Identify Possible Motor Abuse or Misapplication 

It is now possible to track motors through the stray flux to confirm potential process problems. If an electric motor is designed to be started and stopped once a day and it is actually being started 10, 20 or even 100 times a day, there is going to be a maintenance problem in the future. With the SST-50 Start/Stop/Timer identify potential process abuse before problems develop.

More Accurately Schedule Maintenance

Schedule maintenance according to length of run time instead of on a monthly, quarterly, or even annual basis. Prioritize motors by duty cycle during outage times to better share work requirements. For example: did that motor really run 200 hours or 2,000 hours?

Multi-motor Processes

Monitor energy usage for projects by run time hours. Examples include irrigation pumps, just how long did that pump run?

SST-50 Start/Stop/Timer

The SST-50 is a rechargeable battery enclosed unit that magnetically attaches to the outside of the motor case and counts each start. It records run time in 6 minute intervals (1/10 of an hour). The display gives the maintenance professional knowledge on duty cycle that motors are operating within.

Benefits of Use

  • Schedule maintenance activities
  • Identify possible abuses
  • Remaining useful life estimates
  • Know which shared process motors are doing most of the work
  • Monitor start/stop and run time on problems motors
  • Troubleshooting - just when did that motor trip
  • Super easy installation - just magnetically attach to outside of motor

SST-50 Technical Specifications

  • Magnetically attached to side of motor or U-Bolt to conduit/base
  • No hook up required, triggers off of stray flux
  • 25 year data retention
  • Zero reset switch for time and starts
  • IP67 Ingress Enclosure
  • Auxiliary input use in low flux situations
  • Solar charge capable
  • Rechargeable battery pack through USB wall wart or Aux

Intended Use

Understand the duty cycle of motors in your facility.

  • Inexpensive/quick way to track run time and starts in electric motors
  • Duty cycle monitoring in multi-motor processes (e.g. 2 sump pumps)
  • ​Maintenance scheduling
  • ​Energy audit
