Quick Detail

Description

The 330400-01-CN Accelerometer is a high-precision vibration sensor designed for critical industrial machinery monitoring and automation applications. Engineered to measure casing accelerations with exceptional accuracy, it features a ¼-28 UNF integral stud mounting for secure installation and is fully certified under CSA, ATEX, and IECEx standards, enabling safe deployment in hazardous environments. This accelerometer delivers a sensitivity of 10.2 mV/m/s² (100 mV/g) ±5% and an acceleration range of 490 m/s² (50 g) peak, covering a wide frequency spectrum from 10 Hz to 15 kHz. Its broadband noise floor of 0.039 m/s² (0.004 g) rms and amplitude linearity of ±1% to 50 g peak ensure precise vibration detection, while transverse sensitivity remains below 5% of axial, minimizing measurement errors. The 330400-01-CN is ideal for gear mesh monitoring, rotor and shaft vibration analysis, and predictive maintenance, providing reliable real-time data for automation control systems. Its isolated grounded case design, low temperature sensitivity (-11% to +3%), and high resonant frequency (>30 kHz) make it robust for extreme industrial conditions.

Applications

Gear Mesh Monitoring
The 330400-01-CN accelerometer enables precise detection of vibration from gear teeth contact, ensuring early identification of misalignment or wear. Its amplitude range of 50 g peak captures subtle casing movements in high-speed gear assemblies.

Rotor and Shaft Vibration Analysis
Used in rotating machinery such as turbines, pumps, and compressors, this accelerometer provides accurate shaft vibration measurements up to 15 kHz, supporting predictive maintenance and operational efficiency.

Critical Machinery Protection
Installed on critical assets, the sensor monitors acceleration to prevent catastrophic failure. The low broadband noise floor of 0.039 m/s² ensures early detection of abnormal vibration patterns.

Predictive Maintenance and Condition Monitoring
By providing real-time acceleration data with ±1% amplitude linearity, the 330400-01-CN supports automated maintenance scheduling and reduces unplanned downtime in industrial automation systems.

Hazardous Environment Operations
The accelerometer’s multiple approvals (CSA, ATEX, IECEx) and isolated grounding allow reliable use in explosive or high-risk environments such as petrochemical plants, offshore platforms, and refineries.
