Industrial Grade Wireless Motor Sensor – Vibration and Temperature Module

Wireless Motor Sensor – Vibration and Temperature Module Specifications

This module is mounted to the machine being monitored and sends vibration and temperature data over the CAN cable to the wireless transceiver node.

• 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 module using proven methods where a change in trend is indicative of an impending failure.

Wireless Motor Vibration Sensor Specifications

• Mount with the provided magnet or other mounting options.
• Vibration sensor is connected to the Leap sensor transceiver node via an industrial CAN cable.
  • Long cables (if needed) are possible between the sensor and transceiver node.
• Multiple vibration modules (up to 6) can be connected to the transceiver node by daisy-chaining the modules on one industrial CAN bus cable.
• 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 – friction, rubbing, grinding
  • RMS velocity weights the lower frequencies – misalignment or fatigue, unbalance, belt issue, poor mounting
  • Peak acceleration will detect serious impact forces such as bearing defects and chipped gear teeth.
  • Crest Factor – Instability usually from impulses
• 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.
  • Samples are taken for 3 seconds.
  • RMS acceleration, RMS velocity, and peak acceleration are transmitted.
  • On-board temperature readings are taken and transmitted along with vibration analysis.
• 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.
• Mounting options
  • Standard mounting option is a strong magnet mount to stick to the metal surface of the motor or other vibrating equipment.  (LP-1V09)
  • Flange mount enclosure option for screwing, bolting, or gluing to surface of equipment. (LP-1V14)
