330500-05-02 | Bently Nevada Velomitor Sensor ATEX

Bently Nevada 330500-05-02 Velomitor Piezo-velocity Sensor – ATEX Approved

• Manufacturer & Model: Bently Nevada (Made in U.S.A). The 330500-05-02 features a hermetically sealed 2-pin Mil-C-5015 connector.
• Agency Approval Option -02: ATEX (European) certified. This sensor meets European hazardous area requirements.
• Electrical Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%. This value ensures precise velocity tracking across the full measurement range.
• Frequency Response: 4.5 Hz to 5 kHz (270 cpm to 300 kcpm) ±3.0 dB. Also 6.0 Hz to 2.5 kHz (360 cpm to 150 kcpm) ±0.9 dB for tighter tolerance.
• Velocity Range: 1270 mm/s (50 in/s) peak. The sensor handles high-amplitude vibrations without distortion or clipping.
• Amplitude Linearity: ±2% up to 152 mm/s (6 in/s) peak. This maintains measurement integrity under dynamic loads.
• Transverse Sensitivity: Less than 5% of sensitivity. It minimizes cross-axis errors for cleaner data output.
• Mounted Resonant Frequency: Greater than 12 kHz. This avoids structural resonance within the standard operating band.

Electrical & Output Specifications

• Output Bias Voltage: -12 ±3.0 VDC over temperature (referenced to Pin A). Stable bias supports consistent signal conditioning.
• Dynamic Output Impedance: Less than 2400 Ω. Low impedance drives long cable runs effectively.
• Broadband Noise Floor (4.5 Hz to 5 kHz): 0.004 mm/s (160 μin/s) rms nominal. Low noise floor captures small velocity changes.
• Grounding: Case isolated. This prevents ground loops and electromagnetic interference.
• Maximum Cable Length: 305 metres (1,000 feet) using cable part number 02173006 with no signal degradation.
• Recommended Cable Length (50g, 10 kHz, 200 pF/m): 208 ft (63m). Optimizes high-frequency performance.

Environmental & Physical Limits

• Operating Temperature Range: -55°C to 121°C (-67°F to 250°F). The 330500-05-02 works in extreme thermal conditions.
• Shock Survivability: 5,000 g peak maximum. Withstands severe mechanical shocks from machinery impacts.
• Relative Humidity: To 100% non-submerged (case is hermetically sealed). No moisture ingress risk.
• Base Strain Sensitivity: 0.005 in/s/mstrain. Minimizes errors from mounting surface deformation.
• Magnetic Field Susceptibility: <51 min/s/gauss (50 gauss, 50-60Hz). Resists EMI from motors and generators.
• Weight: 142 grams (5.0 oz) typical. Lightweight design reduces added mass on machinery.
• Diameter: 25.3 mm (0.995 in). Height: 63.2 mm (2.49 in). Compact form fits tight installations.
• Case Material: 316L stainless steel. Provides excellent corrosion resistance.
• Connector: 2-pin Mil-C-5015 hermetically sealed with 316L stainless steel shell. Ensures reliable electrical contact.
• Mounting Torque: 32-46 kg cm (24-40 in-lb) maximum. Follow this torque to avoid damage.
• Polarity: When the sensor case moves toward the connector, Pin A becomes positive with respect to Pin B. Easy wiring verification.

Frequently Asked Questions (FAQ)

• Q: Is the 330500-05-02 a genuine Bently Nevada sensor with ATEX?
  A: Yes, absolutely. We supply only brand new, original Bently Nevada sensors. This 330500 model includes full ATEX (European) certification.
• Q: What does the -02 agency approval mean?
  A: The -02 option provides ATEX (European) certification. It qualifies the sensor for use in European hazardous areas per ATEX directive.
• Q: What mounting thread does the -05 option require?
  A: The -05 option is unavailable for 330500. For 1/4-18 NPT mounting, please order 330525 instead.
• Q: What is the operating temperature range of this Velomitor sensor?
  A: The 330500-05-02 operates from -55°C to 121°C (-67°F to 250°F). It withstands extreme industrial environments.
• Q: Can I use this sensor in a hazardous area?
  A: Yes. It carries Ex ia IIC T4 and AEx ia IIC T4 approvals for Class I, Division 1, Groups A, B, C, D. Also suitable for Class II/III. T4 rating from -40°C to 100°C.
• Q: How long can the cable be without signal loss?
  A: Maximum cable length is 305 meters (1000 feet) using part number 02173006. For high vibration 50g at 10 kHz, limit to 63 meters (208 ft).
• Q: Do you have this sensor in stock?
  A: Yes, we keep the 330500-05-02 in stock. We ship within 5 days via FedEx, UPS, or DHL.
• Q: What is the sensitivity of the sensor?
  A: Sensitivity is 3.94 mV/mm/s (100 mV/in/s) ±5%. It provides a standard 100 mV/in/s output for velocity monitoring.
• Q: Is the case electrically isolated?
  A: Yes, the case is isolated. This prevents ground loops and improves signal integrity.
• Q: What happens if I exceed the velocity range?
  A: The sensor measures up to 1270 mm/s (50 in/s) peak. Exceeding this may cause non-linear output or damage.
