Technical Questions & Answers
Q1: What does the 330100-50-02 mainly monitor?
It’s a 3300 Proximitor Sensor used in fluid film bearing systems, mainly for turbines and compressors. It picks up shaft displacement, eccentricity, and radial vibration in real time. The signal basically reflects how the shaft moves inside the bearing clearance, especially in steam turbines, gas turbines, and centrifugal compressors where stability is critical.
Q2: Why is the 5m cable of the 330100-50-02 important?
The “-50” version is tuned for a 5-meter system length. That’s why the probe and extension cable need to stay as-is. Any change can affect impedance and the 200 mV/mil scale factor, so most technicians just keep the factory cable setup.
Q3: How does the 330100-50-02 work in ESD or hazardous systems?
In ATEX/CSA areas, it runs as part of an API 670 protection system on -24 VDC supply. The analog signal goes into the rack, and if vibration or thrust goes beyond limits, it can feed into an Emergency Shutdown System (ESD) through the monitoring logic.
Q4: Can the 330100-50-02 integrate with 3500 systems and legacy setups?
Yes. It connects directly to Bently Nevada 3500 modules like 3500/40M or 3500/42M. With 3500/01 configuration software, it can be mapped for legacy 3300 systems and then processed through TDI into System 1 for diagnostics.
