• Probe Weight: Approximately 14 to 150 grams (0.5 to 5.3 oz), depending on length.

Construction & Materials

• Probe Case: Manufactured from corrosion-resistant AISI 304 stainless steel.
• Probe Tip: Precision-molded from rugged Polyphenylene sulfide (PPS) plastic.
• Cable Insulation: High-quality FEP insulation ensures stable electrical performance.
• Pressure Seal: Designed with a Viton® O-ring to seal differential pressure.
• Connector: Reliable Miniature Coaxial ClickLoc connector for a secure system connection.
• Length Options: Available in 0.5, 1, 5, or 7-meter total probe lengths to suit various applications.

Environmental Ratings & Limits

• Operating Temperature: Rated for -52°C to +177°C (-62°F to +351°F).
• Storage Temperature: Can be stored within the same -52°C to +177°C range.
• Low-Temperature Caution: Sustained exposure below -34°C (-30°F) may damage the pressure seal.
• Pressure Testing: Probes are not pressure tested before shipment as a standard procedure.
• Agency Approvals: Carries multiple international approvals for use in regulated industries.

Installation & Application Notes

• Long-Reach Use: The 7-meter length is ideal for applications where the monitor is far from the measurement point.
• Torque Guidance: Always use a torque wrench. Do not exceed the recommended 11.3 N•m to avoid case damage.
• Thread Care: Ensure threads are clean and engage smoothly. Do not force the probe beyond its engagement limit.
• System Integration: Compatible with 3300 NSv compatible monitors and signal conditioners.
• Cable Handling: Route the long cable carefully to avoid sharp bends, kinks, or excessive tension.

Frequently Asked Questions (FAQ)

What is the 3300 NSv series, and how does it differ from the 3300 XL?

• The 3300 NSv is a distinct product line from Bently Nevada. It often features different electrical characteristics (like 75 Ω cable) and may be optimized for specific system integrations or cost-effective solutions compared to the 3300 XL series.

Why is the recommended installation torque important?

• Applying the correct 11.3 N•m (100 in•lb) torque ensures a secure fit without stripping the stainless steel threads or damaging the probe case, guaranteeing a reliable mechanical installation.

Can I cut or shorten the 7-meter cable if my application is shorter?

• No. The probe cable is a calibrated part of the system. Cutting it will change the electrical characteristics (resistance, capacitance) and make the probe inaccurate. Always order the correct length.

What does FEP cable insulation offer?

• FEP (Fluorinated Ethylene Propylene) insulation provides excellent chemical resistance, high-temperature stability, and low signal loss. This makes it suitable for demanding industrial environments.

Is this probe suitable for hazardous areas?

• Yes. The agency approval option '05' indicates the probe is certified for use in hazardous locations. It carries CSA, ATEX, and IECEx approvals, but always verify the specific certification matches your area classification.
