The Bently Nevada 3300/20 Dual Thrust Position Monitor is a specialized, rack-mounted instrumentation module designed to provide early warning of thrust bearing failure by continuously measuring and tracking two independent channels of shaft axial position. Operating within a dedicated machine protection framework, the device hooks directly into external proximity sensor probes to evaluate raw electrical gap voltages reflecting structural collar movement.

² Number of Channels: 2 independent, fully configurable axial thrust measurement channels.

² Power Supply Voltage: Draws low-voltage DC power natively through its insertion slots in the Bently Nevada 3300 Power Supply Rack.

² Input Signal Source: Connects to Bently Nevada 7200 or 3300 proximity transducer probe systems.

² Operating Temperature Window: Hardened for plant-floor machine panels, running reliably from 0°C to 65°C (32°F to 150°F).

² Storage Temperature Tolerance: Resilient across facility warehouse climates from -40°C to 85°C.

Thrust Bearing Failure Early Warning:

Turbomachinery Axial Safety Protection:

False Trip Mitigation via Voting:

Continuously monitors the axial positioning of high-stakes shafts relative to inner clearances to provide immediate warning before thrust bearings undergo severe structural degradation.

Deployed as a safety trip controller on massive steam turbines, gas turbines, and high-performance process compressors.

Utilizes localized AND logic voting schemes across two distinct probes pointing at the same rotor collar to prevent unnecessary factory shutdowns during minor sensor failures.
