Bently Nevada 330400-02-05 Accelerometer

Description

The 330400-02-05 is a high-precision acceleration transducer designed for critical machinery monitoring applications, such as gear mesh analysis and casing vibration measurement. This configuration features an M8 x 1 integral mounting stud (Option 02) and includes multiple agency approvals (Option 05), including CSA, ATEX, and IECEx certifications for use in hazardous environments.

Engineered to meet the requirements of the American Petroleum Institute (API) Standard 670, this accelerometer delivers a sensitivity of 100 mV/g with an amplitude range of 50 g peak. The 330400 series provides consistent performance in demanding industrial settings, with a wide frequency response range of 10 Hz to 15 kHz. Its hermetically sealed, 316L stainless steel case ensures reliability in harsh, condensing, and non-submerged environments.
