Distributed Temperature Sensing (DTS) system is ideal for detecting fire and monitoring temperature profiles over long-distances. Our fiber optic sensor temperature measurement solutions provide enhanced visibility into your process, allowing you to detect problems before. Fiber optic temperature sensors are immune to the many environmental effects that compromise other measurement technologies, can be embedded and installed in locations traditional temperature sensors cannot and deliver an unprecedented level of spatial detail and data without sacrificing precision. Distributed Temperature Sensing (DTS) systems provide temperature information for accurate thermal monitoring, fire detection, and condition assessment by utilizing standard fiber optic cables. By using the Raman Scattering principle, the temperature distribution along the entire length of an optical fiber cable and the location of temperature anomalies can be determined.

The paper describes a technique to determine the refractive index of liquids using reflective type fiber optic displacement sensor. The sensor consists of two multimode step index fibers and a mirror. This review is focused on microstructured optical fiber sensors developed in recent years for liquid RI sensing. The output light intensity from the receiving fiber is measured as a function of displacement of. In this present work we report fabrication of fiber optic liquid refractive index (RI) measurement sensor based on Michelson Interferometer method. This sensor was assembled by using graded index multimode (MM) fiber with core diameter 50 µm and the cladding of fiber was removed by simple chemical.
