1. General Description
The Bently Nevada 3500/50-01-01-00-00 is a high-precision, dual-channel tachometer module for the 3500 Series machinery protection system. It monitors rotational speed (RPM), acceleration, and shaft direction on critical rotating machinery (turbines, compressors, pumps, motors). It accepts inputs from proximity probes or magnetic pickups and drives alarms via the 3500 system relay modules.
2. Key Specifications
• Channels: 2 independent speed inputs
• Measurement Range: 0 ~ 99,999 RPM
• Input Sensors: Proximity probes (eddy current), magnetic pickups
• Accuracy: ±0.1 RPM (≤100 RPM); ±1 RPM (100–10,000 RPM); ±0.01% (>10k RPM)
• Output: 4–20 mA (recorder); relay alarm (via 3500 system)
• Power: 5.8W typical; 24Vdc from 3500 rack
• Temp: -40°C ~ +85°C
• Certifications: CSA/NRTL/C, CE, UL
3. Core Features
• Dual-Channel: Two isolated speed/phase inputs
• Speed Bands: Programmable alarm setpoints (over-speed, under-speed)
• Zero Speed Detect: Indicates shaft stationary state
• Acceleration Monitor: Detects rapid speed changes
• Reverse Rotation: Alarms on reverse shaft motion
• Key Phasor: Provides once-per-rev timing for vibration analysis
• Internal Terminations: -01 = built-in I/O wiring terminals
• CSA Certified: Suitable for industrial hazardous locations
4. Typical Applications
• Steam/gas turbines, centrifugal compressors
• Pumps, fans, motors, gearboxes
• Turbo generators, industrial rotating equipment
• TSI (Turbine Supervisory Instrumentation)
• Critical machinery in power, oil/gas, refining, paper
