330101-00-18-10-02-05 | Bently Nevada | Proximity Transducer

Configured for displacement measurement in rotating machinery, the Bently Nevada 330101-00-18-10-02-05 (330101-00-18-10-02-05 Proximity Transducer) provides direct physical signal transduction for proximity monitoring.

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The 330101-00-18-10-02-05 utilizes an eddy-current principle to detect shaft displacement, requiring precise calibration to a scaling factor of 7.87 V/mm. During installation, the gap voltage must be validated against the -10 VDC target, which represents the linear operating range midpoint. Accuracy in rotor dynamics observation, such as shaft centerline movement and vibration amplitude, is contingent upon maintaining this electrical gap. Signal integrity is sustained through standardized coaxial cabling, which minimizes cross-talk suppression interference within multi-channel machinery protection systems.

Frequently Asked Questions

Q: What is the required gap voltage for proper operation?

A: The probe must be adjusted to a gap voltage of -10 VDC at the monitor output. This ensures the transducer operates within its linear measurement range.

Q: Are these transducers interchangeable with other probe types?

A: No. The 330101 series is matched to specific Proximitor sensor electronics. Mixing different probe/cable/sensor combinations will introduce non-linearities and measurement errors.

Field Installation Guidelines

• Mounting: Ensure the probe is mounted in a non-conductive or properly isolated bracket. Verify that the probe tip is perpendicular to the target surface.
• Grounding: The probe case must be grounded to the machine casing to minimize electromagnetic interference. Ensure that no stray currents flow through the probe housing.
• Thread Engagement: For NPT threads, ensure a minimum of 5 full thread engagements to maintain structural stability under vibration.
• Cable Routing: Route coaxial cables through dedicated conduit, separated from high-voltage AC lines to prevent induced noise on the displacement signal.
