Description

The Bently Nevada 330881-28-00-050-03-02 PROXPAC XL Proximity Transducer, Metric is a completely self-contained proximity probe system for machinery condition monitoring applications. 330881 integrates the proximity probe, housing, and 3300XL Proximitor sensor into a single assembly, eliminating the need for an extension cable between the probe and its associated Proximitor sensor. This integrated design of 330881 also eliminates the need for a separate Proximitor housing, as the field wiring connects directly between the monitors and the PROXPAC XL assembly.

330881 is constructed from Polyphenylene Sulfide (PPS), an advanced molded thermoplastic material that replaces the steel and aluminum used in previous Bently Nevada housing designs. The PPS material of 330881 incorporates glass fibers for structural strength and conductive fibers for effective electrostatic charge dissipation. This advanced material construction of 330881 provides superior resistance to chemical attack, UV degradation, and environmental stress compared to traditional metal housings. The housing of 330881 is rated for Type 4X and IP66 environments, providing extra protection in severe industrial conditions including exposure to dust, water jets, and corrosive atmospheres.

The Bently Nevada 330881-28-00-050-03-02 PROXPAC XL Proximity Transducer is a fully integrated proximity transducer assembly for continuous shaft vibration and position monitoring in rotating machinery. The 330881-28-00-050-03-02 combines a 3300 XL 8 mm proximity probe, an integrated 3300 XL Proximitor Sensor, and the required mounting hardware into a single compact assembly, eliminating the need for a separate extension cable between the probe and Proximitor sensor.

The Bently Nevada 330881-28-00-050-03-02 is configured with a 50 mm probe penetration, one M20 fitting, two sealing plugs, and a 3/4-14 NPT mounting thread. The assembly includes a 3300 XL 8 mm probe with Multiple Approvals, making it suitable for installations that require certified hazardous-area compliance. The integrated design simplifies installation while reducing wiring complexity inside machinery monitoring systems.

The 330881-28-00-050-03-02 Bently Nevada PROXPAC XL Proximity Transducer,Metric may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
The housing is constructed from Polyphenylene Sulfide (PPS), an advanced UV-resistant, glass-reinforced thermoplastic material incorporating conductive fibers. This replaces the steel and aluminum used in previous 31000/32000 housing designs, providing enhanced electrostatic charge dissipation while maintaining structural integrity. The housing carries an IP66 and NEMA Type 4X rating, verified by BASEFFA report T07/0709, for protection against dust ingress and high-pressure water jets.
 
The integrated Proximitor sensor eliminates the need for a separate extension cable between the probe and the signal conditioning electronics, and removes the requirement for an external Proximitor housing. Field wiring connects directly between the monitoring system and the PROXPAC XL assembly. The unit accepts a 3300 XL 8 mm proximity probe with a 1-metre cable length installed in the probe sleeve, featuring a PPS probe tip and AISI 304 stainless steel probe case.
  • Oil/Gas/Petrochemical: Monitors critical machinery processing volatile hydrocarbons in hazardous explosive zones
  • Power Generation: Tracks turbine/generator shaft movements in thermal, nuclear, and hydro plants
  • Chemical Processing: Resists corrosive vapors with PPS thermoplastic housing
  • Water/Wastewater: Operates reliably in moisture/humidity/outdoor spaces with IP66 washdown protection
  • Mining/Heavy: Withstands dust, abrasive particles, and extreme mechanical vibration
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Thread Engagement: Ensure the target measurement surface is within the probe's linear range. Thread the assembly into the machine case or bracket.
Penetration Depth: The probe tip must penetrate exactly 50 mm into the housing/measurement zone according to your part number.
Locking & Torque: Once properly positioned, lock the assembly in place using the mounting threads.
Target Alignment: Verify the probe is centered over the target (typically AISI 4140 steel) and that the minimum target area is not violated.

Technical notes

330881 features a threaded sleeve that allows ±12.7 mm (0.5 in) adjustment from the mid-setting distance between the mounting surface and target surface. This adjustment capability of 330881 enables precise probe-to-target gap setting during installation and commissioning. The "B" plus "C" dimension of 330881 represents the mid-setting distance between the mounting surface and target surface, with the threaded sleeve providing the ±12.7 mm adjustment range. For "B" plus "C" dimensions greater than 305 mm (12.0 in), additional sleeve support near the probe is required to stiffen the assembly and avoid the influence of resonance.
