The solution is to automate…

not only the collection of data but also its interpretation.” 

 

“It has been said, with considerable justification, that a condition-based maintenance policy is of little practical use to a maintenance organization unless it can be automated. Proliferating oceans of condition data have outpaced the limited human resources that can be dedicated to CBM decision making. The solution is to automate CBM – not only the collection of data but also its interpretation.”  (Automating CBM, Murray Wiseman – Living Reliability)

online s200 mbvi systems continuously analyze machinery performance, health, and energy use without the need for sensors affixed to the machine

 

Model-Based Voltage and Current (MBVI) systems are a powerful condition monitoring and diagnostic tool for equipment driven by electric motors.  MBVI systems use the motor as a sensor to identify a wide range of phenomena in both the motor and the driven equipment, in the mechanical and operational domains, as well as electrical. Amazingly enough, MBVI systems can even determine the power consumption associated with your specific machinery faults!

 

 

 

 

MBVI systems are also well suited to facilitate energy surveys.  So if you see energy as an asset or if you want to de-carbonize, then use  MBVI systems to help make your equipment more energy efficient.

portable P100 mbvi systems use the motor as a sensor to automatically diagnose mechanical and electrical faults in both driver & driven components 

 

MBVI systems measure the voltage and current drawn by the motor, and do not need sensors affixed to the rotating equipment itself. These measurements are normally made in the motor control center, avoiding the cost and complexity of mounting accelerometers on each bearing, avoiding costs of cabling, conduit, and junction boxes, and avoiding the risk of mechanical damage to the sensors or having to periodically replace batteries. 

 

 

 

 

Not only is energy efficiency and creating a lower carbon future good PR, it also represents an opportunity to improve energy sustainability and turn energy into a source of business growth.

with MBVI systems you get:

  • Advanced diagnostics of machinery mechanical conditions
  • Electrical fault detection and diagnostics
  • Detection of process-induced effects
  • Full & complete monitoring of limited-access equipment
  • Variable speed equipment RPM detection for diagnostics
  • Accurate differentiation of true electrical (feed) and electro-mechanical phenomena
  • Comprehensive data for energy surveys and efficiency improvements
  • All of the above automatically, continuously, at the edge
  • Quantified energy use associated with your specific machine faults

… But you don’t get to:

  • Periodically change batteries on a bunch of wireless sensors
  • Cause environmental concerns with battery disposal
  • Install gazillions of sensors on machinery throughout the plant
  • Run cabling all over your machines for permanently mounted sensors
  • Install junction boxes, channel selectors, conduit
  • Install wireless networking apparatus and then make special provisions for wireless signal transmission problems
  • Use up network bandwidth
  • Contend with IT security issues
  • Get to pay for cloud services

resolves challenges associated with:

 

  • Inaccessible / Submerged / Remote equipment
  • Equipment in Hazardous Environments
  • Variable speed equipment (e.g., inverter-driven)
  • Equipment operating at varying loads
  • Electrically generated signals
  • Equipment displaying torsional vibration phenomena
  • Most electrical problems
