Product Introduction
BENTLY 3300/65-03-01-00-00-00-01 is a dual probe monitor for fluid film bearing machines. It mathematically sums relative shaft vibration and casing vibration to provide absolute shaft data.
This industrial automation unit is essential for large steam and gas turbines where casing movement is significant. It provides four distinct measurements to ensure complete rotor dynamic analysis.

Quality Control Process
We validate every BENTLY 3300/65-03-01-00-00-00-01 before shipment. First, we inject simulated proximity and seismic signals to verify the internal vector summation math.
Next, we test the 0-15 mils full-scale range to ensure alarm relays trip at the exact programmed setpoints. We also verify the DC gap measurement accuracy against a calibrated reference voltage.
Finally, each replacement module ships in anti-static shielding with desiccant packs. This prevents moisture ingress during transit.
Replacement Pitfall Guide
❗ Obsolete Hardware Warning: The 3300 series was classified as obsolete in 2014. Support is strictly limited, and you should plan a migration to the 3500 series as soon as possible.
❗ Range Code Verification: The “03” in your part number dictates a 0-15 mils range. Installing a 0-10 mils or 0-20 mils module will cause severe scaling errors in your DCS.
❗ Casing Vibration Transmission: Do not use this module unless your machine actually transmits significant vibration to the casing. For rigid bearing machines, a standard relative monitor is sufficient.
❗ Sensor Matching: Ensure your field seismic transducer matches the “Seismoprobe, no relay” configuration. Using a Velomitor or a quad-relay sensor requires a completely different part number.
Keep these in mind and you’ll cut 90% of rework time.
