The Bently Nevada 3300/55 Dual Velocity Monitor is a precision-engineered module designed for the 3300 series rack systems. This unit provides continuous monitoring of casing vibration by interfacing with Velomitor piezo-velocity sensors. It is primarily utilized in critical machinery protection applications, such as monitoring turbines, compressors, motors, and pumps, by evaluating vibration velocity against pre-configured alarm setpoints to trigger protective actions.
Features
Dual-channel velocity measurement architecture for redundant or independent monitoring.
Direct compatibility with industry-standard Velomitor piezo-velocity sensors.
Configurable alarm setpoints for Alert and Danger status levels.
Integrated relay outputs for automated machinery trip sequences.
Proportional 4-20 mA output signals for seamless integration with DCS or PLC control systems.
Designed for high-reliability operation in demanding industrial environments.

Installation Guidelines
Ensure the 3300 rack is powered down before inserting or removing any I/O modules to prevent electrical damage.
Verify that the module is fully seated and the front panel screws are tightened to ensure proper backplane connection.
Use shielded cabling for all transducer inputs to minimize signal interference and electromagnetic noise.
Ensure that the transducer signals are correctly routed according to the specific wiring diagram for the 3300/55 configuration.
Maintain proper ventilation in the rack enclosure to ensure the module operates within its specified temperature range.
Handle modules using standard ESD (Electrostatic Discharge) precautions to protect sensitive internal circuitry.
FAQ
What type of sensors does this module support?
The 3300/55-01-04-18-18-00-00-05-00 is specifically configured to accept inputs from Bently Nevada Velomitor piezo-velocity sensors.
Does this module include intrinsic safety barriers?
No, the '00' barrier option in the model code indicates this unit is configured for standard input without internal intrinsic safety barriers.
What is the primary function of the relay outputs?
The dual relay outputs are designed to actuate based on programmed Alert and Danger alarm setpoints, facilitating automatic machinery shutdown or warning alerts during abnormal vibration events.
