The Model RF-IT is a highly sensitive device used to test above ground pipeline insulators. The automatic
RF-IT allows the operator to pinpoint the precise contact point. The RF-IT emits an audible beep
and when the operator gets closer to the point of contact the unit starts beeping faster. A sliding scale
LCD meter moves from left to right.
Theory of Operation
The RF-IT works using Radio Frequency. The Radio Frequency signal is applied to one side of a pipe by
one of the two probes. The second probe then receives the high frequency signal. If the received signal
is almost as strong as applied, the pipe is shorted.
The RF-IT has an internal band-pass filter which will filter out all the frequencies above and below
221kHz. This allows taking measurements on pipelines that are under cathodic protection or have
other induced or impressed currents or signals. It is important to note that because the RF-IT uses Radio
Frequency to measure the effectiveness of an insulator, the measurement results can not be displayed
in Ohms. |
