Opsens Solutions’ OTP-A fiber optic temperature sensor offers the highest performances in the industry. The OTP-A sensor (Patent #7.259.862) uses the temperature-dependent birefringence of specially selected crystal as the temperature transduction mechanism. Because of the pure monocrystalline material used, the OTP-A does not shows thermal creeping or aging as with other fiber optic sensors based on the thermal dilatation of glass optical fibers.
Combined with Opsens Solutions’ WLPI signal conditioning technology (Patent #7.259.862) and with the inherent advantages of fiber optics, the OTP-A delivers unprecedented repeatability and reliability in the most adverse conditions such as high level of EM, RF, MR and microwave fields environments as well as with high voltage and rapid temperature cycling conditions.
The standard operating range of the OTP-A is from -40 °C to +250 °C. Higher temperature ranges up to 350 °C are available upon request. A high resolution and accuracy version is also available (see OTP-M model).
The OTP-A is compatible with all Opsens Solutions’ WLPI signal conditioners. This compact and robust fiber optic temperature sensor, available in different cables and sheath options, is customizable according to customer specific applications or for OEM-type applications.
