Using a vibration sensor is a good way to determine if an asset is running or not. When an asset is running, the vibration should be at a much higher level than when it is idle. By monitoring the vibration, and setting a threshold at a certain level, it is possible to determine if the asset is running or not.
The following sensors can be used to monitor vibration:
QM30VT1
QM30VT2
DX80NxQ45VA
Ensure to use a compatible radio with the QM30 sensors. The QM30VT2 may also be wired directly to the DXM.
