Wireless Vibration and Temperature Sensor, Magnet Mounted – Leap Sensors

SKU: LBI0-1V04 Categories: , , Tag:


The ultra-strong magnet mounts the device node to the equipment in seconds. Vibration and temperature is conducted through the magnet to the accelerometer and temperature sensor.

Ideal for monitoring large gearboxes, bearings, and motors to detect impending failures.


  • Monitors the top predictors of impending equipment failures.
    • Motor vibration monitoring sensor detects maximum and average vibration on 3 axis to detect upward trends or spikes in vibration.
    • Motor temperature monitoring sensor detects over-heating.
  • Fast and easy to install.
    • Magnetic mounts the vibration and temperature sensor in seconds.
  • Standard monitoring scenario: Sensor transmits readings every 15 minutes.
    • Temperature alerts are typically set based on normal readings.
    • Vibration is sampled at 5 kHz on 3 axes for a few seconds in the range of 0 to 8Gs.
      • The data is edge-processed on board the sensor using proven methods where a change in trend is indicative of an impending failure.


Temperature Sensing Specification

  • -20C to 85C standard temperature range.
    • Optional -40C to 200C available with special configurations.
  • Temperature sensor is embedded in the magnet.


Vibration Sensing Specification

  • 3 axis g-force reading taken and edge-processed into RMS acceleration, RMS velocity, and peak acceleration. Any increase in these values indicate a motor is functioning differently and likely has a problem. Each of these readings is calculated for both radial (rotating) vibration and axial vibration (parallel to the shaft of the rotating equipment).
    • RMS acceleration weights the higher frequencies.
    • RMS velocity weights the lower frequencies.
    • Peak acceleration will detect serious impact forces such as bearing defects and chipped gear teeth.
  • G-force readings up to +/- 8 G.
  • Accelerometer operating temperature: -40C to 85C (-40F to 185F)
  • On-board storage for 174,762 sets of 3-axis (x, y, z) g-force samples with 12 bits of resolution.
    • Data is typically processed by a powerful onboard microprocessor using FFT algorithms. Processed vibration analysis is then sent to the transceiver node.
  • Typical sampling and analysis (can be adjusted to each application):
    • Accelerometer is checked every 15 minutes.
    • Each axis is sampled at 5 KHz. (Up to 5 KHz sampling available, if needed).
    • Samples are taken for 3 seconds.
    • RMS acceleration, RMS velocity, and peak acceleration are transmitted.
  • Advanced Fast Fourier Transform (FFT) edge computing available
    • Sensor has a powerful microprocessor and large memory to take vibration samples and process the data at the sensor.
    • Custom edge computing algorithms using FFTs and other sophisticated methods are available.
  • Configurable high G-force event – instant wake-up and transmit function – optional.


Magnet Specification

  • 35 pounds maximum pulling force (on clean steel surface). Holding force is typically less on surfaces that are painted, dirty, or not flat.
  • 180 F maximum temperature (standard product). Magnet is 2.75 x 1.12 X 0.5 inches – mounted to the back of the composite enclosure.
    • 390F magnet option available.
  • For non-steel surfaces or surfaces with poor magnetic attraction (such as electric motor fins):
    • Steel sheet metal interface plates are available that come with expoxy to adhere the steel to the desired surface.
  • Not recommended for non-flat surfaces.
