (-40°C to +100°C)

Suitable for all climate conditions whether extreme heat or freezing cold


  • Inherent immunity to all electromagnetic effects (EMI, RFI, sparks, etc)
  • Electrical isolation

Accurate results in adverse conditions (e.g. potentially explosive environments, high voltage areas and intense electromagnetic fields)


  • Patented sensor design  with outstanding bending capability (6 micron core fiber)

  • Plastic packaging

High quality measurements during 24/7 operation even on curved surfaces


  • Easy handling and simple installation of multiple sensors in a single optical fiber

Benefiting from both optical sensor technology and a wide range of accessories for electrical strain gauges
