GENERAL DESCRIPTION
The 3014X Electromagnetic transmitter is an ATEX certified EM transmitter that can be used
for pig tracking and location functions. The transmitter operates effectively in buried pipelines,
pipelines carrying gas and in pipeline bundles where acoustic transmitters are either less
effective or ineffective.
The transmitter emits a 21.8Hz signal and an inherent EM null spot is detectable when the EM
receiver antenna is at 90 degrees to and pointing at the centre of the transmitter allowing
centimetre accurate positioning of a pig.
The transmitter can be changed between two pulsing transmission rates via an easily
accessible slide switch inside the transmitter.
The transmitter is configured for use with Lithium batteries only. Lithium batteries provide a
significant improvement in battery lifetime and operation particularly at temperature extremes.
A non-ATEX version of the transmitter can be manufactured with specially designed endcaps
which allow fitting of pigging discs directly to the transmitter - the transmitter itself becomes
the pig body. This dramatically increases the received EM signal because it no longer needs to
propagate through an additional pig body as well as the pipeline.
Parameters such as lifetime, pulse rate, frequency, and output level can be customised during
manufacture, please contact Online Electronics Ltd for more details.
