GD-3134E Cable Testers & Cable Identifier
GD-3134E is a high-performance underground metal pipeline detection system composed of signal transmitters and receivers. It can be used for path detection, pipeline survey and depth measurement of metal pipelines and underground cables. It can carry out uniqueness identification with a variety of selected accessories, as well as pipe insulation damage and the search for some types of cable faults.
● Compass display: intuitively displays the pipeline location and left & right directions.
● Tracking true and false prompts: current direction measurement, tracking correct error prompts, eliminating line interference (some frequencies).
● Depth and current measurements, can display the signal strength historical curve.
● Fully digital high-precision sampling processing: stable and reliable, ultra-high sensitivity, narrow receiving passband, strong anti-interference ability, can fully suppress the power frequency and harmonic interference of adjacent running cables and pipelines.
● Running cable detection: high-performance transmission clamps, maximum coupling output signal to the running cable.
● Cable/pipeline identification: Flexible clamps (optional) are easy to use and clearly give identification results; stethoscopes (optional) can be used when it is not convenient to use clamps.
● Ground fault finding: HV booster (optional) boosts the maximum output voltage to 1000V, uses the A frame (optional) to locate the ground insulation breakage points of the pipeline, no need to adjust zero. The arrow indicates the direction of the fault point.
● Multiple detection frequencies: active detection and passive detection.
● A variety of signal output of the transmitter: direct connection output, clamp coupling output, radiation induction.
● High power output of transmitter, multiple output adjustable, automatic impedance matching and protection.
● Built-in large capacity lithium ion battery group, it will automatic shutdown undervoltage or long time no operation,
● Rugged case, light and portable.
