Monitoring control system AFR-9R

industrial

Set point and operation done entirely through the full-color graphic display, enclosure or remote mounted Designed for wide range of horsepower, gas fueled, carbureted rich-burn industrial engines Microprocessor-based controller with nine air/fuel set points Available with either the non-intrusive fuel enrichment strategy or the in-line fuel authority control strategy High-speed full-authority butterfly fuel control valves for quick response time. (available) Proportional solenoid fuel control valves for auxiliary fuel control (available) Map sensor to measure variances in manifold air pressure The AFR-9R is the right choice when searching for the simplest to use load following air/fuel ratio control system. The system is designed to maximize the efficiency of a three-way catalyst by maintaining the proper air/fuel ratio over varying engine loads, speeds, fuel quality, ambient temperatures and barometric pressure. This is done without operator intervention after the initial program setup. The AFR-9R features nine set point targets based on a combination of three RPM settings and three manifold pressure settings and includes three valve default position settings. As your engine’s load and/or speed change, the AFR-9R anticipates (feed-forward control) and corrects the air/fuel ratio to optimize catalyst performance. The system includes the Murphy PV-450 full-color graphical user interface for control functions, monitoring, programming and diagnostic displays. The eight-button display includes comprehensive built-in help files for added operator convenience.
