Q: How does Loop Scout work?A: More than 100,000 control loop datasets were sampled from Loop Scout's database of more than a quarter-million loop analyses. Honeywell used them to develop reliable, actionable, diagnostic metrics for oscillation detection, loop performance classification, and valve stiction. Real-time customer feedback ensures that the accuracy and precision of these metrics will continue to increase with time. In every customer comparison, Loop Scout's valve stiction algorithms produced more reliable results than off-line invasive tests.
Q: In what ways can Loop Scout be used?A: It can be used to analyze the most critical loops automatically every day, or it can be used to analyze a single loop after it has been repaired to see whether its performance has improved.
Q: How does Loop Scout centralize monitoring through use of the Internet? A: Loop Scout reduces the total cost of ownership by minimizing on-site software configuration, training, and maintenance costs. It also ensures that analysis results are consistent, accurate, and precise. It also facilitates cross-unit/cross-site performance benchmarking.
Q: What performance metrics does Loop Scout use?A: Loop Scout gives each loop a numerical score and a performance classification, ranging from excellent to poor. These evaluations enable performance benchmarking, aggregation, prioritization, and tracking—making collaboration with management, operations, and maintenance stakeholders more straightforward and objective.
Q: What is the financial impact of using Loop Scout?A: At one chemical plant, engineers estimate that Honeywell's approach to managing control loops contributed to a 2.3 percent increase in production that was valued at $1.7 million per year. Engineers at a major paper company use Honeywell Loop Management Services to trim up to 75 percent of unnecessary control valve repairs and prevent incidents that could cause future downtime.
Q: In what industries can Profit Loop be used?A: Customers include paper companies, oil refineries, chemical plants, alumina refiners, and other process manufacturing businesses.
