The Transmitter

The transmitter is the single most important component of the CD42 system, and CDI has worked
hard to deliver the most durable, longest life transmitters in the industry. All of our transmitters
emit a magnetic field that passes through the pipeline and is received on the surface by our CD42-
GP antenna and passed on to the CD42-R receiver unit. CDI‟s two most common transmitters are
the CD42-T1 and the CD42-T2 (both of which are available for rental or purchase). The main
difference between the CD42-T1 and the CD42-T2 transmitters is simply signal strength; the "T2"
is 6.5 times more powerful than the "T1". This allows the CD42-T2 transmitter to work in larger
and deeper pipelines than the CD42-T1.
