Abstract

PURPOSE: This device is used for early detection of piping systems wrapped with insulations, wherein multiple points are kept constantly monitored by utilizing the large changes in the time constants determined by the electrostatic capacities and resistors formed by the inside piping and the electrodes provided on the outside of the insualtions.
