APPARATUS FOR SIMULTANEOUSLY PERFORMING DCVG AND CIPS DETECTION WITH A CIPS INPUT AMPLIFIER, A DCVG INPUT AMPLIFIER AND AN A/D CONVERTER FOR DEFECTIONS OF PIPE LINE

摘要

PURPOSE: An apparatus for simultaneously performing DCVG and CIPS detection for defections of a pipe line is provided to solve an inconvenience when exchanging equipment by simultaneously processing DCVG and CIPS electrode signals. CONSTITUTION: A detection apparatus(10) includes a detection value input section(101), a CIPS input amplifier(102), a DCVG input amplifier(103), an A/D converter(104), a monitoring circuit(106), an RS-232 converter(107), a power supplying section(108) and a control unit(105). A CIPS electrode rod(40a) and a DCVG electrode rod(40b) are connected to the detection value input section(101). The CIPS electrode rod(40a) and a DCVG electrode rod(40b) output CIPS-DCVG electrode signals to the CIPS input amplifier(102) and the DCVG input amplifier(103) depending on states of switches(SW1,SW2).
