Reason for setting at 10 volt is as we know proximitor allows probe to work from 2 volt to 18 volt.
Bently nevada vibration sensor working principle.
Its products are used to monitor the mechanical condition of rotating equipment in a wide variety of industries including oil and gas production hydroelectric wind hydrocarbon processing electric.
It was quite literally based on which components were the least expensive when the technology was originally introduced 5.
Proximity transducers use eddy current principle to measure the distance between the probe tip and the surface to be observed.
Gap voltage of bently nevada vibration probe is usually set at 10v.
The proximeter generate a low power radio frequency rf signal.
So voltage difference of 2 to 10 and 10 to 18 is 8 volt.
To check the characteristics and healthiness of vibration probes make.
It is capable of both static position and dynamic vibration measurements and is primarily used for vibration and position measurement applications on fluid film bearing machines as well as keyphasor and speed measurement applications.
A design of displacement sensor manufactured by the bently nevada corporation uses electromagnetic eddy current technology to sense the distance between the probe tip and the rotating machine shaft.
Proximity transducer system provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface.
Bently nevada principle.
Bently nevada vibration probes functional testing.
Eddy current principle keyphasor is an electric pulse or trigger which is derived from a point on a rotating shaft it serves as a zero phase reference for determining where imbalance is on a rotor.
The sensor itself is an encapsulated coil of wire energized with high frequency alternating current ac.
We hope this video will help you subscribe power p.
The magnetic field produced by the coil induces eddy currents in the metal shaft of the.
Hence it has remained 2.
Vibration sensor working principle pdf viewer.
The keyphasor signal is a once per turn voltage pulse provided by a transducer normally an eddy current proximity measurement.
Helooo friends in this video we explain why keyphasor installed in turbine its importance how it work.
