Description：

The primary uses for the 3300 XL NSv Transducer System arefor areas where counter bore, sideview, or rearviewrestrictions limit the use of standard Bently Nevada 3300 and3300 XL 5 and 8 mm Transducer Systems. It is also ideal forsmall target applications, such as measuring radial vibrationon shafts smaller than 51 mm (2 in) or axial position on flattargets smaller than 15 mm (0.6 in). It is primarily used in thefollowing applications on fluid-filmed bearing machineswhere a small shaft or reduced side-view is present:

Radial vibration and radial position measurements

Axial (thrust) position measurements

Tachometer and zero speed measurements

Phase reference (Keyphasor signals)

Product Applications

Electric power industry (thermal power, wind power generation): Used for monitoring the vibration and rotational speed of the bearings of small steam turbines, hydroelectric generators, and power generation units.

Petrochemical industry: In centrifugal compressors, pumps, and expanders, monitor the amplitude of high-speed rotating shafts to prevent friction between the shaft and the bearings.

Steel metallurgy: For key rotating parts of large fans, blowers, and rolling mill systems, capture micrometer-level displacement changes in real time.

Main functions and purposes:

Vibration measurement: Real-time sensing of the radial vibration of the shaft. When the vibration exceeds the limit, it triggers an alarm or initiates an interlock shutdown.

Displacement monitoring: Measuring the relative position changes of the shaft within the bearing (such as axial movement).

Speed/phase detection: Can be used as a phase sensor to provide an accurate reference signal for rotational speed.
