Two probes bury ground steel pipeline leak detection device

Two probes bury ground steel pipeline leak detection device. Can solve prior art and exist functional poorly, operation process needs two people adopt to accomplish and cause the manpower extravagant at least, at the dry ground, pave the higher environment of soil resistivity such as road surface in detectivity low to and equipment easily receives the problem that the electromagnetic signal interference leads to the wrong report. The probe is connected with conducting rod one end, and the conducting rod other end is connected through soft wire and electric signal reception machine, and the conducting rod is fixed in insulating probe, the amplifier circuit who is connected with soft wire is drawn together to electricity signal reception press packed bale, and amplifier circuit and filter circuit are connected, filter circuit and frequency -selecting circuit connection, and frequency -selecting circuit and AD conversion circuit connection, AD converting circuit is connected with the display screen, amplifier circuit, filter circuit, frequency -selecting circuit, AD converting circuit and display screen are connected with the battery, and the display screen is established on the electricity signal reception machine up end. Excellent performance, with low costs, operation and simple to use, safe and reliable and practicality are strong.
