Arrangement with special prerequisites
Tunnel curvature
The sensors can be used with tunnel curvatures up to the following curve radiuses:
Fig. 5: Fitting sensors on the inner curve wall
Fig. 6: Fitting sensors on the outer curve wall
Tunnel with sound insulation wall
Provide appropriate assembly bases onsite when fitting sensors on a tunnel wall with
sound insulation.
The assembly bases must provide a firm base suitable for reliable sensor fitting.
