Bently Nevada Vibration Sensor Working Principle

The keyphasor signal is a once per turn voltage pulse provided by a transducer normally an eddy current proximity measurement.

Bently nevada vibration sensor working principle.

So voltage difference of 2 to 10 and 10 to 18 is 8 volt. Proximity transducer system provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. Helooo friends in this video we explain why keyphasor installed in turbine its importance how it work. V to this day.

Hence it has remained 2. 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. It was quite literally based on which components were the least expensive when the technology was originally introduced 5. Vibration sensor working principle pdf viewer.

Bently nevada is an asset protection and condition monitoring hardware software and service company for industrial plant wide operations that has gained recognition as a leader in the field. Gap voltage of bently nevada vibration probe is usually set at 10v. This was not a deliberate effort to be different or non conformist on the part of bently nevada. Proximity transducers use eddy current principle to measure the distance between the probe tip and the surface to be observed.

The sensor itself is an encapsulated coil of wire energized with high frequency alternating current ac. To check the characteristics and healthiness of vibration probes make. Bently nevada vibration probes functional testing. 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.

The magnetic field produced by the coil induces eddy currents in the metal shaft of the. 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. 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.
