The CPMS Cathodic Protection Monitoring System monitors above and below ground impressed current cathodic protection systems to ensure that proper corrosion protection is in place and operating at the right levels. The CPMS Cathodic Protection Monitoring System monitors above and below ground impressed current cathodic protection systems to ensure that proper corrosion protection is in place and operating at the right levels.
Part of Moore Industries’ NET Concentrator System® family of intelligent distributed I/O, the CPMS monitors the critical current and voltage levels of one or two transformer rectifi ers used in cathodic protection systems. Each module provides four or eight, fully-isolated analog input channels and four discrete (contact closure) inputs. It “concentrates” this data onto one or multiple communication links, and transmits it long distances back to one or more host DCS, PLC or PC-based control systems.
The CPMS accepts up to four discrete (contact closure) inputs from the monitored system. Using an internal control engine, the CPMS can be programmed with internal set points that relate to normal operating conditions within the cathodic protection system. Should monitored parameters go outside of selected limits, or if power to the cathodic protection system is lost, the CPMS alerts of the unwanted conditions at the control system over the data link.
In addition to operating in a stand-alone mode, the CPMS integrates with any of Moore Industries’ NET Concentrator System’s analog, temperature, discrete and relay I/O modules. When coupled with the ROM (Relay Output Module), relay outputs can control rectifiers using accurate GPS time to facilitate taking cathodic protection reference electrode readings.
