FS62RSS应变传感器

FS62RSS – 坚固型应变传感器

混凝土浇筑前嵌入到结构中,适合监控工程应用

测量范围 ±2500µm/m

兼容常规混凝土结构

对于温度补偿,请考虑使用 FS63RTS 温度传感器

Description

The Rugged Strain Sensor is a Fiber Bragg Grating (FBG) based sensor designed to be to be embedded inside concrete material. Engineered as a roboust solution with outdoor cable rated for embedding in concrete.

The FS62RSS is based on the newLight® technology developed by HBM FiberSensing to combine particular advantages of the FBG overcoming technical compromises that existed so far. newLight® sensors employ high strength fiber coatings and different FBG fabrication techniques to ensure increased strain measurement ranges, enhanced fatigue resistance and higher measurement accuracy. The low bend loss, telecom compatible fiber opens the possibilities for innovative sensor designs as well as the straightforward usage of multiplexed sensors on the same fiber even if kilometers apart. The technology is completely passive, self-referenced and compatible with most interrogators.

Combine this with other strain and temperature sensors from HBM FiberSensing with armor cables by using the configurator K-FS76ARM.

Benefits and applications
