3300 XL 8 mm Proximity Probe | 330102-00-20-30-12-CN | Bently Nevada

Technical Specifications

The 3300 XL 8 mm Proximity Transducer System provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements. 

Key Points for Installation and Routine Maintenance

Gap Setting: With the machine stationary, the official recommendation is to adjust the initial gap to approximately -9.0 VDC (linear center point, corresponding to approximately 1.27 mm or 50 mils gap) by measuring the DC voltage.

Cable Bending Radius: Although protected by stainless steel armor, the bending radius of the armored cable should not be less than 25.4 mm (1 inch). Excessive bending can damage the internal coaxial cable or change its impedance, thus affecting measurement accuracy.

Troubleshooting Related Issues

Open Circuit (Cable Breakage or Loose Connector): The OUT voltage of the preamplifier output will typically drift to the power rail limit of approximately -23 VDC to -26 VDC.

Short Circuit (Probe Directly Pressing Against the Metal Shaft): The OUT voltage of the preamplifier output will approach 0 VDC to -1 VDC.
