Description Reviews

The Bently Nevada 330801-28-04-050-00-02, also cataloged as the 330801 Proximity Transducer Assembly, operates as a dedicated hardware component for non-contact vibration and axial position measurement within 3300 XL series monitoring networks. The assembly yields non-contact target position signals via an integrated 3300 XL 8 mm eddy-current probe element.

Mechanical Monitoring and TSI Integration

The 3300 XL proximity transducer assembly utilizes high-frequency electromagnetic induction to measure distance changes between the 8 mm probe tip and the target shaft surface. Accurate rotor dynamics tracking requires strict alignment with the 8.0 V/mm nominal sensitivity to guarantee proportional scaling across the entire 2 mm linear range.

During field configuration, gap voltage validation (-10 VDC targets) confirms proper mechanical positioning within the linear operating band before locking the assembly. Multi-transducer configurations maintain high cross-talk suppression by enforcing spacing limits between adjacent probe tips to eliminate mutual high-frequency carrier signal distortion.

Frequently Asked Questions

Q: What mounting thread connection is provided on the 330801-28-04-050-00-02 assembly?

A: The housing features a standard 3/4-14 NPT external thread for rigid direct mounting into machine housing ports or standoff adapters.

Q: Is this proximity transducer assembly rated for outdoor or submerged field locations?

A: Yes. The stainless steel casing and integrated cable housing carry an IP68 ingress protection rating suitable for continuous outdoor or wet operating conditions.

Q: What power input is required for the transducer signal conditioning loop?

A: The loop operates on an external 24 VDC power supply to provide signal excitation and output conditioning.

Field Installation Guidelines

Thread the 3/4-14 NPT stainless steel assembly into the machine mounting port, ensuring clean NPT thread engagement (typically 5 turns hand-tight plus wrench tightening) without over-torquing.
Set physical gap distance and complete gap voltage validation (-10 VDC targets) using a digital multimeter across field terminal test points prior to finalizing mounting locks.
Inspect all cable entry interfaces and seal NPT threaded joints to preserve the IP68 environmental protection rating against moisture ingress.
Route the 50 ft cable lead through grounded protective conduit, segregating signal lines from high-voltage motor supply wiring.
Terminate signal cable shielding at the main monitor chassis ground point only, keeping the probe body isolated to prevent ground loops.
