This sensor uses a capillary tube as the packaging carrier, is internally equipped with a quartz or sapphire FBG element, and uses stainless steel or a high-temperature alloy as the substrate. The quartz FBG version is suitable for -40～1000℃, and the sapphire FBG version is suitable for -40～1500℃, with a temperature sensitivity of approximately 10 pm/℃, a temperature drift of ±1.0℃, and a center wavelength within the range of 1510～1590 nm. The standard size is φ1 mm×1 m, and other lengths are supported for customization. The overall structure is compact and can be fixed to high-temperature components by welding or bonding, making it suitable for industrial sites that require long-term monitoring or multiple measurements. If you are evaluating whether it is suitable for your equipment or project, you are welcome to contact us and provide the temperature measurement range, installation method, and required length, and we will assist in confirming the configuration.
