The 360 Multifunctional Underground Pipeline Detector consists of a transmitter, a receiver and accessory for the positioning of underground pipeline routing, buried depth measurements and long distance tracking, and the measurement of pipeline fault points. 360 multi-function underground pipeline detector using a multi-coil electromagnetic technology to improve the accuracy of the pipeline positioning depth and target pipeline identification capabilities in the pipeline-intensive areas can also accurately track the target pipeline and positioning. Therefore, 360 multi-functional underground pipeline detector in telecommunications, China Netcom, mobile, China Unicom, Railcom, electricity, water, gas, geophysical, petrochemical and municipal industries have been widely used.
The 360 Multifunctional Underground Pipeline Detector offers a wide range of optional accessories, which increases their use and extends their range of applications.
1, the determination of underground pipeline routing
2, the determination of underground pipeline depth
3, multi-pipeline case of the target pipeline identification
4, detect and locate the pipeline insulation fault point
1, the use of advanced signal processing technology, integrated circuit components to achieve excellent test performance.
2, a variety of measurement signals to send:
(1) injection method: for the injection point of the pipeline.
(2) clamp method: for the test line has a section exposed, easy to clamp the clamp line.
(3) induction method: for no injection point or no exposed pipeline.
3, a variety of measurement frequency: 480Hz, 7.7KHz, 31KHz and 61KHz four active frequency and power cable 50Hz passive frequency; the user can choose according to the different environment (need special measurement frequency in the order contract Bright).
4, to improve the efficiency of the test different positioning mode and function:
(1) Peak mode: The position of the route is determined by measuring the maximum value of the signal.
(2) valley mode: by measuring the minimum value of the signal to determine the location of the route.
(3) routing orientation: intuitive, quickly indicate the direction of routing.
(4) Insulation fault measurement (FF): Measure and locate the fault point caused by deterioration of the pipeline insulation.
(5) Stethoscope: through the auscultation from the many lines to identify the signal loaded by the pipeline.
5, auxiliary functions:
(1) Receive Gain Auto Adjustment: Automatically adjusts the gain of the receiver to make the receiver in an optimized state, eliminating the need for manual adjustment.
(2) sound function: the receiver through the tone changes intuitively reflect the measured signal size.
(3) pipeline state detection: the transmitter in the injection mode, the first test of the pipeline insulation resistance, residual voltage, and then apply the signal to the target pipeline. When the insulation resistance on the pipeline is small (near the ground short) the transmitter will automatically exit the mode, when the residual voltage is large when the transmitter alarm, the operator should immediately stop the signal load, turn off the transmitter.
(4) battery power detection: the battery power of real-time detection, when the battery is low to the protection value will automatically alarm shutdown.
(5) power-saving features: the transmitter boot about 30 seconds without other keys, the receiver boot operation, if 10 minutes or so no other press the key, the machine will automatically shut down to save battery power.
