Comparison with similar models and alternatives
Model |
Functional Differences |
Advantages/Disadvantages Comparison |
3500/42M |
Dedicated vibration monitoring (shaft/housing vibration), FFT spectrum analysis |
Superior for dynamic vibration analysis, but cannot cover position monitoring; Complementary deployment with Bently Nevada 3500/45. |
3500/45 TMR |
Redundant version (requires 03/04 I/O modules), supports triple voting |
Enhanced reliability (MTBF > 75 years), but 30% higher cost and valve position function disabled. |
