The 330400-01-05 (330400) is a high-precision piezoelectric accelerometer engineered specifically for critical machinery protection and condition monitoring. As a core component of the Bently Nevada vibration monitoring suite, this sensor is designed to meet the rigorous American Petroleum Institute (API) Standard 670 requirements. It delivers a linear output of 100 mV/g, making it ideal for detecting high-frequency vibration characteristics in rotating equipment such as gas turbines, compressors, and pumps.
This transducer offers an expansive frequency response range from 10 Hz to 15 kHz, ensuring comprehensive coverage of mechanical health indicators. The 330400-01-05 maintains exceptional amplitude linearity of ±1% up to a 50 g peak range. With a mounted resonant frequency exceeding 30 kHz, the sensor minimizes signal distortion at high speeds, while the case-isolated design prevents ground loop interference in complex industrial electrical environments.
Encapsulated in a hermetically sealed 316L stainless steel housing, the 330400-01-05 is built for extreme reliability. It features an IP68 equivalent rating, providing total protection against dust and moisture ingress. The unit operates reliably in temperatures ranging from -55°C to +121°C, making it suitable for both cryogenic and high-heat industrial processes. This specific configuration includes a 1/4-28 UNF integral mounting stud and carries comprehensive global hazardous area certifications (CSA, ATEX, IECEx).
