The 3300/16-14-01-03-00-00-00 is a dual-channel radial vibration and shaft gap monitor for the Bently Nevada 3300 rack system. It continuously monitors radial shaft vibration and average gap voltage, providing early detection of mechanical issues such as unbalance, misalignment, or bearing clearance changes.
This configuration is optimized for legacy 7200 series Proximitor sensors, with a sensitivity of 200 mV/mil and a measurement range of 0–10 mils peak-to-peak. Epoxy-sealed alarm relays ensure robust operation in harsh industrial environments.

Legacy Turbine Supervisory Instrumentation (TSI) in power plants, pumping stations, and refineries
Monitoring centrifugal compressors and large fans
Bridging older 7200 series sensors with modern 4–20 mA control systems
Ideal for harsh environments or non-climate-controlled rack installations
Why is 200 mV/mil sensitivity important?
Ensures accurate 0–10 mils monitoring when using legacy 7200 series Proximitor sensors. Using sensors with different scale factors requires verification of gap voltage and linearity to maintain measurement accuracy.
What does the epoxy-sealed relay option provide?
Protects the relays from moisture and atmospheric contaminants, increasing reliability in harsh or industrial settings.
