330500-01-02 Velomitor Piezo-velocity Sensor - Bently Nevada

Bently Nevada 330500-01-02 Velomitor Piezo-velocity Sensor: Precision Vibration Monitoring

Key Technical Specifications of the 330500 Velomitor Sensor

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) with ±5% accuracy. This rating applies at +20°C to +30°C and 100 Hz.
• Frequency Response: 4.5 Hz to 5 kHz (270 cpm to 300 kcpm) at ±3.0 dB. For tighter tolerance, 6.0 Hz to 2.5 kHz delivers ±0.9 dB.
• Velocity Range: 1270 mm/s (50 in/s) peak. This high range captures severe vibration events.
• Amplitude Linearity: ±2% up to 152 mm/s (6 in/s) peak. The sensor maintains accuracy across its operating range.
• Output Bias Voltage: -12 ±3.0 VDC referenced to Pin A. This bias remains stable over temperature changes.
• Dynamic Output Impedance: Less than 2400 Ω. This low impedance allows long cable runs without signal loss.
• Broadband Noise Floor (4.5 Hz to 5 kHz): 0.004 mm/s (160 μin/s) rms nominal. The noise floor ensures clean data for analysis.
• Mounted Resonant Frequency: Greater than 12 kHz. This high resonance avoids interference with measurement frequencies.
• Temperature Sensitivity: -14% to +7.5% typical over the operating temperature range.
• Transverse Sensitivity: Less than 5% of sensitivity. This low value minimizes cross-axis errors.

Environmental and Physical Durability

• Operating Temperature: -55°C to 121°C (-67°F to 250°F). The sensor performs reliably in extreme thermal conditions.
• Shock Survivability: 5,000 g peak maximum. This ruggedness protects the sensor during sudden impacts.
• Relative Humidity: Up to 100% non-submerged. The hermetically-sealed case prevents moisture ingress.
• Base Strain Sensitivity: 0.005 in/s/mstrain. Minimal strain response avoids false vibration readings.
• Magnetic Field Susceptibility: Less than 51 min/s/gauss (50 gauss, 50-60Hz). Strong magnetic fields do not disrupt measurements.
• Weight: 142 grams (5.0 oz) typical. The compact design simplifies installation on rotating machinery.
• Diameter and Height: 25.3 mm (0.995 in) diameter, 63.2 mm (2.49 in) height. These dimensions fit tight mounting spaces.
• Case Material: 316L stainless steel. This material resists corrosion in industrial and marine environments.

Installation and Mounting Guidelines for Model 330500

• Mounting Thread Option: -01 1/2-20 UNF. Use this thread for secure attachment to machine surfaces.
• Mounting Torque: 32-46 kg cm (24-40 in-lb) maximum. Do not exceed this torque to avoid damage.
• Connector Type: 2-pin Mil-C-5015 hermetically-sealed with 316L stainless steel shell. This connector ensures reliable signal transfer.
• Polarity Information: When the case moves toward the connector, Pin A becomes positive relative to Pin B. Follow this polarity for correct signal orientation.
• Maximum Cable Length: 305 meters (1,000 feet) using part number 02173006. This length does not degrade the signal.
• Recommended Cable Length: 208 ft (63m) for 50g vibration at 10 kHz with 200 pf/m cable capacitance. This recommendation optimizes performance.
• Grounding: Case isolated. This isolation prevents ground loops in monitoring systems.

Frequently Asked Questions (FAQ)

• Do you have the 330500-01-02 in stock?
  Yes, we have this model in stock. We maintain inventory for immediate shipment.
• What is the typical lead time for shipping?
  We ship within 5 days after order confirmation. Most orders leave our warehouse within 48 hours.
• Which carriers do you use for delivery?
  We ship via FedEx, UPS, and DHL. You can choose your preferred option at checkout.
• What is your return policy?
  We support returns within 30 days from delivery. The sensor must be unused and in original packaging.
• Can I use this sensor with a cable longer than 305 meters?
  The maximum recommended cable length is 305 meters (1000 feet) of part number 02173006. Longer runs may degrade signal quality.
