Fiber Optic Temperature Sensors

OpSens’ optic temperature sensors are perfectly tailored for devices and therapies using energy extremes, high or low. They can also survive radiated environments and are immune to microwave energy. These sensors are designed to be used in broad range of environments, from cryogenic to high temperatures, up to 350 degrees Celsius.

OpSens’ fiber optic temperature sensor is designed to provide accurate real-time temperature monitoring during MR, RF ablation, hyperthermia therapy and electro-surgical procedures. This compact tip sensing temperature transducer is available as skin surface, core, nasal, and oesophageal probes.
