This standard specifies the terminology, characteristic performance parameters and related test methods of fibre optic temperature sensors based on one of the most sensitive sensor techniques available, fibre Bragg gratings, which can simultaneously measure temperature and strain. Fiber-optic high-temperature sensors are gradually replacing traditional electronic sensors due to their small size, resistance to electromagnetic interference, remote detection, multiplexing, and distributed measurement advantages. 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. Stability and repeatability under thermal cycling are hallmarks of a reliable and useful thermometer. Each ch nel on a device is calibrated toST-bushing on each side and require no maintenanc side and - 40 require °C to 120 no °C.
