PROXPAC XL Proximity Transducer | 330881-BR-05-060-00-02 | Bently Nevada

Technical Specifications

The Bently Nevada 330881-BR-05-060-00-02 is a PROXPAC XL Proximity Transducer used for online monitoring and protection of shaft vibration, shaft displacement, key phase, and eccentricity in industrial rotating machinery such as steam turbines, compressors, pumps, and generators.

Original Outlet Thread Specifications: The PROXPAC XL's polyphenylene sulfide (PPS) housing, without any external connectors, has three original electrical outlet holes with 1/2-14 NPT American standard tapered pipe threads.

Multi-hole Full Seal Guarantee: At the factory, two of the three 1/2-14 NPT holes are sealed with original factory explosion-proof plugs. During installation, only the remaining hole needs to be used to introduce a three-core shielded cable. If a "one in, one out" series connection or a separate grounding wire is required on-site, one of the plugs can be manually removed.

50 mm Base Mechanical Rigidity and Advantages

Perfect Cantilever Safety Ratio: The sleeve extends 60 mm inwards, with an external shim of 50 mm. This near 1:1 structure ensures extremely uniform lateral shear stress distribution for the sensor when facing high-speed oil mist erosion inside the machine or mechanical vibration from a high-power motor.

Reverse locking torque: After precise alignment of the gap voltage, a reverse locking nut is required to secure the 3/4-14 NPT mounting thread. The 50 mm height provides ample clearance for a standard open-end wrench or hydraulic torque wrench.

Technical FAQ

Q: If a leak in the production line's process piping causes a high concentration of hydrogen sulfide gas to adhere to the surface of the 330881-BR-05-060-00-02 cable, will it corrode?
A: The polyphenylene sulfide (PPS) used in its outer shell and the internal probe material have extremely strong chemical resistance to hydrogen sulfide (H2S).

Q: Compared to the previous "-06" armored cable model, what are the cost advantages of the "-00" option for the 330881-BR-05-060-00-02?
A: The "-00" option does not include the previously expensive stainless steel armored components, allowing users to choose more economical cable connectors based on site wiring specifications.

Q: How do I determine the linear range center when calibrating the 330881-BR-05-060-00-02 in the field?
A: Adjust the magnetic field gap until the DC output voltage of the integrated component stabilizes at approximately -10.0 Vdc; this will achieve the linear range center.

Q: How are the electronic components inside the preamplifier of model 330881-BR-05-060-00-02 protected from damage by the gas turbine casing, which is subjected to severe vibrations?
A: The circuit board on top of the casing uses an integral epoxy resin curing and potting process, which provides excellent impact resistance and mechanical vibration resistance.
