The S9 MiniSonde is a small 9mm (0.35”) diameter transmitter designed to be inserted into non-metallic pipes or ducts, and enables operators to trace the route of small diameter pipes or ducts and to precisely locate any blockages. The flexibility of the S9 Minisonde allows the sonde to travel around bends or pass existing cables, while durable design and construction helps to protect the S9 Minisonde from damage when travelling around bends or when encountering obstacles within the duct. The S9 MiniSonde is the ideal accessory for small diameter ducts, where flexibility and strength are required.

More and more cables and pipes are being laid in the underground network, making buried utility ducts increasingly congested. Before attempting to insert other cables into an existing duct it is important to know if there is enough space for another cable or if there are any blockages within the duct.


Blocked / damaged ducts

Utility pipes and ducts may become blocked or deformed, both before and while in use. These blockages cause delays due to failed cable insertions, and can even require excavation to clear them - an expensive and time consuming task. 


The S9 MiniSonde is designed to be pushed or pulled into a small buried pipe or duct using the installer’s standard installation kit. By using a Radiodetection locator the operator can follow the path of the sonde as it travels, confirming its route and reducing the risk of damage from local excavations. 


If a blockage is found, an operator can precisely locate the position where the sonde stops from above ground, and evaluate if excavation is required.
