Bently Nevada 3500/61 Core Function

Hybrid Sensor Fusion Capability

The Bently Nevada 3500/61 uniquely processes mixed RTD and thermocouple inputs on a single module when using non-isolated I/O. Configurable per channel via firmware, it enables cost-efficient monitoring of bearing RTDs alongside turbine exhaust TCs without separate hardware .

Dynamic Ambient Compensation Limitations

Integrated cold-junction compensation achieves ±1°C accuracy only when ambient temperature remains stable (±2°C/hr). Rapid shifts in enclosure temp induce ±3°C TC measurement drift—critical for gas path monitoring requiring dedicated CJC modules .

Fault-Tolerant TMR Architecture Mandate

For Triple Modular Redundant safety systems, three Bently Nevada 3500/61 modules must occupy consecutive rack slots to enable cross-channel voting logic. Non-adjacent installation disables the "2-out-of-3" trip redundancy .
