XHGX507 underground cable pipe locator is mainly used for cable fault location, cable identification, cable path and depth measurement. It can complete tasks that could only be accomplished by a few sets of instruments in the past.
Working principle
The underground cable pipe locator is designed based on the electromagnetic induction method and the application of the communication principle.
1.The electromagnetic signal is generated by the transmitter, and the signal is transmitted to the underground cable under test through different transmission connection methods.
2.After the underground cable induces the electromagnetic signal, an induced current is generated on the cable, and the induced current propagates along the cable to the distance.
3.In the process of current propagation, electromagnetic waves are radiated to the ground through the underground cable. When the receiver detects on the ground, the electromagnetic wave signal will be received on the ground above the cable.
4.The position, direction and fault of the underground cable can be judged by the change of the received signal strength.
Features
●The large-screen LCD displays the signal strength, and the bar, arrows and voice prompts make it easy for the operator to judge the underground position of the cable and the fault point. One person can do it all.
●All-digital design, clear large-screen LCD graphic display and reliable positioning
●Portable and lightweight, easy to carry
●Built-in rechargeable battery
●Built-in ohmmeter to measure cable loop resistance
●Can be used to detect insulation faults up to 2MΩ to ground
●With backlight function to adapt to night operation
●Built-in ohmmeter to measure cable loop resistance
●Display cable depth and current
Main components
