About This Product
■Measure vibration with high precision
Measuring acceleration is even easier
■Low frequency optical fiber acceleration sensor newLight FS65
Based on fiber Bragg grating (FBG) technology and the newLight series of optical fiber sensors, the acceleration sensor FS65 is a high-precision vibration sensor that measures acceleration at frequencies from 0 to 50Hz. This accelerometer is ideal for a variety of monitoring applications involving low-frequency vibrations, such as vibrations due to loading of civil engineering structures or vibrations of surrounding cables. Multiple accelerometers can be used to simultaneously measure vibration along different axes.
■Features
1. Safe and robust
・Constructed of passive components and a robust IP68 package, allowing use in explosive atmospheres, high voltage areas, and strong electromagnetic fields.
・Suitable for adverse conditions such as poor environments, humidity, and salt content
2. Variety
・Multiple accelerometers can be connected in series to measure acceleration in 2- and 3-axis directions.
・With dual outputs for series connection
3. High sensitivity
・Sensitivity linearity and excellent flat characteristics in all frequency ranges
・High-precision measurement even for highly strained materials
