TEMPERATURE SENSOR USING AN OPTICAL FIBER

摘要

A temperature sensor that has an elongated sensing element having a length of at least 10 m, measured at a temperature of 20.degree.C. The elongated sensing element includes an elongated jacket and an optical fiber mounted in the jacket and having an EFL of at least 0.35%, wherein the elongated sensing element has an average temperature error of less than 2.degree.C.
