Neuron Vibration RMS Wake on Shake

General Description

The Neuron Vibration RMS Wake-on-Shake is a battery-powered, wireless sensor that continuously monitors vibration levels. When vibration exceeds a predefined threshold, the sensor wakes from its low-power state, measures RMS acceleration using its triaxial accelerometer, and transmits the data to the Neuron Cloud.

The device supports a measurement range of 0–12 g RMS with a resolution of 1 mg. It also has a temperature sensor mounted on its magnet, measuring the objects surface temperature over the range -40 to 85C.

The IP67 rated device is encapsulated in polyurethane that provides protection against dust and water ingress, making it suitable for use in harsh industrial environments. Its small size and light weight, paired with its magnetic mount, makes it a very powerful device – ideal for use in predictive maintenance and monitoring of vibration levels on a variety of industrial equipment and machinery.

Principle of Operation

The sensor’s Wake-on-Shake function continuously monitors vibration levels while operating in a low-power sleep state. It samples vibration at 12.5 Hz, and if the measured level exceeds 0.1 g for at least 0.1 seconds, the sensor wakes, waits 0.5 seconds, and then measures both the vibration RMS level and the surface temperature.

RMS acceleration is captured on all three axes with an 80 ms measurement window at a sampling rate of 3200 Hz, providing a usable bandwidth of 1600 Hz.

After a Wake-on-Shake event, the feature is temporarily disabled for 2 minutes to optimize battery life. If no vibration triggers occur, the sensor will still perform a periodic measurement every 5 minutes.

Vibration RMS and temperature data are transmitted to a nearby Neuron Gateway, which forwards the data to the Neuron Cloud for visualization and analysis across assets.

Most configurations are adjustable upon request.

Neuron sensors are ready for use out of the box and will start logging data after registering the sensor in the app. Even though Neuron sensors deliver great range and long battery life, following some simple guidelines for mounting of the sensor and gateway can greatly improve signal coverage and lifetime of the sensor.

To ensure optimal antenna performance and signal strength, the sensor should be placed elevated with some distance to fixed objects. Keep in mind that RF-signals are greatly affected by close metallic surfaces.

For sensors with an external antenna, the antenna should be clear off the metallic surface.

For sensors operating in environments with greatly varying temperatures, care should be taken to avoid putting the sensor in unnecessary stress. Very high or low temperatures will affect the battery life and the signal strength of the sensor. While some sensors must be close to the source of heat or cold, other sensors have external probes which allow the sensor to be placed at a distance.

Fastening
Neuron Vibration RMS is fitted with a strong magnet at the back for easy fastening. If there is non-magnetic surface, PN 422691 Neuron Magnetic Mounting Assembly is a good solution. Epoxy glue can also be used to fasten the sensor to non-magnetic surfaces.
