Parameter Analysis

The 330709-000-080-90-11-00 offers a total length of 9.0 meters, providing flexibility in routing from the probe tip to the proximitor. The probe DC resistance of 8.5 ± 1.1 ohms ensures consistent signal transmission. The recommended minimum target flat surface diameter is 30.5 mm (1.2 in), and minimum shaft diameter is 152 mm (6.0 in) to avoid cross-talk limitations. The probe case is made of AISI 304 stainless steel for durability, and the tip uses PPS for high-temperature resistance. The operating temperature range of -52°C to +177°C makes it suitable for harsh environments.

Application Scenarios

This proximity probe is widely used for vibration and position monitoring in rotating machinery such as turbines, compressors, pumps, and other critical equipment. It is commonly applied in industries like power generation, oil & gas, petrochemical, and manufacturing. The 3300 XL 11 mm probe is suitable for radial vibration, axial position, and speed measurements when paired with compatible Bently Nevada monitoring systems.

Installation Guide

Install the probe with the recommended torque of 21.1 N•m (187 in•lb) for the M16x1.5 case. Ensure the thread engagement does not exceed 24 mm. The connector should be finger tight, with a maximum torque of 0.565 N•m (5 in•lb). Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. For optimal performance, observe the recommended minimum target size and shaft diameter. Follow the manufacturer’s service manual for detailed installation instructions.

Compatibility

This probe is designed for use with Bently Nevada 3300 XL and 3500 monitoring systems. It is compatible with standard 3300 XL extension cables and proximitors. The ClickLoc connector ensures secure and reliable connection. The probe can be used with various target materials, but calibration may be required for non-ferromagnetic targets.

Maintenance Advice

Regularly inspect the probe and cable for damage or wear. Keep the probe tip clean and free from contaminants. Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal. Ensure all connections are tight and secure. Periodically verify the probe resistance to ensure it remains within specification.

Procurement Advice

When purchasing the Bently Nevada 330709-000-080-90-11-00, verify the model number and specifications to ensure it meets your application requirements. Consider the total length, thread type, and connector options. Purchase from authorized distributors or reputable suppliers to guarantee authenticity and warranty support. Check for any additional accessories needed, such as extension cables or mounting hardware.
