3500/46M

Overview

• Model: 3500/46M
• Brand: Bently Nevada
• Type: Hydro Monitor

General Information

• The 3500/46M is a four-channel instrument that accepts input from proximity, seismic, dynamic pressure, and air gap sensors
• It conditions the signals to provide vibration, position, and both static and dynamic pressure measurements
• The monitor compares the conditioned signals with user-programmable alarms
• Hydro Radial Vibration channels combine shaft gap movement with NX amplitude for shear-pin failure detection

Inputs

• Signal: Accepts 1 to 4 proximity, air gap, velocity, or acceleration sensor signals
• Power Consumption: 7.7 Watts (typical)
• Multimode Positive Input I/O: 50 kΩ
• Input Impedance:
  • 10 kΩ for Proximity/Velocity I/O
  • 3.5 MΩ for Velomitor

Outputs

• Front Panel LEDs:
  • OK LED: Indicates proper operation
  • TX/RX LED: Indicates communication with other modules in the 3500 Rack
  • Bypass LED: Indicates Bypass Mode
• Buffered Transducer Outputs:
• • One coaxial connector for each channel
  • Short-circuit protected
  • Output Impedance: 550 Ω
