摘要： A sensor device includes a tubular body having a first end and a second end opposite the first end, a pressure plug on the first end of the tubular body, and a sensor tip on the second end of the tubular body, wherein the sensor tip comprises an open end opposite the tubular body and an optical tip removably positioned through the open end and held in place by a removable cap. The optical tip includes an optical rod and a rod holder. The sensor device further includes an optical fiber extending from the pressure plug, through the tubular body, and into the sensor tip where the optical fiber is optically coupled to the optical rod. The pressure plug may include a slack cavity where the optical fiber is in slack under neutral temperature and pressure conditions to withstand expansion of the sensor device under high temperature or pressure conditions.
