m20 shaft power monitor
The Emotron M20 offers reliable, repeatable results for monitoring and protecting machines and processes against abnormal conditions. The M20 reduces overall maintenance costs by monitoring motor power to eliminate potentially hazardous conditions. With over 500,000 units installed worldwide, it's easy to see why the M20 is the world's most trusted motor monitoring solution.
Low-cost installation and zero maintenance
Using the motor as a sensor eliminates the need for external sensors and extra cabling, and no holes need to be made in pipes. The result is increased reliability and reduced investment, installation, and maintenance costs.

Shaft power monitoring vs. the competition
Unlike Amp / Current monitors, the M20 Shaft Power Monitor reliably protects motor driven equipment from abnormal process conditions such as pump dry run or jamming of a conveyor. In addition to providing inexpensive overload and underload protection, the M20 also provides process optimization and load control capability. Typical applications include conveyor monitoring, pump monitoring, and grinder monitoring.
The M20 achieves accurate and repeatable results by using a patented algorithm to achieve true shaft horsepower, which enables the M20 to provide protection against conditions such as:
- Loss of load
- Misplaced parts
Key Features of the M20
Unique Shaft Power Monitoring
The Emotron M20 immediately detects over- and under load due to, for example, a pump running dry or a crusher jamming. A unique technique to calculate shaft power results in an accurate and reliable supervision across the whole load range.
Enter your settings in three seconds
The Emotron M20 uses a unique 'Auto Set' feature that allows four protection set points to be established in just three seconds. By pressing 'Auto Set' during normal operation, the warning and stop levels are calculated automatically on the basis of the actual motor load measured. If desired, these levels may also be adjusted, independently of one another.

high accuracy with scalable output signal
A unique feature offers high accuracy also in the event of very small load variations. An analog current output signal can be used to scale the machine load to the actual working range. The signal can be used as an input to indicating instruments, controllers, or PLCs.
Accurate monitoring whatever the motor load
The Emotron shaft power monitoring technology offers very accurate, reliable, and cost-efficient supervision of electric motor-driven processes. It was patented in 1979 and since then has been the basis for our shaft power monitors as well as a unique integrated feature in our AC Drives and Soft Starts.
