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


Coming Soon

This unique Leap wireless sensor can install in the threaded grease zerk hole in bearings.  Remove the grease zerk, install the sensor, then re-install the zerk back into the sensor. Grease guns may be used to continue grease the bearing using the zerk mounted on the Leap sensor.

Mounting adapters also facilitate easy installation on any type of machine.

Accelerometer readings (in all 3 axes) are taken at 5 KHz, then edge-processed into the top predictors of failures.

Temperature and 3-axis vibration sensors are mounted in the stainless steel base.

Send text, email, and phone alerts when temperature vibration limits are exceeded. Data integrates easily into PLCs or other plant monitoring software.

Bulk accelerometer reading downloads are also available as an option.

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.
