The Bently Nevada 3300/25-01-03-03-00-00-03-00 is a dual-channel accelerometer monitor designed for integration within the 3300 Series machinery protection system. This module provides continuous monitoring of casing vibration, serving as a critical protection component for rotating equipment such as industrial turbines, large compressors, motors, and pumps. By processing inputs from two independent accelerometer sensors, the unit compares real-time vibration data against pre-configured alarm setpoints to trigger protective actions when thresholds are exceeded.
Features
Dual independent channels for high-density monitoring of casing vibration.
Configured for accelerometer transducer inputs.
Provides proportional 4-20 mA outputs for integration with external control systems or data recorders.
Integrated relay outputs for Alert and Danger alarm conditions.
Front-panel LED indicators for immediate visual status monitoring, including OK, Bypass, Alert, and Danger states.
Standard configuration with no internal intrinsic safety barriers.
Applications
This monitor is specifically engineered for critical asset protection in heavy industrial environments, including power generation, oil and gas, and petrochemical facilities. It is primarily used to detect structural vibration issues that could lead to mechanical failure in rotating machinery.

Installation Guidelines
Ensure the 3300 system rack is properly grounded before installing the module.
Always power down the rack or relevant slot before inserting or removing the monitor to prevent electrical damage.
Use shielded cabling for all transducer inputs to minimize electromagnetic interference (EMI) in industrial environments.
Verify that the configuration switches match the intended application requirements before final deployment.
Maintain proper ventilation in the equipment cabinet to ensure the module operates within its specified temperature range.
Handle with care to prevent electrostatic discharge (ESD) damage to the internal circuitry.
FAQ
What is the primary function of this module?
The 3300/25 monitor is designed to process signals from accelerometers to measure casing vibration, providing alarm and shutdown capabilities for critical rotating machinery.
Are the alarm setpoints configurable?
Yes, the 3300 series monitors allow for field-configurable alarm setpoints to match the specific vibration requirements of the protected machine.
Does this unit include internal safety barriers?
No, the suffix code 00 for the barrier option indicates that this specific unit does not include intrinsic safety barriers.
