DYNALOG ELECTRONICS LTD.

The use of non-contact systems, using the electrical field radiated by a buried pipeline carried by a low frequency signal, showed promise as theoretically it would enable the user to determine the rate of current loss - and therefore the coating quality and fault location - on pipelines under all surfaces. This became the basis for development of the System.

A new patented multi-coil antenna assembly was developed and this, together with the advanced electronics of the Detector Unit and the computer-controlled output of the Signal Generator, formed the basis for the first production Systems in 1983. Systems are now in use in nearly 40 countries around the world and are supported directly by Dynalog Electronics or through local distributors or technical agents who have been trained by Dynalog personnel, either in their own territory or on courses that the company runs at its own plants. As pioneers in this field, Dynalog has maintained its leadership through a policy of continuous improvement. The 2000 series - a complete re-design incorporating the latest developments in electronics, the results of further research, and feed-back from over 20 years of field experience – was launched in 1995. Now complemented by the latest development, 2010, these instruments provide even greater sensitivity and accuracy, longer battery life, lower weight and stronger housings which can withstand extreme operating conditions.

All controls on the Detector and Signal Generator are through membrane key-pads and large graphic LCDs which display information and 'prompt' messages. Survey reports can be downloaded from the Detector Unit direct to a printer or to a computer for storage, analysis or comparison with previous surveys. has the ability to display and store GPS co-ordinates through its own internal GPS unit.
