• Minimum bend radius: 25.4 mm (1.0 inch) with or without SST armor.
• Operating temperature: -52°C to +177°C (-62°F to +351°F).
• Storage temperature: -52°C to +177°C (-62°F to +351°F).
• Probe pressure design: Seals differential pressure via Viton O-ring (not pressure tested before shipment).
• Connector-to-connector torque (M8x1 case): max rated 7.3 N•m (65 in•lb), recommended 5.1 N•m (45 in•lb).
• Maximum thread engagement length (M8x1): 12 mm.

Installation & Mounting Guidelines

• Torque application: Use finger tight for initial installation; never exceed 0.56 N•m on the probe body.
• Thread engagement: Ensure at least 12 mm of M8x1 thread engagement for secure mounting.
• Bending cable: Maintain a minimum bend radius of 25.4 mm to avoid damaging the coaxial cable.
• Gap setting procedure: Set the probe gap to 1.0 mm (40 mils) from the target for optimal linear operation.
• Field wiring recommendations: Use a three-conductor shielded triad cable (16–24 AWG). Keep total field wiring within 305 meters to preserve frequency response.
• Target considerations: For shaft diameters under 13 mm, reduce the gap to minimize scale factor changes. Refer to Figure 12 in the full manual.

Frequently Asked Questions (FAQ)

• Q: Is the 330903-00-03-10-11-00 brand new and original?
  A: Yes, every probe we offer is 100% new, original Bently Nevada stock in factory packing. No refurbished or counterfeit units.
• Q: Do you have this 3300 NSv probe in stock?
  A: We maintain real inventory. The 330903-00-03-10-11-00 is currently in stock and available for immediate order.
• Q: What is the linear range and recommended gap for this probe?
  A: The linear range spans 1.5 mm (from 0.25 mm to 1.75 mm). Bently Nevada recommends a 1.0 mm gap setting for standard applications.
• Q: What maximum temperature can this NSv probe withstand?
  A: The probe operates reliably from -52°C up to +177°C (-62°F to +351°F), both in operation and storage.
• Q: How long does shipping take and which carriers do you use?
  A: We dispatch within 5 business days. Ship via FedEx, UPS, or DHL. Transit times depend on your location (typically 2-6 days).
• Q: Can I return the product if it doesn’t fit my application?
  A: Yes, we offer a 30-day return policy from the delivery date. The probe must remain in original, unopened factory packaging.
• Q: What is the scale factor of the 330903-00-03-10-11-00?
  A: The incremental scale factor equals 7.87 V/mm (200 mV/mil) with +12.5%/-20% interchangeability tolerance.
• Q: Does the probe seal high pressure?
  A: The Viton O-ring seals differential pressure between tip and case. However, Bently Nevada does not pre-pressure-test each unit. Contact custom design for specific pressure tests.
