The Bently Nevada 3300/55-01-04-02-02-03-00-05-00 is a specialized Dual Velocity Monitor module engineered for the 3300 Series machinery protection system. This unit provides reliable, continuous monitoring of casing vibration velocity by interfacing directly with Velomitor piezo-velocity sensors. It features two independent channels that process vibration signals to identify potential mechanical issues, offering both proportional output signals and relay-based alarm logic for automated machine protection.
This module is primarily utilized in critical industrial rotating machinery applications, including turbines, compressors, fans, and pumps where casing vibration velocity is a key indicator of structural or mechanical health.
| Model | 3300/55-01-04-02-02-03-00-05-00 |
| Series | 3300 |
| Inputs | 2 x Velomitor piezo-velocity sensor channels |
| Outputs | 4-20 mA proportional, Relay (Alert/Danger) |
| Power Consumption | 1.5 W (typical) |
| Operating Temperature | 0 degC to 60 degC |
The 3300/55 is designed to measure casing vibration velocity using piezo-velocity sensors, comparing these values against pre-set alarm limits to trigger protective relays for machinery shutdown or operator notification.
Yes, this specific configuration (indicated by the 03 barrier option) includes intrinsic safety barriers intended for use in hazardous environments, provided all installation requirements are met.
The LEDs provide immediate visual diagnostics, including the OK status of the sensor/module, Bypass status for maintenance, and the current Alert or Danger alarm state for each channel.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
