Pipe Tracing using a Sonde
Non-metallic pipes such as sewers or drains, service
ducts, plastic gas and water pipes are not electrically
conductive and so will not be detectable using a Locator
on the Power, Radio or
All Scan Modes. It is also
impossible to apply a detectable Generator/ Transmitter
signal to the non-metallic pipe or, for that matter, to the
water or gas within that pipe.
If access can be gained into these pipes then a C.Scope
Sonde or Plastic Pipe Tracer should make it possible to
determine their position and route.
Sondes
C.Scope Sondes are small, battery powered, waterproof,
33kHz, 8kHz OR 640/512Hz transmitters that can be
inserted into pipes such as a sewer, drain or cable duct.
Their position can be pinpointed (and therefore the location
of the pipe) by using the Locator switched to Generator
Mode/ Transmitter Mode.
The Sonde is inserted into and then moved along
the pipe to the point at which the pipe needs to be
located. This is normally done by fitting the Sonde
to drain rods. Alternatively, the Sonde can be attached
to a continuous fibreglass duct rodder, jetter hose or
camera inspection system.
The 33kHz and 8kHz General Purpose Sondes can be
used in pipes as small as 50mm in diameter and up to
seven metres deep.
The 33kHz Duct Sonde can be used in pipes as small
as 30mm in diameter and up to five metres deep.
The 640/512Hz Metal Pipe Sondes can be used in Pipes
as small as 50mm in diameter and up to 2 metres deep.
C.Scope are continually developing Sondes for specific
applications. Keep abreast of our latest products via
our website www.cscopelocators.com or your local
distributor.
NOTE
A 33kHz or 8kHz Sonde will NOT transmit a signal through a metal pipe.
