can be seen during mill start-up, but in normal operation the CO concentration is in the region of 10 ppm. Millwatch analysers offer two independent alarm points, so an alarm level can be set at 300 ppm during start-up, and at 50 ppm for normal operation. Each plant’s operating parameters will eventually determine the proper levels of the dual alarms to provide the proper notifications while ...
