3500/40M 140734-01 multi-channel machinery protection monitor

1. Basic Information

• Brand: Bently Nevada
• Model: 3500/40M
• Part Number: 140734-01
• Product Type: Multi-channel Machinery Protection Monitor (for 3500 Series System)
• Form Factor: Full-height module (occupies 1 front slot and 1 rear I/O slot in 3500 system racks)
• Core Role: Collects, conditions, and analyzes sensor signals to monitor key mechanical parameters, trigger alarms/trips, and ensure safe operation of equipment.

2. Core Functional Features

• Multi-Parameter & Multi-Sensor Compatibility: Supports input signals from multiple sensor types to monitor a wide range of mechanical parameters:
  • Eddy current proximity probes: For radial vibration, axial thrust position, differential expansion, and eccentricity (critical for rotating shafts).
  • Velocity/acceleration sensors: For bearing housing vibration and structural vibration (common in reciprocating compressors or fans).
  • Thermocouples/RTDs (optional): For bearing temperature monitoring (via auxiliary I/O modules).
• 4-Channel Independent Monitoring: Equipped with 4 fully independent monitoring channels, each with dedicated signal conditioning circuits. This design ensures that a fault in one channel (e.g., sensor disconnection) does not affect the operation of other channels, maximizing system reliability.
