Radiodetection Bendi Sonde (512Hz) | Articulated Pipe Transmitter | 6m Detection Depth
The Radiodetection Bendi Sonde is a specialized, three-segment articulated transmitter engineered to overcome the limitations of rigid sondes in complex pipe networks. Its flexible design allows it to navigate through 90-degree elbows and P-traps that typically block standard equipment, making it an essential tool for sewer and utility inspections in challenging geometries.
How does the articulated design improve utility locating?
The three-segment articulated body allows the sonde to 'snake' through tight corners and 90-degree bends common in cast iron and non-metallic sewer systems. This articulation prevents the device from becoming wedged in pipe junctions, ensuring continuous tracking across complex utility layouts.
Why is 512Hz the preferred frequency for this sonde?
The 512Hz frequency is optimized for maximum signal penetration through dense materials like cast iron and deep soil. This low frequency experiences minimal attenuation, allowing for accurate detection at depths where higher frequency signals would be lost.
What is the maximum detectable depth of the Bendi Sonde?
This sonde provides a powerful locating signal for depths up to 6 meters (20 feet). It is powered by a single AA alkaline battery, offering a typical operating life of 15 hours during field use.
