Opsens Solutions’ fabrication processes ensure an exact definition of the gauge factor, making OSP-A sensor the most accurate fiber-optic strain gauge sensor in the industry.
Combined with Opsens’ WLPI signal conditioner technology (Patent #7,259,862) and the inherent advantages of fiber optics, the OSP-A delivers unprecedented repeatability and reliability in the most adverse conditions such as high levels of electromagnetic fields as well as high voltage and rapid temperature cycling conditions.
The OSP-A uses two optical fibers that are precisely aligned inside a microcapillary tube to form an optical Fabry-Pérot interferometer. This makes the OSP-A strain gauge completely immune to any electromagnetic interference.
It is completely insensitive to transverse strains and temperatures and its micro-miniature size makes the OSP-A fiber optic sensor ideal for space-constrained applications such as intelligent load-sensing bolts and studs. Careful choice of materials for the sensor, fiber coating and cable buffering permit a high temperature operating range from -40 °C to +250 °C.
This miniature and robust fiber optic strain gauge sensor, available in different cables and sheath options, may be customized to customer specific requirements or for OEM-type applications.
