Product function
Bently Nevada 135137-01 provides stable AC excitation to LVDTs, eliminating external oscillators. Demodulates differential outputs, linearizes position signals, and digitizes data with 16-bit resolution. Compares positions against programmable limits for over-travel alarms and continuously monitors loop integrity.
Application Areas
Turbine Thrust Bearing Monitoring: Real-time axial position tracking using Bently Nevada 135137-01 to prevent rubs
Reciprocating Rod & Piston Position: Stroke/dwell-time monitoring in engines/compressors
Valve Position Feedback: Precise control for process valves
Generator End-Winding Expansion: Axial movement monitoring under thermal growth
Condition-Based Maintenance: Trend-analysis via Bently Nevada 135137-01 for predictive service scheduling
