Function Description:

The 3500/46M 140471-01 Hydro Monitor is a specialized four-channel instrument designed for monitoring machinery in hydro applications. Here are the key features and functionalities of this monitor:

Sensor Inputs:

  • Accepts input from proximity, seismic, dynamic pressure, and air gap sensors.

140471-01 Conditioning and Measurements:

  • Conditions the input signals to provide vibration, position, and both static and dynamic pressure measurements.
  • Compares the conditioned signals with user-programmable alarms.

140471-01 Measurement Channels:

  • Hydro Radial Vibration
  • Hydro Air Gap
  • Hydro Velocity
  • Hydro Acceleration
  • Hydro Thrust
  • Multimode Hydro RV (Radial Vibration)
  • Multimode Air Gap
  • Multimode Hydro Velocity
  • Multimode Thrust
  • Multimode Acceleration
  • Multimode Hydro Dynamic Pressure
  • Hydro Stator End Winding (SEW)

140471-01 Hydro Radial Vibration Channels:

  • Combines shaft gap movement with the NX amplitude to provide a measurement for alarming on shear-pin failure.


  • Configurable using the 3500 Rack Configuration Software.


  • Provides machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms.
  • Offers essential machine information for operations and maintenance personnel.

Hydro Velocity Channels:

  • Provides early warning of pending machinery problems and assists in diagnosing them.
  • Cannot be used for automated machinery protection due to the nature of high amplitude, low-frequency velocity events.

Channel Configuration:

  • Each channel conditions its input signal to generate various parameters called static values.
  • Configurable alert setpoints for each active static value and danger setpoints for any two of the active static values.

Multimode Channels:

  • Configurable with up to eight sets of alarm parameters, including alert and danger setpoints, and alarm time delays.
  • Each set can be configured for a specific machine mode.

Mode Switching:

  • As the machine changes modes, the monitor can switch to a specific set using contacts on multimode I/O modules or software commands through a communications gateway.

In summary, the 3500/46M 140471-01 Hydro Monitor is a versatile monitoring system that provides detailed insights into the machinery’s condition in hydro applications. It offers a range of measurement channels and configuration options to suit different monitoring needs and modes of operation.
