Parameter Analysis

The 330709-000-080-10-12-05 offers a low DC resistance of 5.9 ohms, ensuring minimal signal loss. The PPS tip provides excellent dielectric properties and durability. The stainless steel case ensures corrosion resistance. The M16 x 1.5 thread allows secure mounting, with a recommended torque of 21.1 N•m to avoid over-tightening. The probe’s temperature range of -52°C to +177°C makes it suitable for harsh environments. The minimum target size and shaft diameter guidelines ensure accurate readings without cross-talk.

Application Scenarios

This proximity probe is ideal for vibration and position monitoring on turbines, compressors, pumps, and other rotating machinery. It is commonly used in applications such as radial vibration measurement, axial position monitoring, and speed/phase reference. The 330709-000-080-10-12-05 is compatible with Bently Nevada 3300 and 3500 monitoring systems, providing reliable data for predictive maintenance and machine protection.

Installation Guide

1. Ensure the mounting surface is clean and the thread is properly prepared.
2. Screw the probe into the mounting hole using the recommended torque of 21.1 N•m (187 in•lb). Do not exceed 63.3 N•m (560 in•lb).
3. Route the cable with a minimum bend radius of 25.4 mm to avoid damage.
4. Connect the ClickLoc connector to the extension cable, tightening finger tight (max 0.565 N•m).
5. Verify the probe gap according to the system calibration requirements.

Compatibility

The 330709-000-080-10-12-05 is part of the 3300 XL series and is compatible with Bently Nevada 3300 and 3500 monitoring systems. It uses a miniature coaxial ClickLoc connector and FluidLoc cable, which are standard for these systems. The probe is designed for use with 5 mm and 8 mm extension cables and is approved for hazardous areas with multiple certifications.

Maintenance Advice

Regularly inspect the probe and cable for physical damage. Keep the probe tip clean and free from debris. Check the connector tightness periodically. Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal. Ensure the cable bend radius is maintained during installation and operation.

Procurement Advice

When ordering, verify the model number 330709-000-080-10-12-05 to ensure it matches your requirements. Confirm the thread size, cable length, and connector type. Consider purchasing from authorized Bently Nevada distributors to guarantee genuine parts and warranty support. For large orders, inquire about bulk pricing and lead times.

FAQ

Q1: What is the difference between the 330709 and other 3300 XL probes?
A1: The 330709 is a specific configuration with M16 x 1.5 thread, 80 mm case length, and 1.0 m cable. Other models may have different thread sizes or lengths.

Q2: Can this probe be used in hazardous areas?
A2: Yes, the 330709-000-080-10-12-05 has multiple approvals (option 05) and is suitable for hazardous locations with appropriate temperature classifications.

Q3: What is the maximum cable length available?
A3: The 3300 XL probes are available in 1, 5, or 9 meter total lengths. This model has a 1.0 meter cable.

Q4: How do I ensure proper installation torque?
A4: Use a torque wrench set to 21.1 N•m (187 in•lb) for the probe case. For the connector, tighten finger tight only.

Q5: Is the probe tip replaceable?
A5: No, the probe tip is integral to the probe. If damaged, the entire probe must be replaced.
