Bently Nevada 330880-16-35-036-00-02 PROXPAC XL Proximity Transducer

Description

The Bently Nevada 330880-16-35-036-00-02 is a self-contained proximity transducer system designed for continuous vibration and position monitoring in harsh industrial environments. This specialized PROXPAC XL proximity transducer assembly integrates the functionalities of a conventional proximity probe housing and a 3300 XL Proximitor sensor directly into the housing cover. This integrated approach eliminates the need for an external extension cable and separate sensor housing, allowing field wiring to connect directly from the monitoring system to the assembly. Encased in a glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic housing with conductive fibers, the system provides excellent resistance against mechanical impacts and dissipates electrostatic charges effectively. The system interfaces with a standard 3300 XL 8 mm proximity probe and provides a reliable analog voltage output directly proportional to the distance between the probe tip and the target surface. It is widely used in Machinery Protection Systems (such as Bently Nevada 3500 Series) for monitoring critical machinery parameters like radial vibration, axial position, and shaft alignment across demanding industries including oil and gas, power generation, and chemical processing.

Features

• Integrated Design: Combines standard proximity probe housing benefits with an on-board 3300 XL Proximitor sensor inside the cover, minimizing cable runs and external footprint.
• Advanced Material Construction: Molded Polyphenylene Sulfide (PPS) housing with glass and conductive fibers offers higher strength and replaces traditional steel/aluminum.
• Severe Environment Protection: Rated for Type 4X and IP66 environments to secure internal electronics from moisture, dust, and corrosive ambient elements.
• Electrostatic Dissipation: Conductive fibers blended into the thermoplastic housing body effectively dissipate accumulated electrostatic charges.
• Direct Field Wiring: Field connections connect directly between monitors and the PROXPAC XL assembly, removing additional intermediate terminations.
• External Sensor Adjustment: Retains full compatibility with structural advantages of 31000/32000 housings for simple external probe gap positioning.

Applications

• Steam and Gas Turbine Shaft Vibration and Thrust Position Monitoring

Installation Guidelines

• Sleeve Structural Support: If the combined total of Dimension "B" (Standoff Adapter) and Dimension "C" (Probe Penetration) exceeds 305 mm (12.0 in), you must add an extra sleeve support mechanism near the probe body to stiffen the overall assembly and prevent resonance issues under operational frequencies.
• Probe Gap Positioning: Ensure initial mechanical gapping is targeted at the center of the sensor's linear range—ideally 1.27 mm (50 mils) from the shaft target. The integrated threaded sleeve configuration allows manual position trimming of +/- 12.7 mm (0.5 in) from the baseline target setting.
• Conduit Routing & Moisture Control: Although the PPS enclosure seals tightly against external spray, users must deploy standard sealing dopes or physical isolation traps on conduit entry points to block environmental moisture from traveling down the conduit pipeline directly into the terminal block area.
• Cross-Talk Mitigation: Maintain a baseline structural spacing between nearby transducer tips of at least 40 mm (1.6 in) during axial configurations, or 38 mm (1.5 in) for radial vibration frameworks to keep electromagnetic cross-talk interference below 50 mV.
