Emerson has launched a low-cost upgrade for electrical heat-tracing systems with its new Nelson AXPC100-CM-GP and CM-GP microprocessor-based digital controllers, engineered to accurately control, monitor and maintain the process temperatures of industrial pipes or tanks in ordinary (non-hazardous) locations. Ideal for replacing aging electro-mechanical thermostats, the controllers achieve cost savings by eliminating the need for several components with a design that integrates sensor monitoring, ground fault leakage detection, and remote alarm contacts into a single enclosure.
