Description

The 330425-02-05 is a high-reliability accelerometer from the Bently Nevada 3300 series, specifically configured for critical machinery applications where casing acceleration measurement is essential. This variant features a 25 mV/g sensitivity and a 75 g peak amplitude range, making it suitable for monitoring gear mesh and other high-frequency vibration events. This unit utilizes an M8 x 1 integral mounting stud (Option 02) and is rated for operation in hazardous areas with multiple agency approvals (Option 05), including CSA, ATEX, and IECEx. Designed to operate in harsh industrial environments, the 330425-02-05 provides a robust solution for protecting rotating machinery. The sensor is constructed with a 316L stainless steel case, offering excellent resistance to corrosion and environmental degradation. It is fully compatible with existing 3300 series monitoring systems and is engineered for installation on bearing housings or machine casings to ensure accurate signal transmission for vibration analysis and protection.

Features

Sensitivity: 25 mV/g (2.5 mV/m/s2) with a 75 g peak acceleration range.
Mounting: Integrated M8 x 1 mounting stud (Option 02).
Approvals: Multiple hazardous area certifications including CSA, ATEX, and IECEx (Option 05).
Construction: 316L stainless steel, hermetically sealed casing for environmental protection.
Frequency Response: 10 Hz to 15 kHz (+/- 3 dB); 30 Hz to 10 kHz (+/- 10%).
Mounting Resonant Frequency: Greater than 30 kHz.
Operating Temperature: -55 degC to +121 degC (-67 degF to +250 degF).
Grounding: Case isolated for electrical interference reduction.

Applications

Gear mesh monitoring in rotating machinery
Bearing housing vibration measurement
Critical machinery protection for motors, pumps, and compressors
General purpose casing acceleration for high-frequency vibration analysis
Hazardous area machinery monitoring
