HZ-4000A Full-frequency Underground Cable And Metal Pipeline Detector

Scope of Application

HZ-4000A full-frequency cable 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.
