The document summarizes the characteristics and technical specifications of the FOT7570 Pipeline & Cable Locator. The locator consists of a transmitter and receiver used to accurately locate, measure burying depth, trace over long distances, and detect insulation faults of underground pipelines and cables. It adopts advanced signal processing and integrated circuit technologies. The transmitter can output signals at various frequencies for injection, induction, and clamping methods. The receiver can detect buried pipelines up to 4.5 meters deep within 5 centimeters of accuracy and has an effective detection range of over 10 kilometers using injection and shorter ranges using other methods. The kit includes the transmitter, receiver, carrying case, manuals, chargers, and optional accessories.

1. Characteristics
 Adopt advanced signal processing technology and latest integrated circuit
 Detecting frequency optional:480Hz,7.7KHz , 31KHz and 61KHz(active )and 50Hz(passive)
 Fault finding (FF)mode: Detect and locate the insulate fault point of pipeline&cable
 Find loading signal on the pipeline through stethoscope from the multitudinous pipelines.
 Automatic control receive gain
 Automatic test insulation resistance and the residual voltage of pipeline and alarm
The FOT7570 Pipeline & Cable Locator consists of a Transmitter, a Receiver and Accessories,
used in the underground pipeline&cable route accurate locating, the burying depth measuring, long
distance tracing, and insulation fault point detecting. We adopted multi-coil electromagnetism
technology on the Pipeline & Cable Locator, enhanced the pipeline&cable location precision for the
burying depend he goal pipeline identification capability, also could accurately carry on tracing and
location to the goal pipeline&cable in the pipeline&cable crowded complex environment.
