Bently Nevada 330851-04-000-015-10-05 3300XL 25mm Proximity Probe Side Exit

Product Overview
The Bently Nevada 330851-04-000-015-10-05 is a rugged, low-profile piezo-electric accelerometer engineered for continuous vibration surveillance on high-speed pumps, compressors, gearboxes and motors. Delivering a 100 mV/g sensitivity output with ultra-low noise floor, the sensor provides reliable early fault detection (bearing defects, gear wear, lubrication issues) across a wide frequency range, enabling predictive maintenance programs that maximize uptime and reduce lifecycle costs.

Key Specifications

• Frequency Response: 1 Hz – 10 kHz (±3 dB)
• Amplitude Range: ±50 g peak
• Supply Current: 2 – 10 mA constant-current drive, 18 – 30 V DC
• Operating Temperature: –55 °C to +125 °C (–67 °F to +257 °F)
• Case Material: 316 L stainless steel, hermetically sealed, IP68 rated
• Mounting Thread: M8 × 1 integral stud; supplied with M8-to-¼-28 UNF adapter
