Application Scenarios

This probe is widely used for monitoring vibration and axial position in rotating machinery such as turbines, compressors, pumps, and electric motors. It is also suitable for measuring shaft vibration, eccentricity, and thrust position in critical equipment. The 3300 XL 11 mm probe is ideal for applications requiring high accuracy and reliability, including in power generation, oil and gas, and petrochemical industries.

Installation Guide

Install the probe with the recommended torque: for M16x1.5 probe cases, the maximum rated torque is 63.3 N•m (560 in•lb), and the recommended torque is 21.1 N•m (187 in•lb). The connector-to-connector torque should be finger tight, with a maximum of 0.565 N•m (5 in•lb). Ensure the minimum bend radius of the cable is at least 25.4 mm (1.0 in). The maximum length of thread engagement is 24 mm. Follow the manufacturer’s instructions for proper gap setting and mounting.

Compatibility

This probe is compatible with Bently Nevada 3300 XL series monitoring systems, including the 3300/3500 racks and associated proximitors. It is designed to work with 3300 XL extension cables and is part of the 3300 XL family. The probe’s connector type (ClickLoc) ensures a secure connection with compatible extension cables.

Maintenance Advice

Regularly inspect the probe tip and cable for damage or wear. Keep the probe tip clean and free from debris. Ensure that the probe is not exposed to temperatures below -34°C (-30°F) to avoid premature failure of the pressure seal. Check the cable for any cuts or abrasions, and verify that all connections are tight. Periodically verify the probe’s DC resistance to ensure it remains within specification.

Procurement Advice

When purchasing the Bently Nevada 330709-000-230-10-11-00, ensure that the model number matches your system requirements. Verify the total length, thread type, and connector options. Consider purchasing from an authorized channel like TenBN to guarantee genuine parts and technical support. Also, check the agency approval options if required for your application.

FAQ

What is the operating temperature range of this probe?

The operating and storage temperature range is -52°C to +177°C (-62°F to +351°F). However, exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal.

What is the recommended minimum target size?

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

Is this probe compatible with 3500 series racks?

Yes, the 3300 XL probes are compatible with both 3300 and 3500 series monitoring systems when used with appropriate proximitors and extension cables.

What is the probe’s DC resistance?

For a 1.0 meter probe, the DC resistance from the center conductor to the outer conductor is 5.9 ± 0.5 ohms.

Can this probe be used with armored cable?

This specific model (330709-000-230-10-11-00) is without armor. If armor is required, please select a different model option.
