By detecting abnormal conditions, the M20 Shaft Power Monitor is able to drastically reduce downtime and eliminate equipment failure before they occur. The M20 uses a patented algorithm, so that unlike amp / current monitors, the M20 achieves a linear and precise reading of true shaft horsepower. This allows the M20 to reliably protect motor driven equipment from abnormal process conditions such as pump dry run, dead head, closed valve, and cavitation. In addition to providing inexpensive overload and underload protection, the M20 is also compact and DIN-rail mountable, so that it may fit within any electrical cabinet.
