3500/46M 176449-06 4-Channel Hydro Monitor Module for Hydropower Turbine Vibration and Air Gap Protection
Product Overview
The Bently Nevada 3500/46M 176449-06 is a four-channel hydro monitor module for turbine protection. It processes signals from proximity, seismic, dynamic pressure, and air gap sensors.
- 4 Channels: Monitors radial vibration, thrust, and air gap
- Shear-Pin Detection: Combines shaft gap with NX amplitude to catch failures
- Multimode Alarms: Stores 8 mode-specific alarm sets to prevent false trips
Technical Guidance: Program channels in pairs. Mask electromagnetic noise because the 0.104 Hz low-frequency response is highly sensitive.
Field Application: Used in pumped-storage plants for stator end winding (SEW) protection.

Technical Q&A
What is the 3500/46M 176449-06 used for?
Usually found on low-speed Francis and Kaplan hydro units, this 4-channel Hydro Monitor Module accepts signals from proximity probes, seismic sensors and air gap sensors. One card handles Hydro Radial, Hydro Thrust and SEW monitoring, so a 3500 Rack often needs fewer monitoring modules.
Why does the 3500/46M 176449-06 work well on low-speed machines?
Low-frequency signals can easily cause nuisance trips. Rather than using fixed processing, the module measures down to 0.104 Hz and lets Multimode Alarms change with the operating mode, which helps avoid unnecessary Alert or Danger alarms.
What faults can the 3500/46M 176449-06 identify?
Besides routine dynamic monitoring, it also checks for Shear-Pin Failure. Air Gap information is evaluated together with NX Amplitude, making developing mechanical issues easier to spot before they interrupt operation.
What works with the 3500/46M 176449-06?
A typical system combines the module with a 3500/05 Rack and a 3500/22M TDI. Either 140471-01 or 140482-01 Prox/Velom I/O can be used, while 3500 Rack Configuration and System 1 are usually chosen for setup and condition monitoring.
