Bently Nevada 330104-00-08-90-02-05 Proximity Probe

Bently Nevada 330104-00-08-90-02-05 Proximity Probe Configured for machinery protection and condition monitoring in turbomachinery systems, the Bently Nevada 330104-00-08-90-02-05 (330104 proximity probe) provides direct non-contact eddy current transducer execution. Part Number Breakdown Model (330104): 3300 XL 8 mm proximity probe Unthreaded Length (00): 0 mm unthreaded portion Overall Case Length (08): 80 mm (8 cm) case length Total Length (90): 9.0-meter (29.5-feet) total cable length Connector/Cable (02): Miniature coaxial ClickLoc connector with standard cable Agency Approval (05): CSA, ATEX, and IECEx hazardous area approvals Hardware Specifications Parameter Specification Model 330104-00-08-90-02-05 Brand Bently Nevada Origin USA Weight Not specified Dimensions Tip diameter 8 mm; case length 80 mm; total cable length 9.0 m Operating Temp Not specified Power Consumption Passive probe, excitation via proximitor Core Performance Non-contact eddy current transducer; Viton O-ring sealing; miniature coaxial ClickLoc connector Eddy-Current Probe Scaling and Gap Voltage Validation The probe operates with calibrated eddy-current scaling to ensure accurate rotor dynamic measurements. Gap voltage validation targets -10 VDC reference points, enabling precise monitoring of shaft displacement. Signal cross-talk suppression is integrated through coaxial shielding, minimizing interference across multiple probe channels. Frequently Asked Questions Q: Does the 330104 probe support hot-swap installation? A: No. The probe requires full system shutdown before removal or replacement to maintain calibration integrity. Q: What is the typical backplane current load when connected to a proximitor? A: The probe itself is passive; current load is determined by the proximitor driver, not the probe. Q: Is firmware compatibility relevant for this probe? A: No. The probe is a passive transducer and does not contain firmware. Compatibility is defined by proximitor module configuration. Field Installation Guidelines Ensure probe tip is inserted with full thread engagement to maintain mechanical stability. Ground coaxial shielding at the proximitor end to suppress cross-talk and noise. Route cables away from high-voltage lines to avoid induced interference. Maintain sealing integrity by verifying Viton O-ring compression between probe tip and case. Confirm hazardous area approvals (CSA, ATEX, IECEx) before installation in classified zones.
