The 330400-01-00 is a high-precision accelerometer manufactured by Bentley Nevada, Inc. This sensor is commonly used for condition monitoring of industrial equipment, particularly suitable for measuring the vibration of rotating machinery housings, and is widely used in industries such as power generation, steel, metallurgy, and petrochemicals.
Superior Signal-to-Noise Ratio
Compliant with API 670 requirements
High Sensitivity for High-Frequency Detection
These accelerometers are intended for critical machinery applications where casing acceleration measurements are required, such as gear mesh monitoring. The 330400 complies with 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.As an industrial benchmark compliant with API 670 standards, the 330400-01-00 not only accurately captures vibration amplitudes up to 50 g peak, but its high sensitivity of 100 mV/g also makes it the ideal choice for monitoring gear mesh frequencies and early-stage bearing defects. Leveraging an exceptional signal-to-noise ratio, this sensor effectively extracts faint, high-frequency impact signals from complex background mechanical noise, providing reliable predictive maintenance for critical rotating machinery.

Steel Rolling
Monitoring cold/hot rolling mill gearboxes. It provides early warning of tooth breakage risks for heavy-duty, low-speed gear sets with high-frequency meshing characteristics.
Petrochemical Refining
Monitoring high-speed gear increasers in centrifugal compressors. The accelerometer captures micro high-frequency impacts caused by gear tooth wear or pitting.
Pulp & Paper
Monitoring support bearings in the dryer section. It detects bearing housing cracks or rolling element failures caused by long-term high-temperature operation.
Offshore Engineering
Monitoring gear drives in top drive systems on drilling rigs. It provides reliable high-frequency fault diagnosis in salt spray and high-humidity environments.
Semiconductor
Monitoring large cleanroom centrifugal pumps. Through acceleration measurement, it ensures no abnormal vibration in cooling systems to avoid disturbing precision lithography equipment.
When using the 330400-01-00 accelerometer, ensure the sensor is rigidly mounted to a flat metal surface using the recommended torque to guarantee accurate high-frequency signal transmission. Meanwhile, protect the cable with conduit and keep connectors dry and clean to prevent signal drift caused by moisture ingress, while strictly following mounting clearance and wiring specifications to minimize electromagnetic interference.
