DATA SHEET FS62PSR Patch Strain Rosette SPECIAL FEATURES S High strain and high fatigue resistance Straightforward installation Configurable wavelengths, cable lengths and connector types DESCRIPTION The Patch Strain Rosette is a Fiber Bragg Grating (FBG) based sensor designed to be easily glued to sur faces. It has three FBG at 0º/60º/120º embedded on the same substrate turning it into a robust solution for a straight-forward and uncomplicated installation even for unexperienced users. The FS62PSR is based on the newLight® technology developed by HBK FiberSensing. newLight sensors employ high strength fiber coatings ensuring increased strain ranges, enhanced fatigue resistance and higher measurement accuracy. HBK FiberSensing offers inno vative sensor designs compatible with standard telecommunication fibers. This eases network design and significantly reduces installation time and cost, even when a large number of sensors are multiplexed on the same fiber, sometimes kilometers apart. The technology is completely passive fitting explosive envi ronments, self-referenced (providing measurement long term stability), and compatible with most inter rogators in the market. Combine this with other strain and temperature sen sors from HBK FiberSensing with braided cable. Please contact HBK FiberSensing for support. BENEFITS AND APPLICATION Sensor design Fiber Bragg grating technology Bi-dimensional stress analysis with 0º/60º/120º rosette strain measurement No drift, absolute referenced measurements Extended operating temperature range Immune to electro-magnetic and radio frequency interferences Suited for measuring on curved surfaces Rated for laboratory applications, but also fitting outdoor installation with appropriate protection Passive technology fitting applications in explosive areas Reduced cable requirements with intrinsic multi plexing capability Long distances between sensors and the interroga tors attainable Combinable with other FBG sensor types on the same fiber and same interrogator
