Fiber Optic
Temperature Sensors

Opsens fiber optic temperature sensors provide second to none performance to various industries. Offered in two different temperature sensing technologies.

The WLPI (White light interferometry) technology optical temperature sensor is highly robust, offers a resolution of 0.05°C the highest in the industry and an excellent accuracy of ± 0.15°C. Using the monocrystaline birefringence crystal as temperature transduction, The OTP series does not show thermal creeping or aging.

The Gallium Arsenide − GaAs (SCBG) technology OTG series optical sensor is available in diverse packaging. It is the smallest optical sensor in the industry with a dimensionof 0.170mm OD offering a fast response time of less than 10ms. With an accuracy of ± 0.3°C and resolution of 0.05°C, it is designed to meet the requirements for the life sciences and medical industry. The OTG sensors is available as surface sensing probe offering superior surface temperature measurement and most robust packaging for oil filled transformer winding temperature monitoring.
