176449-04 | Bently Nevada | 3500/45 Position Monitor

The 3500/45 Position Monitor is a versatile 4-channel instrument designed for monitoring and analyzing machinery position parameters. It supports various input devices and is engineered to provide both machinery protection and operational insights.

Key Features:

1. Multi-Input Capability:
   • Accepts inputs from Proximity Transducers, Rotary Position Transducers (RPTs), DC/AC Linear Variable Differential Transformers (LVDTs), and rotary potentiometers.
2. Customizable Functions:
   • Each channel can be configured for:
     • Axial (Thrust) Position
     • Differential Expansion (Single/Dual Ramp, Complementary)
     • Case Expansion
     • Valve Position
3. Machinery Protection:
   • Continuously monitors parameters against user-configured alarm thresholds, providing early detection of issues.
4. Data Insight:
   • Offers valuable information for operations and maintenance personnel, with real-time measurements and alarms.
5. Accurate Signal Processing:
   • Conditions input signals and compares them to user-defined thresholds, generating reliable alerts.
