Bently Nevada 330162-02-85-85-80-80-94-01-02 Feedthrough

Bently Nevada 330162-02-85-85-80-80-94-01-02 3300 Series Dual Triaxial HP Feedthrough

Product Overview

The Bently Nevada 330162-02-85-85-80-80-94-01-02 is a dual triaxial high-pressure feedthrough. It provides a pressure-tight seal up to 2.76 MPa (400 psi) for machinery casings. Engineers use this unit to route proximity probe cables safely from internal pressurized zones to external monitoring systems. The feedthrough maintains system electrical length and signal integrity across pressurized barriers. It features robust armor protection and chemical-resistant Fluorocarbon O-rings for demanding industrial environments.

This model routes two independent cables simultaneously while preserving signal purity. It connects internal proximity transducers to external 3300 Series Proximitor sensors without impedance mismatch. Plant operators rely on this component to eliminate gas or liquid leakage along sensor wiring routes.

Global PLC Spare HUB's Insight

In high-pressure turbomachinery, seal integrity at cable exit points remains critical. The Bently Nevada 330162-02-85-85-80-80-94-01-02 solves gas leakage risks in pressurized casings. Standard cable glands often degrade under dynamic pressure cycling or hydrocarbon exposure. The 3300 Series HP feedthrough utilizes precision-machined Fluorocarbon seals to ensure zero-leakage performance. It preserves exact electrical length specs for precise shaft vibration monitoring. Field engineers appreciate the ClickLoc connectors, which prevent accidental loosening due to machine vibration.

• Subsea pumps and offshore gas extraction skids
• Hydrocarbon expanders and refrigeration units
• Boiler feed pumps operating under high ambient casing pressures

Installation Guide

• Verify casing thread dimensions and clean the mounting port thoroughly before threading.
• Inspect the Fluorocarbon O-ring for surface defects or contamination prior to insertion.
• Apply suitable thread sealant to NPT body threads according to plant safety specs.
• Pass internal probe leads through the high-pressure side using hand-tightened ClickLoc connections.
• Torque the feedthrough body into the machine casing to specified engineering limits.
• Connect male low-pressure connectors to external extension cables or 3300 XL Proximitor units.
• Conduct pressure leak testing before bringing the machine casing up to operating pressure.

Maintenance & Diagnostic Accessibility

The Bently Nevada 330162 feedthrough features ClickLoc gold-plated connectors. Technicians join connectors using finger-tight torque without needing special calibration tools. The male and female connector arrangement prevents improper cable cross-wiring during turnarounds. Built-in triaxial shielding isolates vibration signals from plant electrical noise. Field teams can measure loop resistance directly at the external connection port during routine maintenance.

Frequently Asked Questions (FAQ)

Q: What does option code 94 signify for O-ring selection?

A: Option 94 specifies Fluorocarbon material. This material resists exposure to natural gas, butane, fuel oil, and synthetic turbine lubricants.

Q: How does this feedthrough maintain vibration signal accuracy?

A: It replaces standard extension cable sections while matching exact capacitance and inductance parameters. This design keeps total system electrical length perfectly balanced.

Q: Can I use this feedthrough with non-Bently Nevada proximity probes?

A: No. It matches specific impedance curves for 3300 XL 8 mm, 3300 XL 11 mm, and 3300 5 mm probe systems.

Q: How do ClickLoc connectors benefit field technicians during installation?

A: ClickLoc connectors require only finger torque to lock securely. They prevent connection loosening under severe machine vibration without overtightening risks.

Q: How do I select correct cable lengths (Dimensions 1 through 4)?

A: Measure internal casing distance and external routing length. Match the combined probe, feedthrough, and extension cable length to your Proximitor system requirement (5m or 9m total length).
