Bently Nevada 330881-16-00-060-01-02 PROXPAC XL Proximity Transducer

Description

330881-16-00-060-01-02 specifies a metric PROXPAC XL Proximity Transducer configuration engineered with a 3300 XL 8 mm probe without hazardous area approvals (Option 16). This specific transducer assembly eliminates the standoff adapter (Option 00) and is optimized with a 60 mm probe penetration sleeve (Option 060), a metric Fittings kit containing one M25 fitting and two plugs (Option 01), and a 3/4-14 NPT mounting thread (Option 02). By integrating both the proximity probe and the Proximitor sensor into a single, advanced Polyphenylene Sulfide (PPS) housing, this self-contained design simplifies field installations and eliminates the need for separate extension cables and dedicated Proximitor enclosures.

Unlike hazardous-area configurations utilizing Option 28 (which includes multiple safety certifications), this Option 16 model is designed specifically for general-purpose, non-hazardous industrial environments, offering a cost-effective solution for safe-area machinery monitoring. The 60 mm penetration sleeve length provides a compact casing reach ideal for shallow-to-medium machinery housing depth configurations, while the M25 metric fittings and 3/4-14 NPT thread allow rigid, environmentally sealed connections directly to the machine casing and standard conduit networks.

Features

• Integrated Enclosure Design: Houses both the 3300 XL 8 mm probe and the Proximitor sensor inside a single cover, removing intermediate cabling and reducing field wiring connections.
• Option 16 Probe System: Incorporates a standard-performance 3300 XL 8 mm proximity probe configured for safe, non-hazardous areas.
• 60 mm Metric Penetration (Option 060): Medium sleeve penetration length allows precise gapping and protective isolation of the probe case.
• No Standoff Adapter (Option 00): Configured for direct casing mount without standoff clearance requirements.
• One M25 Fitting Kit (Option 01): Includes one metric M25 cable conduit fitting and two blanking plugs for reliable environmental sealing.
• Rugged PPS Housing: Glass-reinforced, conductive-fiber-filled Polyphenylene Sulfide thermoplastic enclosure provides excellent structural integrity, dissipates electrostatic charges, and resists corrosive environments.
• IP66 and Type 4X Rating: Certified to seal effectively against ingress from dust and high-pressure hose-directed water.

Applications

Typical applications include radial shaft vibration, axial position, and speed measurements on rotating machinery situated in non-hazardous plant sections. This transducer is widely used on industrial pumps, fans, compressors, small steam turbines, and blowers where physical space constraints prevent the installation of separate, external Proximitor housing boxes.

Installation Guidelines

• Gap Setting Check: Verify the target gap is set to approximately 1.27 mm (50 mils), corresponding to an output voltage of -10.0 Vdc, to align measurements in the center of the linear calibration band.
• Sleeve Support Rule: If the total length of the sleeve exceeds 305 mm (12 in), additional physical supports or clamping should be used close to the probe head to prevent mechanical resonance and ensure probe stability.
• Moisture Ingress Prevention: Ensure that all cover gaskets, plug threads, and conduit entries are fully sealed. Users must take adequate steps to prevent condensation from traveling down conduit lines into the housing terminal area.
• Wiring Specifications: Utilize 0.2 to 1.5 mm2 (16 to 24 AWG) 3-conductor shielded triaxial cable. Keep the run distance below 305 m (1000 ft) to preserve full dynamic frequency response.

Compliance and Certifications

• CE Mark: Compliant with European EMC Directive 2014/30/EU
• RoHS: Compliant with Directive 2011/65/EU
• Enclosure Verification: IP66 verified by BASEEFA under report T07/0709
• Hazardous Area Rating: This Option 16 configuration does not carry hazardous-area certification. Designed for safe areas only.
