OpSens’ OTP-M is designed to perform in high field MR environments by offering the highest temperature accuracy and resolution in the industry.
The OTP-M sensor uses the temperature-dependent birefringence of a crystal specially selected for life science applications as the temperature transduction mechanism. Because of the pure monocrystalline material used, the OTP-M 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’ WLPI signal conditioning technology (patent #7.259.862) and with the inherent advantages of fiber optics, the OTP-M is able to address the medical industry’s requirements for long term accuracy, repeatability, low drift and high resolution in rapid thermal cycling conditions under the presence of strong EM, RF, MR and microwave fields.
The OTP-M is compatible with the WLPI AccuSens and AccuSens-OEM signal conditioners. This compact and precise fiber optic temperature sensor, available in different cables and sheath options, is customizable according to client specific or OEM applications.
Compatibility : Use with any of OpSens’ AccuSens signal conditioner
