Wireless Motor Sensor – Vibration and Temperature Module
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 using proven methods where a change in trend is indicative of an impending failure.
Wireless Motor Vibration Sensor
- Mount with the provided magnet or with threaded stud.
- 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 30) can be connect to the tranceiver 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. (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.
- Optional Magnet Mount Kit
- When quoted, an optional magnetic mounting kit will be included with the quote.
