Description
The Bently Nevada 3300/25 Dual Accelerometer Monitor is a high-performance, rack-mounted module engineered for the 3300 Series monitoring system. This unit provides two independent channels specifically designed for tracking casing vibration using accelerometer inputs. By continuously monitoring vibration levels against pre-configured alarm setpoints, it ensures the protection of critical rotating machinery such as turbines, compressors, motors, and pumps.
Features
- Dual-channel configuration for independent monitoring and redundancy.
- Continuous vibration signal processing with real-time comparison to Alert and Danger setpoints.
- Integrated status LEDs for visual monitoring of OK, Bypass, Alert, and Danger conditions.
- Provides dynamic vibration signal output and proportional 4-20 mA signals for integration into external control systems.
- Standard relay outputs facilitate automated shutdown or warning sequences during abnormal operation.
Applications
This monitor is primarily utilized in industrial environments for the protection of critical assets, including large industrial pumps, centrifugal compressors, fans, and steam or gas turbines where casing vibration monitoring is essential for predictive and preventative maintenance.

Installation Guidelines
- Ensure the 3300 rack is powered down before inserting or removing the monitor module to prevent electrical damage.
- Verify that the module is correctly seated in the rack slot and that all rear-panel connections are secure.
- Use shielded cables for all transducer inputs to minimize electromagnetic interference (EMI) in industrial environments.
- Adhere to proper grounding practices for the 3300 system to ensure signal integrity and safety compliance.
- Ensure adequate ventilation around the rack to maintain operating temperatures within the specified -30 degC to +65 degC range.
FAQ
What is the primary function of the 3300/25 monitor?
It is designed to measure and monitor casing vibration using accelerometer sensors to protect rotating machinery from damage.
Does this module include intrinsic safety barriers?
No, the 00 suffix for the barrier option indicates this specific configuration does not include internal intrinsic safety barriers.
What do the LED indicators represent?
The LEDs provide immediate visual feedback regarding the module's health (OK), current relay status (Alert/Danger), and maintenance state (Bypass).
