Parameter Analysis

The 330709-000-080-90-02-00 probe length of 9.0 meters ensures flexible installation while maintaining signal integrity. The DC resistance specification (8.5 ± 1.1 ohms) is critical for verifying cable and probe health. The probe tip material (PPS) offers excellent chemical resistance and thermal stability, while the stainless steel case provides durability in harsh environments. The M16 x 1.5 thread allows secure mounting, and the ClickLoc connector simplifies installation and removal.

Application Scenarios

This proximity probe is ideal for monitoring vibration and axial position in rotating machinery, including turbines, compressors, pumps, and other critical equipment. It is commonly used in conjunction with Bently Nevada 3300 XL monitoring systems to provide real-time data for predictive maintenance and protection.

Installation Guide

• Ensure the mounting surface is clean and free of debris.
• Thread the probe into the mounting hole using the recommended torque of 21.1 N•m (187 in•lb). Do not exceed maximum rated torque of 63.3 N•m (560 in•lb).
• Connect the ClickLoc connector to the extension cable, tightening finger tight (max 0.565 N•m / 5 in•lb).
• Route the cable with a minimum bend radius of 25.4 mm (1.0 in) to avoid damage.
• Verify the probe gap according to the system calibration requirements.

Compatibility

The 330709-000-080-90-02-00 is designed for use with Bently Nevada 3300 XL series monitors and proximity systems. It is compatible with standard 3300 XL extension cables and proximitors. For detailed system integration, refer to the service manual.

Maintenance Advice

• Periodically check the probe tip for buildup or damage.
• Inspect cable and connector for wear or corrosion.
• Verify DC resistance (RPROBE) to ensure within 8.5 ± 1.1 ohms.
• Keep the probe and cable away from excessive heat or chemicals that may degrade materials.

Procurement Advice

When ordering the Bently Nevada 330709-000-080-90-02-00, confirm the total length (9.0 m) and connector type (ClickLoc) match your system requirements. Verify agency approval needs; this model has ‘Not Required’. For large quantities, contact TenBN for volume pricing and lead times.

FAQ

Q1: What is the temperature range for this probe?

The operating and storage temperature range is -52°C to +177°C (-62°F to +351°F). Note that exposure below -34°C (30°F) may cause premature failure of the pressure seal.

Q2: What is the recommended mounting torque?

The recommended torque for the M16 x 1.5 probe case is 21.1 N•m (187 in•lb). The maximum rated torque is 63.3 N•m (560 in•lb).

Q3: Can this probe be used with armored cable?

This model (330709-000-080-90-02-00) is specified without armor. For armored versions, please consult the Bently Nevada 3300 XL series options.

Q4: What is the minimum target size?

For flat surfaces, the recommended minimum target diameter is 30.5 mm (1.2 in). For shafts, the recommended minimum diameter is 152 mm (6.0 in).

Q5: What is the probe DC resistance?

The DC resistance from the center conductor to the outer conductor is 8.5 ± 1.1 ohms for the 9.0-meter probe length.
