Configured for displacement measurement in 3300 XL monitoring systems, the Bently Nevada 330195-02-12-05-00 (330195 Proximity Probe) provides direct physical/electrical execution for non-contact shaft vibration and position monitoring.

Model Suffix Breakdown

The 330195 transducer is an 8 mm probe designed for specialized mounting configurations. Part number suffix details include:

• 02: Connector option (Miniature coaxial ClickLoc).

• 12: Total cable length (1.2 meters).

• 05: Agency approval (Multiple approvals).

• 00: Mounting thread option (Standard).

Hardware Specifications

Mechanical Monitoring & TSI Technical Attributes

The 330195 transducer utilizes eddy-current probe scaling to translate shaft displacement into a proportional voltage output. System accuracy relies on precise gap voltage validation, with a -10 VDC target often utilized for optimal linear range utilization. Integration into 3300 XL platforms requires careful consideration of rotor dynamics and mechanical tolerances. Field installation must prioritize cross-talk suppression by ensuring adequate separation between probes, preventing electromagnetic interference within the monitor array.

• 1 x Mounting nut set

• 1 x Connector boot protective kit

Field Installation Guidelines

• Mechanical Torque:

  Mounting nuts must be secured to a maximum of 13.5 N·m (120 in-lb). Exceeding this torque may damage the probe body threads.

• Cable Routing:

  Cables must be routed through grounded metal conduits to prevent signal attenuation and capacitive coupling from external noise sources.

• Connector Seating:

  ClickLoc connectors require manual seating until an audible click is detected. Do not utilize tools to force the connection.

• Thermal Integrity:

  Ensure the probe tip is installed within the operating temperature range to prevent insulation failure or drift in output sensitivity.

Frequently Asked Questions

• Can I use this probe with a non-XL Proximitor?

  No. The 330195 is designed for the 3300 XL system, and impedance mismatching with older Proximitor sensors will lead to calibration errors.

• What target material is required for this probe?

  Standard calibration is optimized for AISI 4140 steel. Variations in target metal composition require site-specific adjustments to the scale factor.

• How do I verify if the probe is functioning correctly?

  Verify the DC gap voltage at the monitor output while the machine is at a known steady-state distance from the probe tip.

• Is the connector waterproof?

  The connector interface is designed for industrial environments but is not rated for direct fluid immersion. Protective boots must be installed correctly.

• Does this probe support hazardous area operation?

  The -05 suffix indicates the unit holds relevant agency approvals for hazardous locations. Confirm regional certifications before installation.

• Can I splice the coaxial cable to increase its length?

  No. Any modification to the factory-set cable length changes the electrical characteristics and invalidates system accuracy.

• What happens if the probe tip is damaged?

  Mechanical damage to the probe tip distorts the RF field, leading to unreliable vibration readings and potential false monitor alarms.

• Is the probe hot-swappable?

  While the probe can be removed during machine operation, the monitor channel must be bypassed to prevent accidental machine trips during disconnection.
