PROXPAC XL Proximity Transducer | 330881-BR-04-110-06-02 | Bently Nevada

Technical Specifications

The Bently Nevada 330881-BR-04-110-06-02 is a PROXPAC XL Proximity Transducer, part of Bently Nevada's asset protection and condition monitoring product line. It is used for monitoring shaft vibration, shaft displacement, and key phase speed in industrial rotating machinery.

Eliminates Extension Cables: This component directly encapsulates the 3300 XL 8mm probe and Proximitor preamplifier within a single housing. Expensive extension cables are no longer needed in the field, nor is a separate preamplifier junction box required near the unit. Outgoing cables can be directly connected back to the 3500 monitoring system frame.

Physical Dimension Verification: When replacing or installing in the field, always verify that the insertion depth of the old component is precisely 110 mm. Incorrect insertion depth may cause the probe to strike the rotating shaft due to excessive length, or exceed the effective linear measurement range of the 3300 XL 8mm probe due to insufficient length.

Unique 110 mm Probe Sleeve Design

Reinforced Sleeve Protection: The 330881 metric stainless steel sleeve is specifically calculated for lateral stiffness. The 110 mm long sleeve is designed to withstand lateral impact vibrations of up to 20 g, ensuring that the probe tip does not experience minor lateral swaying under oil flow impact. 

Physical rigidity constraint: When installing to this 110 mm depth, ensure that the clearance between the inner diameter of the machine mounting hole and the outer diameter of the 330881 casing meets Bentley's original specifications and is not too wide, so that the machine casting can provide some physical support for the long casing in the event of oil flow impact.

Technical FAQ

Q: What external circuit power supply voltage is required for the 330881-BR-04-110-06-02 when connected to a monitoring system?
A: Without an isolation barrier, its standard loop operating power supply voltage is -17.5 Vdc to -26 Vdc.
