Comparison with similar models and alternatives
Model |
Advantages |
Disadvantages |
Bently Nevada 3300/46 |
Ramp algorithm directly outputs expansion values; Reduces signal conversion errors |
Single-function monitoring; Does not support vibration/temperature integration |
3300/45 (Dual DE Monitor) |
Dual-channel redundancy; Supports complementary measurement modes |
Requires external slope calibrator; Increases configuration complexity |
Alternative: 3500/45E |
Integrated System 1® diagnostics; 50% higher channel density |
Requires 3500 rack replacement; Upgrade cost increases by 60% |
Alternative: 3701 ADAPT |
Distributed architecture; Supports wireless transmission |
Compatible with vib/tach only; Cannot monitor differential expansion parameters |
Upgrade suggestion:
The 3300 series has been discontinued (phased out in 2014), Bently Nevada 3300/46 users can migrate to the 3500/45E:
Advantages:The original probe compatibility is retained, and "thermal expansion rate warning" and sensor health diagnosis are added;
Disadvantages: The cabinet panel needs to be modified (the height of the 3500 rack increases by 0.78 inches)
