Functional Description
The 330400-01-00 accelerometer is engineered for casing vibration monitoring, particularly in gear mesh analysis and other applications requiring high sensitivity. It captures rotor-induced vibration through machine casings, enabling accurate detection of unbalance, misalignment, and bearing wear. Compared to the 330425 model (75 g peak range), the 330400-01-00 prioritizes higher sensitivity for subtle vibration changes.
Its rugged design ensures reliable performance in harsh industrial environments, while advanced shielding minimizes false signals. When paired with proximity probes (e.g., 3300XL series), it provides comprehensive monitoring of both casing and rotor dynamics, enhancing machinery protection strategies.
Application Scenarios
Gear mesh analysis in compressors and turbines
Bearing housing vibration monitoring
Pumps and motors in manufacturing operations
Low- to medium-speed rotating equipment requiring high sensitivity
