Comparison with similar models and alternatives

Model

Advantages

Disadvantages

Bently Nevada 3300/45

Dedicated differential expansion (DE) algorithm; Supports dual-slope/complementary measurement modes

Limited to DE function; No vibration/temperature channels

3300/16 (Vibration Monitor)

Multi-parameter integration (vibration + Keyphasor®)

Requires external signal conditioner for DE monitoring

Alternative: 3500/45

Channel capacity increased to 4; Integrated System 1® diagnostics

Requires 3500 rack replacement; Upgrade cost increases by 60%

Alternative: 3701 ADAPT

Distributed architecture; Supports wireless transmission

Only supports vib/tach; Incompatible with DE monitoring

Upgrade suggestion:

The 3300 series has been discontinued, the Bently Nevada 3300/45 is a direct replacement for the 3500/45:

Advantages: Compatible with the original 50 mm probe, with the new "thermal expansion rate warning" function;

Disadvantages: The rack and backplane need to be upgraded simultaneously, and the transformation period is 3-4 weeks.
