Bently Nevada 3300/03-02-00 System Monitor

Bently Nevada 3300/03-02-00 is one of the 3300 series system monitors, mainly used for monitoring parameters such as vibration and displacement of industrial rotating machinery to ensure the safe operation of equipment. The following is a detailed analysis from the aspects of function, technical parameters, application scenarios, etc.:

1. Model analysis

The 3300 series models are usually named according to "functional module + configuration parameters". The meanings of each part of this model are as follows:

3300: represents Bently Nevada's classic 3300 mechanical protection system series;

03: may indicate the module type (such as vibration monitoring module);

02-00: represents specific configuration parameters (such as measurement range, number of input channels, etc., which need to be confirmed in conjunction with the official manual).

2. Core functions

Vibration monitoring

Supports measurement of shaft vibration (radial, axial), housing vibration, etc., and real-time monitoring of mechanical operation status;

Can be connected to eddy current probes, acceleration sensors, etc., and is suitable for steam turbines, compressors, motors and other equipment.

Data processing and alarm

Filter, amplify, and analyze the spectrum of vibration signals, and output parameters such as effective value (RMS) and peak value;

Support multi-level alarm settings (such as warning, danger), and trigger shutdown protection through relay contacts or analog signals.

System integration

Compatible with other modules of the 3300 series (such as speed module, displacement module) to form a complete mechanical protection system;

Can communicate with DCS (distributed control system) or PLC to achieve remote monitoring and data sharing.

3. Technical parameters (refer to similar products)

Parameter type Typical value

Input channel 1 or 2 channels (support dual-channel redundancy)

Measurement range Vibration displacement: ±500μm (customizable)

Frequency response 0.1Hz~10kHz (covering the vibration frequency band of rotating machinery)

Output signal - Analog: 4~20mA or -20V~0V

- Digital: relay contact (dry contact)

Power supply voltage 24V DC (±10%)

Operating temperature -40℃~+70℃ (adaptable to industrial environment)

Protection level Installed in the control cabinet, usually IP20

4. Installation and structure

Modular design

Standard 19-inch rack installation, can be inserted into the 3300 frame (such as 16-slot or 32-slot frame), and used side by side with other modules;

The front panel is equipped with indicator lights (power, alarm, fault) and test interfaces for easy on-site debugging.

Wiring method

Input: connect to the probe preamplifier (such as 3300 eddy current probe system);

Output: connect to external alarm equipment or control system through terminal block.

V. Application scenarios

Key industries

Petrochemical: monitor the shaft vibration of cracking gas compressors and pump units to prevent bearing failure;

Electric power: used for vibration protection of steam turbine generator sets to avoid rotor collision and other faults;

Metallurgical manufacturing: monitor the operating status of rolling mill main motors and fans to reduce unplanned downtime.

Supporting system

Often used with Bently Nevada 3300 series probes (such as 330102 eddy current probes), extension cables (330130) and preamplifiers (330180) to form a complete mechanical health monitoring solution.
