Distributed Tilt Monitoring
Tilt Monitoring
The Osprey Tilt String (OTS) is a high-precision distributed tilt monitoring system designed for vertical and linear assets
With up to 150 micro-tilt sensors connected along a single cable, the OTS provides reliable, real-time measurements while simplifying installation and data management.
Its versatile design allows it to be embedded in concrete, installed in trenches, or deployed along railways and retaining walls, making it ideal for a wide range of infrastructure and construction applications.
Features
Versatile Displacement Monitoring
Robust design for the toughest environments, elegantly engineered for precision results.
Low Power
Osprey’s advanced protocol allows us to carry out sophisticated measurements and data processing without compromising battery life. Our low power design offers compatibility with battery operated data loggers without the need for an external power supply.
Easily Modify String Lengths
The Osprey Tilt String can be cut to length or extended using our 12 Bar pressure rated in-line connectors. The string is light weight and easily coiled into a small enclosure to accomodate excess sensors and cable for short term projects, ready to deploy on another project in the future.
User Defined Digital Commands
The digital output means only one signal cable is required to read an array of Osprey Tilt Strings. We offer a selection of RS-485 protocols including ASCII and Modbus RTU, giving you the flexibility to link your system to a wide variety of data acquisition and telemetry devices.
Move With Your Project
The mounting options available with the Osprey Tilt String allow the OTS to be repurposed for any application. Simply unbolt the sensors from one mount and replace with another to suit your next project, making decommissioning and redeployment quick and easy.
How it works
The OTS comprises of a series of high precision, triaxial accelerometers for 360° tilt monitoring at regular intervals.
The digital bus configuration means you have a single data logger monitoring up to 150 devices from an accessible location. This simplifies data management and greatly reduces maintenance costs.
The system is designed for ease of installation, with a number of fixing options specifically catering to a range of monitoring applications. The versatile design allows users to integrate the system to their project in whatever way their imagination allows.
The robust design allows the OTS to be installed conduit free in trenches, boreholes, concrete, tunnels or rail.
Mounting Options
Mounting bracket
For concrete, masonry, steel or wood using anchors, screws, or adhesives for a robust mounting while allowing easy retrieval of the device.
track Clip
For low profile longitudinal settlement profile of rails. Mounted in the web of the rail, safe from rail maintenance operations.
Fixing Straps
For fixing to reinforcement cages, inclinometer casing, access tube etc. for direct embedment applications.
Magnets
For rapid deployment on steel: rail, pipelines, gantries, bridges, tunnels, struts, girders etc.
Weld Plate
For welding directly to steel structures such as sheet piles, props, pipelines or bridges.
Glue plate
For low-profile, rapid deployment and easy, clean removal. Ideal for chemically bonding to steel or concrete.
Rod Mount
Mount the OTS on a GRP rod for secure positioning within a trench, borehole or pile.
