Specification

The FS64TLS — is a robust tilt sensor from the newLight optical sensor line, designed to detect minute angular deviations relative to the vertical axis. Utilizing a dual-FBG push-pull configuration, it ensures effective temperature compensation and stable long-term performance.

Its armored cable and IP65-rated enclosure provide resilience against dust, moisture, and mechanical stress, while its bolted mounting ensures secure installation.

Engineered for structural health monitoring, the FS64TLS is ideal for applications such as retaining walls, bridge foundations, tunnels, and buildings. The sensor is suitable for use in environments with explosive atmospheres (ATEX), electromagnetic interference (EMI), and radio-frequency interference (RFI), making it a reliable choice for critical infrastructure monitoring.

newLight FS64 Tilt Optical Sensor for Measuring Small Angle Variations

Based on the newLight optical sensor line, the FS64 tilt sensor is a ruggedized Fiber Bragg Grating (FBG) inclinometer designed to measure very small angle variations towards the vertical. The sensor uses two FBGs in a push-pull configuration for effective temperature compensation.

It can be used in a large range of monitoring applications such as sustaining walls, bridge piles, tunnels, or buildings. The measurement of tilt in different directions is possible with the use of multiple sensors.

Robust and reusable

Ruggedized packing and electrical passiveness make it suited for potentially explosive atmospheres, high voltage areas, and intense electromagnetic fields
Effective even under aggressive environments and adverse conditions such as humidity and salt

Stable

Effective temperature cross-effect compensation (<3milideg/ºC) by the employment of two FBGs in a push-pull configuration
Fitted for long-term measurements with temperature changes

Compatible

Stress-free connection with other FBG-based transducers and compatibility with most optical interrogators
Cost-effective shared equipment and simpler sensing networks
