GE / Bently Nevada ADRE-208 Data Acquisition Interface

The GE / Bently Nevada ADRE-208 Data Acquisition Interface is a portable multi-channel system engineered for machinery condition monitoring and real-time vibration diagnostics. It captures dynamic transducer signals, static process variables, and speed inputs - consolidating the functionality of oscilloscopes, spectrum analyzers, filters, and recording instruments into a single portable unit. The ADRE-208 processes time-domain and frequency-domain data with high resolution sampling, eliminating the need for multiple specialized instruments on-site.

Technical Specifications

Channels: Up to 16 simultaneous acquisition channels

Input Signal Types: Dynamic transducer signals (proximity probes, velocity transducers, accelerometers, dynamic pressure sensors); static signals (process variables); Keyphasor® or speed input signals

Data Acquisition: Time-domain and frequency-domain capture; high-resolution sampling for dynamic vibration data

Signal Processing: Real-time analysis with integrated oscilloscope, spectrum analyzer, filter, and recording capabilities

Analysis Tools: Time waveform analysis, frequency spectrum analysis, orbit analysis, phase analysis

Data Storage: Built-in storage for vibration data and analysis results

Operating Temperature: 0°C to +50°C (+32°F to +122°F)

Power Supply: AC or battery operation

Amplitude Accuracy (at +25°C): ±0.77% of input signal and ±0.28% of full-scale range (100 to 60k rpm); ±0.49% of full-scale range across operating temperature range

Key Features

Portable design for field deployment

Multi-format input compatibility eliminates adapter proliferation

Real-time signal processing for immediate diagnostics

Unified oscilloscope and spectrum analyzer functionality

Connectivity Two variants support different interface architectures: ADRE-208 connects to legacy Compaq notebook docking ports and desktop systems via ISA card; ADRE-208-P interfaces directly to enhanced parallel ports (EPP) found on modern notebooks and desktops. These two units cannot be daisy-chained together.

Typical Applications Rotating machinery health monitoring, bearing condition assessment, turbomachinery vibration analysis, and predictive maintenance programs across 100 to 60k rpm operational ranges.
