Bently Nevada 3500/42E-00-00 Vibration Monitor 285691-01 Proximitor Seismic Monitor 4 Channel

Bently Nevada 3500/42E-00-00 Vibration Monitor 285691-01 Proximitor Seismic Monitor

Product Overview
The Bently Nevada 3500/42E is the latest generation of GE's 3500 series, a 4-channel universal monitor (Enhanced Monitor). It accepts eddy current sensors, velocimeters, accelerometers, or combination sensors to provide real-time measurement of radial vibration, axial displacement, eccentricity, differential expansion, acceleration, velocity, absolute shaft vibration, and REBAM® parameters. The module utilizes an enhanced DSP and 24-bit ADC, delivering a dynamic range of >100 dB and a frequency response of 0.5 Hz–10 kHz. It meets API 670 machinery protection and IEC 61508 SIL2/SIL3 requirements for critical equipment such as turbines, compressors, fans, pumps, gearboxes, and motors.

Core Features
• 4 Independently Configurable Channels: Each channel can be configured as displacement, velocity, or acceleration, supporting a variety of sensor combinations.
• Dual Alarm + Danger Setpoint: Each channel has 2 alarm and 2 danger relay outputs, with programmable delays from 0–60 seconds.
• Adaptive Filtering: Real-time speed tracking and automatic filter switching prevents false alarms at critical speeds.
• Hot Swapping: Online module replacement with zero downtime; automatic configuration upload/download for maintenance in less than 2 minutes.
• TMR Ready: Compatible with the 3500/53M and 3500/60 sensors for a 3x2oo3 voting system, enhancing safety integrity.
• System 1 Integration: Upload waveforms, spectra, and trends to System 1 software via the 3500/92 Communication Gateway or 3500/22 TDI for predictive maintenance.

Technical Specifications
Input Signals:
• Eddy Current Sensors: 3300 XL 5/8 mm, 3300 XL 11 mm

Accuracy: ±1 % FS (25°C)
Frequency response: 0.5 Hz–10 kHz (–3 dB)
Outputs:
• 4 × 4–20 mA isolated current (optional)
• Buffered raw signal output BNC (front panel)
• Real-time waveform/spectrum via Ethernet (requires 3500/92)
Relays: 6 × SPDT, 30 V DC / 5 A; supports channel cross-voting
Operating temperature: –40°C to +70°C
Enclosure rating: IP20 (inside chassis)

Typical applications
• Refinery catalytic cracking main blower: radial vibration + Shaft displacement interlock shutdown
• LNG terminal BOG compressor: Acceleration envelope monitoring for early bearing damage
• Nuclear power plant main feedwater pump: Differential expansion + speed TMR voting to meet nuclear safety requirements
• Offshore platform gas turbine: Integrated shaft absolute vibration + temperature monitoring to reduce unplanned downtime
