The 3300/15-03-01-01-00-00-00 is a dual-channel radial vibration monitoring module in the Bently Nevada 3300 series. It converts raw eddy current probe signals into high-accuracy digital and analog outputs, enabling real-time detection of shaft imbalance, misalignment, or bearing wear.
This module features a local front-panel display for immediate operator feedback and is compatible with legacy high-sensitivity proximity systems. Its hardware-centric architecture ensures continuous machinery protection, even if external networks fail.

Ideal for high-sensitivity displacement monitoring in fluid-film bearing systems, where early detection of vibration changes prevents catastrophic failure.
Why is the 7200 mV/mm scale factor important?
It allows extremely fine-resolution detection of shaft movement, essential for precision machinery using high-sensitivity sensors.
How does the 4–20 mA output work with the front-panel display?
The display provides local, real-time readings for on-site troubleshooting, while the 4–20 mA output transmits the same signal to DCS or PLC systems for long-term trend logging and remote monitoring.
