Product Introduction
The Bently Nevada 330905-00-10-10-02-05 is a 3300 XL Side‑Exit Accelerometer (piezoelectric, IEPE type) designed for measuring absolute casing vibration on rotating machinery. Unlike proximity probes which measure shaft‑relative motion, this accelerometer mounts directly on bearing housings or machine casings to detect bearing wear, imbalance, misalignment, and gear mesh faults. The “side‑exit” (right‑angle) cable orientation allows installation in tight spaces where top‑exit accelerometers cannot fit. The -05 suffix indicates hazardous area approvals (ATEX, CSA, IECEx Zone 0/1/2, gas and dust). The integral cable length is 1.0 meter (suffix -10), terminated with a miniature coaxial connector (option -02) for direct connection to 3500/42M or 3500/60 monitors, or to junction boxes.
The part number breaks down as:
330905 – 3300 XL Side‑Exit Accelerometer (100 mV/g sensitivity)
00 – Standard mounting thread (1/4‑28 UNF)
10 – Integral cable length: 1.0 m (39.4 in)
10 – Cable termination: Miniature coaxial male (Mini‑Type)
02 – Optional configuration (e.g., filtered output or special response)
05 – Hazardous area approvals (ATEX, CSA, IECEx Zone 0/1/2)
The accelerometer is constructed from stainless steel with a hermetically sealed housing, making it suitable for harsh industrial environments.

Application Scenarios
Bearing Housing Vibration Monitoring – Mounted directly on rolling element bearing housings of motors, pumps, fans, and compressors to detect early bearing faults, imbalance, and looseness in hazardous areas (refineries, chemical plants, offshore platforms). The -05 approval permits installation in Zone 0/1/2 explosive atmospheres.
Gearbox and Casing Vibration – Used on gearboxes, small steam turbines, and gas turbine casings where absolute vibration measurement is required. The side‑exit design allows mounting in narrow clearances between flanges or adjacent components.
Integration with 3500 Series Monitors – The 4‑20 mA output (via a 3500/60 or 3500/42 monitor with accelerometer input) provides continuous protection data to the 3500 rack, enabling programmable Alert/Danger alarms and shutdown logic.
Condition Monitoring in Petrochemical Plants – Installed on critical pumps, blowers, and reciprocating compressors to provide real‑time casing vibration trends, supporting predictive maintenance and reducing unplanned downtime.
Hard‑to‑Access Locations – The side‑exit cable orientation and compact stainless steel housing (22 × 22 mm footprint) allow installation in tight spaces, such as between motor windings, inside bearing cover bolts, or on small auxiliary machinery where standard top‑exit accelerometers would interfere with adjacent hardware.
Replacement of Legacy Accelerometers – Directly replaces older Bently Nevada 3300 or 7200 series accelerometers (e.g., 330700 series) while providing improved temperature range, hazardous area certification, and compatibility with modern 3500 rack inputs.
