Bently Nevada|126623-01| Aero GT I/O Module
Description
The Bently Nevada 126623-01 is an Aero GT I/O Module with External Terminations, designed for use with the 3500/44M Aeroderivative Monitor. It interfaces with velocity transducers and accelerometers to provide precise vibration monitoring for aeroderivative gas turbines.
Features
- Vibration Monitoring: Interfaces with Velomitor sensors and accelerometers.
- Configurable Filters: Supports signal integration, 1X vibration tracking, and band-pass vibration.
- Keyphasor Signals: Accepts inputs from two separate Keyphasor signals for accurate tracking.
- External Termination: Provides flexibility in installation and connection.
Technical Specifications
- Model Number: 126623-01.
- Channels: Up to 4 channels.
- Input Signal Types: Velocity transducers, accelerometers, Velomitors.
- Input Impedance: Greater than 95 kΩ for Aero GT I/O; 10 kΩ for Prox/Accel, 3.5 MΩ for Velomitor.
- Power Consumption: 7.7 watts typical.
- Sensitivity: 3.94 mV/(mm/s) or 5.71 mV/(mm/s).
- Outputs: Buffered transducer outputs with short-circuit protection, recorder outputs proportional to full-scale.
- Output Impedance: 550 Ω.
- Transducer Power Supply: -23 Vdc nominal at 43 mA max.
- Voltage Compliance: 0 to +12 Vdc range across load (0 to 600 Ω).
- Resolution: 0.3662 µA per bit, ±0.25% error at room temperature, ±0.7% over temperature.
- Update Rate: 100 ms or less.
-
Frequency Response:
- Direct signal: 4 Hz to 30 kHz (-3 dB).
- Band-pass filter: Low-pass corner at 200 Hz, high-pass corner configurable between 10 Hz and 1000 Hz.
- Tracking filter valid for machine speeds of 60 to 240,000 cpm.
- Constant Q: User-configurable by selecting one of 22 normal operating speeds from 2,400 to 18,000 RPM, bandwidth of 3 or 5 Hz.
- Rolloff: 6-pole (120 dB per decade, 36 dB per octave).
- Accuracy: Within ±0.33% of full-scale typical, ±1% maximum.
-
Environmental Limits:
- Operating Temperature: -30°C to +65°C (-22°F to +150°F).
- Storage Temperature: -40°C to +85°C (-40°F to +185°F).
- Humidity: 95%, non-condensing.
- Alarms: Configurable Alert and Danger setpoints, adjustable from 0 to 100% of full-scale, accuracy within 0.13% of desired value.
- Dimensions: 241.3 mm x 24.4 mm x 99.1 mm (9.50 in x 0.96 in x 3.90 in).
- Weight: 0.45 kg (1.0 lb).
