Features:

  • Integrated probe and Proximitor sensor architecture reduces external wiring and eliminates the need for a separate extension cable.
  • UV-resistant glass reinforced PPS housing provides improved durability and electrostatic charge dissipation in severe industrial environments.
  • IP66 and Type 4X enclosure protection supports reliable operation in applications exposed to moisture, dust, and contaminants.
Bently Nevada 330880-28-15-044-01-02 is designed for industrial rotating machinery monitoring where dependable proximity measurement is essential for equipment protection. The assembly combines probe and signal conditioning components into one compact housing to simplify field installation. Direct monitor wiring further reduces system complexity in plant environments. The rugged enclosure design also helps improve long-term reliability in demanding operating conditions.

The PROXPAC XL assembly uses a 3300 XL 8 mm probe with Multiple Approvals together with a 1.5 in standoff adapter and 4.4 in penetration dimension. By integrating the Proximitor sensor inside the housing cover, the system avoids the need for a separate external enclosure. This arrangement can reduce installation time and simplify maintenance access for technicians working around turbines, compressors, and pumps. The assembly also retains the accessibility advantages associated with earlier 31000 and 32000 housing styles.

Bently Nevada 330880-28-15-044-01-02 uses a polyphenylene sulfide thermoplastic housing reinforced with glass and conductive fibers for additional mechanical strength and electrostatic dissipation capability. The enclosure is verified to IP66 protection according to BASEEFA report number T07/0709 and also supports Type 4X environmental performance. These characteristics make the assembly suitable for industrial sites where vibration monitoring equipment may be exposed to moisture, dust, or corrosive conditions. The durable construction supports continuous monitoring applications across a wide range of industrial processes.

The 330880-28-15-044-01-02 Bently Nevada PROXPAC XL Proximity Transducer Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • High Protection Rating: Utilizing a robust PROXPAC XL housing, the internal preamplifier (Proximitor) is physically protected against dust and water, making it suitable for harsh industrial open-air environments.
  • Resistant to Corrosive Media: The housing and seals are specially treated to effectively resist corrosive gases, chemical acids and alkalis, and oil contamination commonly found in oil refineries and chemical plants.
  • Stable Operation Over a Wide Temperature Range: The system and probe components maintain high-precision output under extreme industrial high and low temperature cycles, preventing measurement drift caused by drastic temperature fluctuations.
  • Superior Shock Resistance: The overall structure is specifically designed for installation near rotating machinery bearing housings or high-vibration enclosures, providing excellent mechanical shock and impact resistance.
  • Firmware-Free Hardware Design: This component serves as a physical protection integrated housing for the eddy current sensor and preamplifier. Internally, it involves pure analog hardware calibration and does not involve software firmware upgrades.
  • Electrical Characteristic Pre-calibration: The internally integrated 3300 XL preamplifier has its physical parameters pre-fixed at the factory, achieving precise linear output without requiring on-site programming by the user.
  • Linearity Hardware Compensation: Built-in circuitry automatically compensates for the capacitance and inductance of the probe and extension cable through pure hardware logic, ensuring signal consistency when matched with cables of different lengths.
  • System Maintenance-Free Operation: Due to the absence of firmware crashes or data loss, the card and housing components maintain highly robust plug-and-play characteristics throughout their entire lifecycle.
  • Steam Turbine Shaft Vibration Monitoring: Installed on the bearing housing of steam turbines in large power plants, the integrated housing protects the probe connector and monitors the radial vibration of the shaft in real time.
  • Compressor Axial Displacement Measurement: Used in high-pressure centrifugal compressors in the petrochemical industry, accurately measuring the axial movement of the rotor in hazardous outdoor environments to prevent bearing wear.
  • Early Fault Warning for Industrial Fans: Widely used in large induced draft fans and exhaust fans in metallurgical and cement plants, protecting the sensor from physical abrasion from high concentrations of dust and particulate matter.
  • Critical Pump Unit Asset Status Monitoring: In the harsh operating areas of high-pressure feedwater pumps or crude oil transfer pumps, as part of intrinsically safe or explosion-proof protection, centralized feedback of mechanical health status is conducted.
Description
Bently Nevada 330880-28-15-044-01-02 delivers a compact and fully integrated proximity probe solution for rotating machinery monitoring applications. Unlike conventional arrangements that require separate probe housings and extension cables, the PROXPAC XL assembly incorporates the 3300 XL Proximitor sensor directly inside the housing cover. This configuration simplifies installation and reduces external connection requirements between the probe and monitoring equipment.

The assembly uses a 3300 XL 8 mm probe with Multiple Approvals and includes a 1.5 in (38 mm) standoff adapter together with a 4.4 in probe penetration dimension. Field installation flexibility is improved through one 3/4-14 NPT fitting with two plugs and a required 3/4-14 NPT mounting thread option. Direct wiring between plant monitors and the PROXPAC XL assembly eliminates the need for an additional Proximitor housing, helping reduce cabinet space and wiring complexity in industrial systems.

Bently Nevada 330880-28-15-044-01-02 is built for harsh operating environments where vibration monitoring equipment is exposed to moisture, contaminants, and mechanical stress. The housing construction uses ultraviolet-resistant glass reinforced polyphenylene sulfide (PPS) thermoplastic containing conductive fibers. Compared with earlier steel and aluminum housing designs, the PPS material improves corrosion resistance while helping dissipate electrostatic charges more effectively.

The PROXPAC XL enclosure provides Type 4X and IP66 environmental protection, with the IP66 rating verified by BASEEFA report number T07/0709. The rugged housing design shares the same external adjustment and accessibility advantages found in previous 31000 and 32000 proximity probe housing assemblies while introducing a more compact self-contained architecture. Bently Nevada 330880-28-15-044-01-02 is well suited for turbines, compressors, pumps, and other critical rotating equipment where dependable proximity measurement and simplified maintenance are important.
