【Scope
of Application】
Shengli
SL-480B full-frequency pipeline detector is the preferred equipment specially detecting various kinds of pipelines for oil (gas)
transportation, water supply, drainage, gas, heat, and industry, etc. and
various cables for electricity and telecommunication, etc. used by such
underground pipeline design organizations as professional pipeline detection,
pipeline management and maintenance, municipal administration planning and
construction, power supply, building and construction. It’s also the optimum
replacement for traditional underground pipeline detectors.
【Characteristics】
1.
Adoption of DSP processors, having a higher calculation speed and accuracy;
2.
The orientation function available to indicate the pipeline running, making
location faster;
3.
The 10W broadband transmitter used, applicable to various environments;
4.
The Lithium battery pack used to supply power for both the receiver and the
transmitter, being energy-efficient and environmental-friendly, able to save battery
costs of RMB 3000 to 5000 yuan annually.
【Working
Principles】
The
full-frequency detector detects underground pipelines electromagnetically,
which applies signals to metal pipelines through the transmitter, generates the
piping currents in metal pipelines and the secondary magnetic field around
pipelines, and measures the secondary magnetic field of pipelines on the ground
through the receiver, in order to accurately determine the location, buried
depth, running direction, route and signal current intensity of pipelines.
