Functional Description

3300/15 is a Dual Vibration Monitor developed by Bently Nevada. It is a part of 3300 Bently Nevada Series. The Dual Vibration Monitor is a microprocessor-based monitor with digitally adjustable Alert and Danger thresholds. For radial vibration amplitude, each channel has its own Alert and Danger alarm setpoints. It has status indicators (monitor and transducer OK, Alert, Danger, and Bypass) as well as independent per channel peak to peak amplitude detection of vibration signals for continuous display and driving recorder outputs. The rear terminal strip delivers short-circuit-protected power to the two transducer systems. The OK circuit continuously monitors the cach transducer and associated field wiring operation. On the monitor's LCD readout, both channels are continuously displayed independently.


  • It is suitable for virtually all types of rotating and reciprocating machinery and provides sophisticated on-line vibration monitoring. It can continuously measure and monitor two independent radial vibration channels while accepting input from two proximity probe transducer systems.
  • The product works in conjunction with the 3300 System Rack, Power Supply, and System Monitor, which are all ordered separately.
  • The American Petroleum Institute Standard is met by the Dual Vibration Monitor.


  • Quality, dependability, and flexibility are built into 3300 monitors.
  • Each monitor operates independently within the system, requiring no additional control panel, keyboard, or programming module. The Dual Vibration Monitor includes features that optimize long-term, dependable, and highly accurate system operation. These characteristics are critical, especially in installations where the monitoring system serves as an input to an automatic machine shutdown system.
  • It is not always possible to determine the exact monitor options you will require for a specific application when placing your order. The Dual Vibration Monitor includes a variety of plug-in (user-programmable) jumpers, allowing you to easily set the appropriate monitor options when you receive the system. These options can be changed in the field if necessary in the future. Jumper programming does not necessitate the use of any tools or extra parts.
  • These are plug-in jumpers that can be adjusted manually. The on-board microprocessor reads the jumper positions and controls the monitor accordingly.
