FBG Point Sensors - Temperature, Strain, Displacement & Vibration
Discrete FiberStrike FBG sensing elements measuring temperature, strain, pressure, bolt tension, crack displacement, linear and rotary position, and acceleration.
CEL's core range of Fiber Bragg Grating point sensors for temperature, strain and pressure, supplied in many configurations for bonding to existing structures or embedding in new construction.
A patented FBG insert that turns an ordinary structural fastener into a smart fastener, continuously measuring bolt elongation and tension. The insert is fitted into a bored and threaded fastener.
Patent-pending FBG displacement sensors that measure small relative movements between a fixed and a moving reference frame, in one or two axes. Marketed on the FiberStrike site as the FBG Crack Sensor.
FBG-based linear and rotary displacement sensors with configurable mounting and end fittings, available in aluminium or stainless steel bodies for harsh and submersible service.
A fiber optic accelerometer for vibration measurement that can be distributed on a multi-sensor fiber network alongside other FiberStrike sensors. Offered as a drop-in alternative to conventional electrical accelerometers.
