Emotron M20 Shaft Power Monitor – Smart Protection for Pumps and Motor-Driven Equipment

The Emotron M20 Shaft Power Monitor is a compact, high-performance solution designed to protect pumps, fans, and other motor-driven equipment from costly damage and downtime. By using the motor itself as a sensor, the M20 offers accurate and fast load monitoring—with no need for external sensors or extra cabling—significantly reducing installation costs.

Thanks to its unique shaft power calculation, the M20 delivers early detection of both overload and underload conditions, allowing operators to take preventive action before issues escalate. This not only lowers maintenance costs but also increases overall system reliability.

With fully programmable settings, the M20 provides complete flexibility to meet your protection needs. Choose from overload, underload, or both, configure pre-alarms, and set independent response delays. Programmable output relays, a set number of start and reversing attempts, and a wide operating range make the M20 ideal for a variety of industrial applications.
