I have to measure bearing block vibration by using loop powered transmitter.
Rotating speed of the bearing block is around 300 to 400 rpm of continious opration.
I choose meritx vibration transmitter model no: ST 5484E.
In this model they offer scale range of peak(pk) and rms value.
Kindly...
Could you tell anyone which duty motor is suitable for VFD application. Whether S1 or S9 duty. Motor to drive the load of axial flow fan in aircooler application in oil and gas industry.
