Bently Nevada 330400-02-00 Accelerometer

Description

The 330400-02-00 is an industrial acceleration transducer designed for critical machinery monitoring applications, providing a reliable 100 mV/g sensitivity and a 50 g peak amplitude range. This specific configuration features an M8 x 1 integral mounting stud (Option 02) and is supplied without hazardous area agency approvals (Option 00). It serves as a core component in vibration monitoring systems, essential for detecting gear mesh issues, unbalance, and misalignment in rotating machinery. Engineered to meet American Petroleum Institute (API) Standard 670 requirements for accelerometers, this unit delivers high-performance casing acceleration measurements. The transducer operates effectively in a wide temperature range of -55 Celsius to +121 Celsius and features a robust, hermetically sealed 316L stainless steel housing equivalent to IP68 rating, ensuring protection in harsh industrial environments.

Installation Guidelines

Ensure the accelerometer is installed on a flat, clean bearing housing or machine casing surface. Proper mounting is critical to avoid false signals; a surface finish of 32 micro-inch rms or better is recommended. Torque the unit to 4.1 N-m during installation. The unit is case-isolated and should be connected via shielded cabling to prevent electromagnetic interference. Standard practice includes installing the sensor in a protected enclosure with wiring routed through conduit.
