330500-07-CN Piezo-velocity Sensor Bently Nevada

330500-07-CN Bently Nevada Velomitor Piezo-velocity Sensor – Precision Vibration Monitoring for Critical Machinery

• Measurement Range & Sensitivity: The 330500-07-CN offers a velocity range of 1270 mm/s (50 in/s) peak. It features a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%. This accuracy ensures precise vibration detection.
• Frequency Response & Linearity: Frequency response spans 4.5 Hz to 5 kHz (270 cpm to 300 kcpm) ±3.0 dB. Amplitude linearity stays within ±2% up to 152 mm/s (6 in/s) peak. The mounted resonant frequency exceeds 12 kHz.
• Temperature & Environmental Limits: Operating temperature ranges from -55°C to 121°C (-67°F to 250°F). Temperature sensitivity varies from -14% to +7.5% typical. The sensor survives shocks up to 5,000 g peak.
• Electrical & Output Specifications: Output bias voltage sits at -12 ±3.0 VDC referenced to Pin A. Dynamic output impedance is less than 2400 Ω. Broadband noise floor measures only 0.004 mm/s (160 μin/s) rms nominal.
• Physical Characteristics: The sensor weighs 142 grams (5.0 oz) typical. Its diameter is 25.3 mm (0.995 in) and height 63.2 mm (2.49 in). Case material uses durable 316L stainless steel.
• Mounting & Connectivity: Mounting thread option -07 specifies 3/8-16 UNC. The connector is a 2-pin Mil-C-5015 hermetically-sealed type with 316L stainless steel shell. Maximum mounting torque is 32-46 kg cm (24-40 in-lb).
• Cable & Grounding: The sensor supports a maximum cable length of 305 meters (1,000 feet) with part number 02173006. The case is isolated from ground. Recommended cable length for high vibration is 208 ft (63m).
• Certifications & Compliance: The 330500-07-CN carries hazardous area approvals including Ex ia IIC T4 and AEx ia IIC T4. It meets FCC Part 15, EMC Directive 2014/30/EU, and RoHS 2011/65/EU. Maritime approvals include DNV rules for ships and offshore standards.

Frequently Asked Questions (FAQ)

• Q: Is the 330500-07-CN a brand new original sensor?
  A: Yes, absolutely. We supply only brand new, original Bently Nevada sensors directly from authorized sources. No refurbished or counterfeit units.
• Q: What is the typical lead time for this Velomitor sensor?
  A: We have the 330500-07-CN in stock now. Your order will ship within 5 business days via FedEx, UPS, or DHL. Most customers receive delivery within one week.
• Q: Can I use this sensor in a hazardous area with gas groups?
  A: Yes. The 330500 holds Ex ia IIC T4 and AEx ia IIC T4 approvals. It suits Class I, Division 1, Groups A, B, C, D and Class II, Groups E, F, G. Follow installation drawing 167537.
• Q: What happens if I exceed the operating temperature range?
  A: Operating outside -55°C to 121°C may cause false readings or loss of machine monitoring. The sensor's temperature sensitivity shifts -14% to +7.5% within the rated range.
• Q: How long of a cable can I use with this piezo-velocity sensor?
  A: You can run up to 305 meters (1000 feet) of cable part 02173006 without signal degradation. For high vibration (50g at 10 kHz), limit cable length to 63 meters due to capacitance.
• Q: Do you accept returns if the sensor does not fit my machine?
  A: Yes. We support 30-day returns for unused items in original condition. Contact our team first to arrange the return authorization.
