Abstract: The transmitter of this application provides a tubular body fabricated from an aluminum tube into which is inserted an electrical coil formed from high permeability nickel alloy material which is rolled into coiled sheets then inserted one into the second and sometimes third sheet. A battery is inserted into the nickel alloy tubing formed from these coiled sheets and connected to the electrical coil. Electronics comprising a constant output voltage switching power regulator, a Hall effect sensor, a micro-processor and a MOSFET bridge energize the coil in alternating directions providing a magnetic field capable of detection by the transmitter signal detectors used in the pipeline business. The duty cycle and frequency can also be adjusted through an exterior magnetic force pulse generator to communicate with the microprocessor within the transmitter.
