Basic Product Information
Manufacturer: Bently Nevada; Product No.: 3500/42-02-00; Product Type: Proximitor Seismic Monitor. It is manufactured in the U.S.A. with I/O Module Type 02 and no hazardous area approval (Option 00 = None).
Transducer Type: Seismoprobe is recommended; Proximitor, Accel, and Velomitor are supported but not advised. The monitor is part of the 3500 Series and classified under I/O Modules in product categories.
Input Specifications
The 3500/42-02-00 accepts 1 to 4 proximity, velocity, or acceleration transducer signals for comprehensive monitoring. Its typical power consumption is 7.7 watts, ensuring efficient energy use in industrial setups.
Input Impedance: Standard I/O features 10 kΩ for Proximitor and acceleration inputs, ensuring stable signal reception without interference. This impedance level matches most industrial transducer outputs for seamless integration.
Sensitivity Parameters
Radial Vibration: 3.94 mV/μm (100 mV/mil) or 7.87 mV/μm (200 mV/mil), providing precise detection of vibration changes. Thrust and Eccentricity share the same sensitivity options as radial vibration.
Differential Expansion: 0.394 mV/μm (10 mV/mil) or 0.787 mV/μm (20 mV/mil), suitable for measuring small expansion changes in industrial equipment. REBAM: 40 mV/μm (1000 mV/mil) or 80 mV/μm (2000 mV/mil) for high-sensitivity applications.
Acceleration & Acceleration2: 10 mV/(m/s²) (100 mV/g), ensuring accurate measurement of acceleration levels. Velocity & Velocity2: 20 mV/(mm/s) pk (500 mV/(in/s) pk), 5.8 mV/(mm/s) pk (145 mV/(in/s) pk), or 4 mV/(mm/s) pk (100 mV/(in/s) pk).
Shaft Absolute, Radial Vibration and Direct: 3.94 mV/μm (100 mV/mil) or 7.87 mV/μm (200 mV/mil). Shaft Absolute, Velocity shares the same sensitivity options as standard Velocity.
Output Specifications
Front Panel LEDs: OK LED indicates normal operation; TX/RX LED shows communication with other 3500 rack modules; Bypass LED signals Bypass Mode activation. These LEDs provide quick visual status updates for operators.
Buffered Transducer Outputs: Each channel has a front-mounted coaxial connector, all short-circuit protected. Output Impedance is 550 Ω, ensuring stable signal transmission to external devices.
Transducer Power Supply: -24 Vdc, compatible with most industrial transducers. Recorder Output: +4 to +20 mA, values proportional to monitor full-scale, with individual recorder values for each channel.
Voltage Compliance (current output): 0 to +12 Vdc range across load; load resistance 0 to 600 Ω. Monitor operation remains unaffected by short circuits on recorder outputs.
Resolution: 0.3662 µA per bit, with ±0.25% error at room temperature and ±0.7% error over the operating temperature range. Update rate is approximately 100 ms or less for real-time data.
Shaft Absolute Buffered Outputs: One output per channel group, all short-circuit protected. Shaft Absolute Output Impedance is 300 Ω for reliable signal transmission.
Acceleration & Acceleration2 Accuracy: ±0.33% of full-scale typical, ±1% maximum (excluding filters). Filter Quality: High-pass and Low-pass are 4-pole (80 dB per decade, 24 dB per octave).
Acceleration II Frequency Response: Bias filter -3 dB at 0.01 Hz; Not OK filter -3 dB at 2400 Hz. 1X and 2X vector filter: Valid for 60 cpm to 100,000 cpm machine speeds.
Velocity & Velocity II Accuracy: ±0.33% of full-scale typical, ±1% maximum (excluding filters); +1% to -3% with MTL 764(-) Zener External Barrier.
Velomitor Sensor Accuracy: Full Scale 0-0.5: ±3% typical; 0-1.0: ±2% typical; 0-2.0: ±1% typical. With barriers (radiated immunity): ±11% added, total ±15%.
Velocity & Velocity II Frequency Response: Bias (Velocity II only) -3dB at 0.01 Hz; Not OK filter (Velocity II only) -3 dB at 40 Hz. RMS: 10 to 5,500 Hz, -3 dB; Peak/Peak-to-Peak: 3 to 5,500 Hz, -3 dB.
Velocity II 1X and 2X vector filter: Valid for 60 to 100,000 cpm machine speeds. Filter Quality: High-pass 4-pole (80 dB per decade, 24 dB per octave); Low-pass 2-pole (40 dB per decade, 12 dB per octave).
