Bently Nevada 3300/50-01-02-03-02 Dual Velocity Monitor

System Integration and Primary Function

The 3300/50-01-02-03-02 is a high-reliability dual-channel velocity monitor designed for the Bently Nevada 3300 Machinery Protection System. Its primary objective is to provide continuous monitoring of vibration levels on rotating machinery using velocity transducers.

Technical Parameters and Operating Logic

• Module Type: Dual Velocity Monitor

• Number of Channels: Two independent monitoring channels

• Transducer Input: Specifically designed for velocity transducers with standard sensitivities

• Scale Range Option 01: 0 to 1.0 in/s peak

• Signal Output: Dual 4 to 20 mA proportional analog outputs for PLC or DCS integration

• Accuracy: Within plus or minus 1 percent of the full-scale range

• Alarm Delays: Field programmable from 0.1 to 60 seconds to mitigate transient signal interference

• Circuit Protection: Built-in OK Circuitry that monitors the health of the transducer and wiring

• Operating Temperature: 0 to 65 degrees Celsius

• Agency Approvals Option 02: CSA/NRTL/C Class I Division 2 certification for hazardous locations

Detailed Configuration Profile

The specific configuration for the 3300/50-01-02-03-02 is defined by the following hardware and firmware options:

Full-Scale Range 01: Configured for 0 to 1.0 inches per second (in/s) peak. This range is standard for monitoring general balance and alignment issues in industrial rotating assets.

Agency Approval 02: This unit meets North American standards for Class I, Division 2 groups A, B, C, and D, ensuring safe operation in environments where volatile gases may be present.

Relay and Recorder Option 03: Features Quad Relays providing independent Alert and Danger contacts for both channels. This allows for sophisticated logic voting and machinery trip integration.

Internal Termination 02: This hardware revision is designed for internal termination blocks, which optimizes cabinet space and improves vibration resistance for field wiring connections.
