The Bently Nevada 330400 / 330425 Accelerometer 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.
