Product Overview

The Bently Nevada 108000-02 is a specialized 108 series data acquisition instrument engineered for sophisticated vibration analysis and machinery diagnostics. This multi-channel hardware serves as a portable or semi-permanent diagnostic hub, allowing engineers to capture high-resolution seismic and proximity data from rotating assets. Unlike standard monitors, the 108 series is designed for deep-dive analytical tasks, such as Hot-Align analysis, which identifies thermal growth and alignment shifts in real-time. By interfacing directly with transducers, the 108000-02 provides the raw data necessary for identifying complex mechanical faults, including rotor instabilities, structural resonance, and bearing degradation in high-stakes industrial environments.

Industrial Operational Scenarios

This acquisition instrument is a staple for machinery diagnostic engineers working in the following fields:

• Precision Alignment: Utilizing the "Hot-Align" feature to track shaft position changes as machinery transitions from cold start to peak operating temperature.

• Transient Data Capture: Recording vibration signatures during machine startup and coast-down to identify critical speeds and resonance peaks.

• Troubleshooting Heavy Assets: Temporary installation on steam turbines, large centrifugal compressors, and gearbox housings to isolate intermittent vibration issues.

• Refinery Condition Monitoring: Executing field-based diagnostics in extreme weather conditions, thanks to its wide -50°C to +120°C operating range.

FAQ

Q: Is the 108000-02 intended for permanent machinery protection?

A: No, while it provides monitoring data, the 108 series is primarily an "Acquisition Instrument" used for diagnostic analysis and alignment. For continuous 24/7 automatic machinery tripping, the 3500 series rack is the industry standard.

Q: What is the benefit of the Hot-Align analysis feature?

A: Hot-Align allows engineers to measure how much a machine's alignment changes due to thermal expansion. This ensures that the machine is perfectly aligned at its actual operating temperature, preventing bearing wear.

Q: Does this instrument require a laptop to function?

A: While it can interface with diagnostic software via its serial port, the 108000-02 features an integrated LED display and front-panel controls for basic setup and data viewing in the field.

Q: Can this unit handle inputs from different types of sensors at once?

A: Yes, the 8-channel input configuration is versatile and can typically accept signals from proximity probes, accelerometers, and velocity transducers depending on the setup configuration.

Q: What type of power source is required for field use?

A: The unit operates on a standard 24V DC loop (18 to 30 VDC), making it compatible with most industrial power supplies or portable battery packs used by diagnostic teams.
