Supersonic distance sensors enable precise and non-contact distance measurement to the heading face in pipe jacking with open face shields.
In order to observe the procedure of controlled excavation and to prevent the excavation going ahead of the shield the SDV Ultra Module can be added to the SDV system.
The use of SDV Ultraminimizes the risk of collapses at the surface!
The Supersonic distance sensor will be installed in the machine can and continuously measures the distance between machine can and heading face. As soon as the distance exceeds a predefined value a warning will be given to the operator.
