© Emotron AB Protection against damage and downtime Emotron M20 Shaft Power Monitor

© Emotron AB Unique shaft power calculation Uses motor as a sensor Increased reliability Reduced maintenance costs Low-cost installation Emotron M20 – efficient protection

© Emotron AB Preventive action saves money Efficient and reliable operation Reduced maintenance costs Short pay-back time Early warning or stop Pump is running dry Scraper blade is damaged Crusher is jammed Load Time Overload stop Overload warning Normal load curve Underload warning Underload stop

© Emotron AB Unique shaft power monitoring Unique monitoring technique Shaft power = Input power – Power loss Accurate value over the whole load range More reliable supervision Shaft power Current Phase angle Input power kW/A/φ° Motor load 100%

© Emotron AB Uses motor as a sensor Uses drive motor as a sensor No sensors or extra cabling No holes in pipes Increased reliability Reduced installation costs Reduced maintenance

© Emotron AB Direct correlation to pump curve Prevents dry-running and cavitation Direct correlation to pump curve Set max. and min. load levels for pump and motor Immediately detects over- or underload Head (mvp) Warning dry-running Warning cavitation Operational area Pump Motor shaft power Operational area Load Flow

© Emotron AB Higher accuracy with scalable signal Unique scalable analogue output signal Machine load scaled to actual working range Reliable monitoring also when small load variations Input to indicating instruments, controllers, PLC Machine load 100% Output signal mA 70% Actual working range 30% Emotron M20 scaled output signal Unscaled output signal

© Emotron AB Low-cost installation Reduced installation costs Uses motor as a sensor No external sensors No holes in pipes Monitors via current transformer No external transmitters Minimized wiring

© Emotron AB Enter your settings in three seconds Unique Auto set feature Set four protection points in three seconds Press Auto set during normal operation Warning and stop levels calculated automatically

© Emotron AB Zero maintenance Higher reliability and reduced maintenance Replaces costly and service- demanding components Solid-state device with no moving parts Installed away from hostile operating area

© Emotron AB Protection to meet your needs

© Emotron AB Pumps Warns or stops the pump Risk of dry-running or cavitation Motor does not drive the pump Low flow, closed valve, blocked pipe etc. Reduced maintenance costs Increased reliability Less downtime

© Emotron AB Mixers Warns or stops the mixer Damaged mixer blade Shaft oscillation Viscosity is right Reduced maintenance costs Increased reliability Less downtime

© Emotron AB Scrapers Warns or stops the scrapers Jamming Damaged scraper blade Reduced maintenance costs Increased reliability Less downtime
