FS64: High Performance Fiber Bragg Grating (FBG) Tilt Sensor

FS64 Optical Tilt Sensor is designed to measure small angle variations towards the vertical. The sensor uses two FBGs in an innovative push-pull configuration for effective temperature compensation.

It can be used in a large range of monitoring applications, such as in slopes and bridge pillars.

Measurement of tilt in different directions is possible using multiple sensors.

Passive

Inherent immunity to all electromagnetic effects (EMI, RFI, sparks, etc)
Electrical isolation

Safe operation in hazardous environments (e.g. potentially explosive atmospheres, high voltage areas and intense electromagnetic fields)

Multiplexable

Connection of a large number of sensors to a single optical fiber
Multipoint measurements

Reduction of installation complexity: much simpler sensing networks and cabling

Reliable

Based on the measurement of an absolute parameter - the Bragg wavelength - independent of power fluctuations

Self-referenced: high quality measurements with long term stability and low losses even in remote sensing

Robust

Innovative sensor design
Ruggedized stainless steel packaging

Enhanced lifetime: even under adverse conditions (humidity, salt, EMF, pressure…)
