Answer Posted / r.k
the concept of 4-20 mA & -ve voltage in vibration are
totaly different.The proximitty probes by the Bentley
Neveda and the Proximitter works on -ve bias volatge as it
made conventionaly.the devices which transmit the signal as
AC&DC Voltage depends upon measurement with less
trasmission loss to the Input Module.Formation of eddy
current w.r.t vibration is proportional to the changes in
voltage which is measured by the system.
