Shaft Power Monitors

The Emotron M20 shaft power monitor offers pump protection for positive displacement and centrifugal pumps.  The Emotron M20 utilizes a sensor that detects current from the electric motor.  It is designed to detect overload and underload conditions.  When detecting abnormal conditions the monitor can be programmed to send a warning or shut down the pump.  It is excellent for systems that may experience the following conditions:
  • Dry-Running/Cavitation
  • Inefficiency due to low flow, a closed valve, a blocked pipe, etc.
Emotron M20 shaft power monitors require NO special programming and NO external power supply. They are small enough to fit into a typical motor starter enclosure and can be set in as little as 3 seconds!
