The 330400-01-00 is an industrial accelerometer designed for critical machinery casing acceleration measurements, such as gear mesh monitoring. This configuration features a 1/4-28 UNF integral mounting stud (Option 01) and no hazardous area agency approvals (Option 00), providing a standardized solution for non-hazardous monitoring environments. The transducer provides an amplitude range of 50 g peak and a sensitivity of 100 mv/g, adhering to the requirements of the American Petroleum Institute (API) Standard 670 for casing accelerometers.
Used primarily to detect malfunctions such as unbalance and misalignment, this accelerometer transmits rotor vibration signals to the bearing housing or machine casing. It is constructed from 316L stainless steel and features a 3-pin MIL-C-5015 receptacle for reliable connection to monitoring systems. The 330400 series is designed for environments where casing acceleration is a primary indicator of machinery health, ensuring compatibility with standard Bently Nevada vibration monitoring instrumentation.
