330500-06-CN Bently Nevada Velomitor Piezo-velocity Sensor

Bently Nevada 330500-06-CN Velomitor Piezo-velocity Sensor

• The 330500 series provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%. This accuracy ensures you track real machine vibration levels correctly.
• Frequency response spans 4.5 Hz to 5 kHz (270 to 300 kcpm) within ±3.0 dB. A tighter range of 6.0 Hz to 2.5 kHz gives you ±0.9 dB for critical assets.
• Velocity range reaches 1270 mm/s (50 in/s) peak. Amplitude linearity stays within ±2% up to 152 mm/s (6 in/s) peak for consistent readings.
• Output bias voltage measures -12 ±3.0 VDC referenced to Pin A. Dynamic output impedance sits below 2400 Ω to drive long cable runs.
• Broadband noise floor rests at 0.004 mm/s (160 μin/s) rms nominal from 4.5 Hz to 5 kHz. This low noise floor allows clear signal detection even on small vibrations.

Environmental and Physical Specifications

• Operating temperature range covers -55°C to 121°C (-67°F to 250°F). Relative humidity tolerance reaches 100% non-submerged thanks to hermetic sealing.
• Case material uses 316L stainless steel. The connector is a 2-pin Mil-C-5015 type with a 316L stainless steel shell for maximum durability.
• Weight typically equals 142 grams (5.0 oz). Diameter is 25.3 mm (0.995 in) and height is 63.2 mm (2.49 in).
• Mounting torque range measures 32-46 kg cm (24-40 in-lb) max. Polarity: when the case moves toward the connector, Pin A becomes positive relative to Pin B.
• Case is isolated from ground to prevent ground loops. Maximum cable length reaches 305 meters (1,000 feet) with part number 02173006 cable.
• Transverse sensitivity stays below 5% of main sensitivity. Magnetic field susceptibility is less than 51 min/s/gauss at 50–60 Hz.
