Configured for non-contacting shaft displacement tracking in 3300 XL Machinery Protection System networks, the Bently Nevada 330104-00-13-05-02-00 (330104 Proximity Probe) provides direct physical/electrical execution. The component establishes a localized eddy-current field against rotating or reciprocating machinery shafts, converting physical gap deviations into high-frequency impedance changes that are transmitted via a miniature coaxial cable to an external Proximitor sensor interface.

Gap Voltage Validation (-10 VDC Targets)

Field calibration requires strict gap voltage validation to anchor the probe within its linear measuring range. During installation, the mechanical depth of the 130 mm stainless steel case must be physically adjusted within the mounting bore while reading the DC bias voltage output from the corresponding Proximitor circuit. Technicians must position the probe tip to secure a static gap voltage validation target of exactly -10 VDC, which positions the target face at the exact center of the linear calibration slope. This precise mechanical positioning ensures linear output for dynamic rotor dynamics monitoring and maximizes cross-talk suppression between close-proximity sensor pairs.

Frequently Asked Questions

Q: Can this 0.5-meter total length probe connect directly to a standard 5.0-meter Proximitor sensor?

A: No. The proximity transducer loop requires a matched total electrical length. A 0.5-meter total length probe must be paired exclusively with a 4.5-meter extension cable to satisfy the total 5.0-meter electrical system length parameter of the Proximitor.

Q: What is the mechanical function of the integrated ClickLoc coaxial connector?

A: The option 02 ClickLoc connector acts as a positive-locking coaxial interface that resists detachment from vibration. It is a dry connection and must be kept clean and free of lubricants or moisture to prevent signal degradation.

Field Installation Guidelines

  • Mounting Torque Restrictions: When installing the 130 mm metric threaded probe housing into the machine housing port, limit mechanical torque to a maximum of 33.9 N-m (300 in-lb) to prevent thread binding or casing structural deformation.
  • Coaxial Lead Bend Radius: Route the 0.5-meter standard cable assembly with a minimum bend radius of 25.4 mm (1.0 inch) to protect the internal coaxial shielding layers from mechanical fatigue.
  • Connector Ground Isolation: Ensure that the outer conductor shell of the ClickLoc connector joint is insulated from the machine casing. All signal shields must terminate at the common terminal ground of the monitoring enclosure to prevent ground loops.
