In Vibration Monitoring System -24V DC is using to Proximity sensor(Bently Naveda).
Because PNP transistor is used in this proximity sensor.The PNP transistor bsae voltage is negative 24v supply.That's why -24v DC supply is using.
When the probe is in air it will have no induced voltage
so all -24 voltage without induced voltage will return back.
