RDP offers cost effective means of monitoring deflections in tunnels

Movement and deflection in tunnels can be effectively monitored using a range of water-resistant LVDTs developed by measurement specialists RDP Electronics Ltd.

Concrete and steel lined, or hewn rock, tunnels can be subject to movement and deflections due to the overlying rock strata. In areas of geological or seismic activity there may be a greater need to monitor movements, which may foretell damage or even collapse of the structure. Transducers to provide accurate response in what is typically a wet and dirty environment usually calling for long cable runs can be met by special water-resistant RDP LVDTs with 4 – 20mA analogue output. Pinned to the tunnel walls an installation may involve tens, or even hundreds of LVDTs with cable runs of 100m or more which is made possible by using these analogue devices.

Further information and guidance concerning transducers for use in tunnel wall monitoring applications can be obtained from the RDP engineering support team on 01902 457512.
