M20 1×100-240/3×100-240VAC Shaft Power Monitor “Emotron”

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
Unique shaft power calculation
Fast and accurate detection by using the motor as a sensor
Increased reliability
No sensors or extra cabling
Single phase current measurement, CTM current transducer option available
Voltage range: 3 x 100-690V and 1 x 100-240V (see appropriate models)
Current range: 0.4 – 999A
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:
Overload
Jams
Loss of load
Misplaced parts
Typical installations include:
Pumps Clarifiers
Fans Agitators
Conveyors Blenders
Mixers Grain Legs
Mills Air Locks
Bar Screens Grit Collectors
