Industrial Grade Bearing and Machine Sensor – Temperature and Vibration, Wireless

Leap Sensors are specially designed to easily adapt to your specific needs. If this isn’t exactly what you need, please contact us.

Specifications

The Leap Bearing sensor reports temperature and vibration on the axial (parallel to shaft) and the radial (perpendicular to shaft) directions.  It uses a male-to-male adapter to conveniently mount in the existing grease zerk threaded hole – or to any machine surface.

Standard Monitoring Scenario:

• Sensor wakes up every 15 minutes and takes sensor readings and transmits them.
  • Temperature alerts are typically set based on normal readings.
  • Vibration is sampled at 5 KHz on 3 axis for a few seconds in the range of 0 to 8Gs.  The X, Y, and Z axis are converted to axial (parallel to shaft) and radial (perpendicular to the shaft) readings.
    • The data is edge-processed on-board the sensor using proven methods where a change in trend is indicative of an impending failure.
      • The Motor Monitor output are: RMS Acceleration, RMS Velocity, and Peak Acceleration
        • Each of these readings is calculated for the radial and axial direction.
        • Any increase in these values indicate a bearing or machine is functioning differently and likely has a problem.
        • The RMS Acceleration weights the higher frequencies
        • The RMS Velocity weights the lower frequencies.
        • The Peak Acceleration will detect serious impact forces such as bearing defects and chipped gear teeth.
        • See screen-shot above for data output.

Optional Bulk Accelerometer Raw Data Download for FFT Analysis

• Optional bulk data download sends ~20,000 accelerometer readings on each axis so the FFT analysis can be done off-line.
• This mode requires significantly more battery power and is typically done once a week or once a month.

This wireless sensor is ideal for monitoring:

• Bearings
• Gearboxes
• Motors
• Machines
• Grinders
• Blowers
• Compressors
