The 3300/55-03-14-14-14-00-00-07-00 is a dual-channel seismic velocity monitoring module for the Bently Nevada 3300 System. It is designed to monitor casing vibration and structural vibration on rolling-element bearing machinery by measuring vibration velocity (rate of displacement change), which improves detection of mid-frequency mechanical faults.
Each channel operates independently with built-in signal conditioning and alarm logic. The module also supports 4-20 mA analog outputs for integration with DCS or PLC systems for continuous monitoring and data logging.

The module is commonly used to detect looseness, imbalance, and misalignment.
What does the -14-14-14 configuration mean?
It defines measurement range and filtering parameters. This configuration is optimized for 0–1.0 in/s velocity scale monitoring.
Can it support accelerometers?
No. The 3300/55 is designed for velocity transducers. Accelerometer monitoring requires a different module such as a 3300/50 series device.
