The 3300/16-15-01-01-00-00-01 is a dual-channel radial vibration and shaft position monitor within the Bently Nevada 3300 rack system. It converts signals from proximity probes into precise displacement measurements, enabling real-time detection of imbalance, misalignment, or bearing wear.
This module is optimized for 0–10 mils peak-to-peak full-scale range, making it ideal for large fluid-film bearing machines such as steam turbines, centrifugal compressors, and industrial fans. With a response latency under 1 millisecond, it ensures rapid trip signals to prevent catastrophic equipment damage.

Turbine Supervisory Instrumentation (TSI) in power plants
Oil refineries and chemical processing facilities
Monitoring fluid-film bearing machines, including large centrifugal compressors, steam turbines, and industrial fans
Critical for early detection of radial shaft movement to prevent equipment failure
Can this module work with older 7200 series Proximitor sensors?
Yes. It is backward compatible, provided the scale factor (mV/mil) is correctly calibrated to match the monitor’s input range.
How does supply voltage affect measurement accuracy?
Designed for a -24 V supply. Operating above -23 V may reduce the linear range of the proximity probe and affect high-vibration measurement accuracy.
