Wi-SOS 480 Tilt 90

The Wi-SOS 480 Tilt90 provides measurements of changes from the vertical level, either on the ground or in structures. This makes them key sensors to monitor inclinations, movements and differential settlements of slopes or infrastructures.



Tilt90s can be applied to vertical structures as columns, piers, pylons, facades or retaining walls to track changes in inclination and detect differential settlement. They can also be installed to verify over time the geometry and stability of tunnels, railway tracks (cant. twist and vertical alignment) or bridges decks. Tilt meters are also used extensively in monitoring landslides, embankments and mines.
The Tilt90 wireless sensors are now available with an external antenna for full range capabilities or with an internal antenna for applications such as railway tracks where it’s important to minimise the potential risk for external parts.
The Tilt90 has an extremely accurate tri-axis sensor with an extended range of up to 90 degrees. This provides additional flexibility and multiple orientation options during installation.

Case Studies

M6 Junction 10

Walsall Council is working in partnership with Highways England to improve Junction 10 of the M6.
As a busy route between Walsall and Wolverhampton, the junction is often heavily congested. This impacts on local residents and businesses, and has reduced the attractiveness of the local area for investment, including the nearby Black Country Enterprise Zone.
Plans include the widening and redevelopment of two bridges and improvement of the junction.
Traffic management was required to access the locations and potential weather effects on the slopes could have made in-situ data reading difficult. As the piezometer installation was split across both sides of the carriageway, data download could also have been very time-consuming.
Selection of a wireless system avoided any impact from these site-specific problems. The client was impressed with the range of the system even when the nodes were housed inside locked upright security covers.

Mersey Gateway Project

The Mersey Gateway brings much-needed traffic relief for the existing Silver Jubilee Bridge and leads the infrastructure investments required to deliver regeneration of Halton and the North West.
More than 80,000 vehicles use the Silver Jubilee Bridge every weekday – ten times the number it was originally designed for. This extra traffic puts the congested and ageing Silver Jubilee Bridge and the resilience of the regional road network under severe pressure.
The new bridge is designed to carry up to six traffic lanes forming part of a new and improved high standard road (9.5km long) connecting north Widnes and Merseyside with Runcorn and the national motorway network in north Cheshire.
The design of the new Mersey Gateway Bridge is based on a cable-stay structure similar to the second Severn Crossing, but with three towers. It will be 2.3km long with a river span of 1km. The main bridge deck will be made from reinforced concrete and the spans will be supported by steel cable stay.

River Humber Gas Pipeline Replacement Project

Work has been carried out on a £100m project to create a tunnel under the River Humber to carry one fifth of the UK’s gas supply to millions of homes.
The three-mile tunnel houses a new gas pipeline running between Goxhill in North Lincolnshire and Paull in East Yorkshire and was expected to take a year to build. National Grid needed to replace the current pipeline, which is in a trench just below the river bed and is at risk of being exposed by the tides.
The crown of the TBM passed 7m underneath an existing in-service gas pipe, approximately 10” in diameter and a few hundred meters from the reception shaft on the Paull side. On this existing gas pipe in-service, three spots were monitored for changes in strain as the pipe falls in the zone of influence of the TBM.
