Emotron M20 Shaft Power Monitor

The Emotron M20 shaft power monitor helps you save time and money. It protects your pumps or other applications against damage and detects process inefficiency. Early warnings allow you to take preventive action. Unique features include measuring shaft power output and using the motor as a sensor. The result is reduced maintenance and installation costs, extended equipment lifetime and increased reliability.

Preventive action saves time and money
You can’t afford not to protect your pumps or other applications with Emotron M20. The shaft power monitor offers reliable insurance against process failure and its costly consequences. By immediately initiating a warning or stopping the process, the monitor minimizes production downtime, prevents equipment damage and eliminates unnecessary wear. Preventive maintenance instead of repairing or replacing damaged equipment saves time and money. Payback time is short, in many cases negligible considering the cost of one single production stop. Is it a question of hours, days or weeks at your plant?

Unique shaft power monitoring
The Emotron M20 uses a unique technique to monitor motor shaft power. The result is an accurate and linear motor load value across the whole load range. The shaft power output is calculated by measuring motor input power, sometimes called true power, and subtracting the motor power loss calculated using a unique and precise principle. The shaft power output is indicated on the monitor display in kW or hp, or as a percentage of rated power. Both current measurement and phase angle are used in order to calculate an accurate load value for high as well as for low load levels. This gives more reliable supervision than non-linear methods. A system using current measurement alone would detect load variations only at high motor loads.

Protection – Pre-alarm, alarm and stop before any machine over or under load damage occurs. This increases lifetime and reduces spare parts requirements.

All in one – You will have a readout of the motor shaft power in % of rated power,kW or HP. The analogue output signal can be scaled to the desired shaft power range and used as an input to controllers.

Easy to install – No sensors or sensor cables, meaning fewer components and easier setup and startup. Alarm functions can be set within three seconds at just the push of a key.

Applications

Pumps-Centrifugal pumps, Magnetic drive pumps, Screw and impeller pumps, Mixers, Scrapers, Conveyor systems, crushers etc., machine tools.
