Vibration Sensor Node (SD-VSN-2)
The heart of the SmartDiagnostics® system, Vibration Sensor Nodes are at home in the most inaccessible, inhospitable corners of your facility, monitoring your machine health quickly and accurately.
What is new with VSN 2.0?
Vibration Sensor Nodes Version 2.0 have twice the range, higher sampling frequency, and are two and a half times more robust than before. The sensors can easily transmit a higher density of data using DARTwireless™, and can be powered with either a battery or an energy harvester. In a layout that can be configured for any plant or environment, as many as 100 sensor nodes can now send vibration data to each receiver. The sensors can be tuned to transmit data on the frequency you select, and monitoring bands can be customized to alarm levels that you choose, ready to caution or warn you immediately when frequency rises to a level you specify
SmartDiagnostics® can predict failure before it occurs, saving money spent on unnecessary replacements and extending machine life. At the same time, energy costs are reduced, as cleaner running machines are more efficient.

The VSN is designed to be very energy efficient so that it can operate continuously for many years when powered by a 3.6 Volt battery or virtually indefinitely on a harvester.
The actual amount of power consumed (and therefore the effective battery life) is dictated by two factors:
- The frequency at which the sensor sends a heartbeat ping to the PRN, and
- The frequency at which the sensor collects and transmits vibration data to the PRN.
The heartbeat ping takes very little energy so the primary driver of battery life is governed by the vibration data collection frequency which you configure based on your business needs. The graph below illustrates how battery life varies with changes to collection frequency assuming the sensor heartbeats every four seconds.
Federal Communications Commission Compliance ‒ FCC Class B Device Statement The radio equipment in the SmartDiagnostics Receiver Nodes and SmartDiagnostics Sensor Nodes has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of FCC Rules.
