The Osprey Tilt String (OTS) is a distributed tilt sensing array designed for versatility and ease of use. The system comprises a series of tilt sensors, regularly spaced along a single cable bus.

Each tilt sensor utilises a high precision triaxial accelerometer to provide rotational measurement in any orientation to a high degree of accuracy.
The system is designed to be well suited to a broad range of structural and geotechnical applications, either surface mounted on steel, concrete, wood, or masonry, or directly embedded in concrete, grout, or soil.

A variety of mounting options enables rapid deployment in any application, and the system’s single cable bus and low power consumption allows simple connection of large numbers of sensors with a single battery powered digital datalogger. This minimises maintenance requirements and simplifies data management.
