Description
These accelerometers are intended for critical machinery applications where casing acceleration measurements are required, such as gear mesh monitoring. The 330400 is designed to address the requirements of American Petroleum Institute Standard 670 for accelerometers. It provides an amplitude range of 50 g peak and a sensitivity of 100 mV/g. The 330425 is identical except it provides a larger amplitude range (75 g peak) and a sensitivity of 25 mV/g.
Feature
High Sensitivity (25 mV/g): This model offers a sensitivity of 25 mV/g (2.5 mV/m/s²). This lower sensitivity compared to some other models (like the 330400 which is 100 mV/g) allows it to measure a larger amplitude range. Wide Acceleration Range (75 g peak): It can reliably measure peak overall acceleration up to 735 m/s² (75 g) within its specified frequency span. This wide range is particularly beneficial for detecting severe vibration events. Broad Frequency Response: The accelerometer provides a wide frequency response from 10 Hz to 15 kHz (600 cpm to 900,000 cpm) with a ±3dB accuracy, and 30 Hz to 10 kHz (1800 cpm to 600,000 cpm) with ±10% accuracy.
