Radiodetection Sewer Sonde

The Radiodetection Sewer Sonde is a heavy-duty 33kHz transmitter with an 8-meter (26ft) depth range. Measuring 64mm in diameter, it is designed for large pipes and deep excavations. It features a robust waterproof casing and is powered by a single PP3 battery for long-range utility tracing.

Heavy Duty Structural Shielding: Encased in a thick high-impact housing designed to bounce off internal pipe walls and masonry joints.
High-Power Transmitting Range: Pushes locating signals through deep clay or cast-iron piping setups down to extreme sewer levels.
optimised Weight Balance: Weighted carefully to prevent rolling or tumbling inside moving water flows during pipe tracking operations.
Long-Life Battery Chamber: Features an efficient power draw system to maximize runtime during slow, complex mainline surveys.

Full Description

When standard sondes lack the power to reach the surface, the Radiodetection Sewer Sonde is the professional choice for deep-site surveys. Its larger 64mm diameter allows for a more powerful internal antenna, capable of pushing a 33kHz signal through up to 8 meters of ground cover. This makes it indispensable for groundworkers and drainage contractors working on deep-level municipal infrastructure or major civil engineering projects. The unit is built to withstand the high-pressure environment of active sewer mains, with a rugged housing that is waterproof to 2 bar. It features a standard M10 male thread for connection to heavy-duty rods or can be floated down a line using a specialised "poop" float. For contractors using a C.A.T4 or RD8200 locator, the Sewer Sonde provides a clear, high-amplitude signal that ensures pinpoint accuracy even at its maximum depth, reducing the risk and cost of deep-trench errors.

FAQs

Can we hire this unit for short-term projects?

Yes, the Radiodetection Sewer Sonde is available for flexible short-term or long-term hire, providing a cost-effective way to trace deep drainage systems.

What is the primary function of the Radiodetection Sewer Sonde?

The Sewer Sonde is a robust, battery-powered transmitter inserted into non-metallic sewer lines, stormwater drains, or ducts, allowing its path to be tracked from above ground using a locator.

What frequency does this sonde transmit?

It operates on a standard 33kHz frequency, making it fully compatible with most cable avoidance tools and precision locators, including the Radiodetection CAT4 and RD8200 series.

How does this model differ from the Standard Sonde?

The Sewer Sonde features a heavier-duty, highly resilient casing and is weighted to keep the transmitting antenna oriented correctly while traveling through high-flow fluid environments inside waste pipes.

What is the maximum depth range of the Sewer Sonde?

When paired with a compatible precision receiver, the signal can be accurately detected and depth-measured down to approximately 8 metres deep.

What battery type does it use and what is its operational runtime?

The sonde is powered by a single standard AA alkaline battery, providing approximately 15 hours of continuous transmission time on site.

How do you connect and push the sonde through a sewer line?

It comes equipped with an M10 male threaded connector, allowing it to screw directly onto standard drainage rods, flexitraces, or heavy-duty inspection camera snakes.

Can it be used to pinpoint major structural collapses or pipe blockages?

Yes, by pushing the sonde until it stops against an obstruction, an operator can pinpoint the exact excavation location and depth from the surface.

How do you turn the sonde on and check its operation?

Inserting a fresh battery and tightening the casing cap activates the signal; you then hold a locator near the unit to confirm a strong signal response.

What maintenance is recommended after recovering the unit from a sewer?

Thoroughly wash the casing with clean water, clean any grit from the threaded cap and rubber O-ring seal, and remove the battery to prevent storage corrosion.
