Parameter Analysis

The 330709-000-080-10-11-05 probe offers a DC resistance of 5.9 ± 0.5 ohms, ensuring consistent performance. 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 is PPS for chemical resistance. The operating temperature range of -52°C to +177°C makes it suitable for harsh environments, though exposure below -34°C may affect the pressure seal.

Application Scenarios

This proximity probe is ideal for monitoring vibration and position in critical rotating machinery such as turbines, compressors, pumps, and other industrial equipment. It is commonly used in applications requiring precise shaft radial vibration and axial position measurements to prevent machinery damage and optimize maintenance schedules.

Installation Guide

Install the probe using the M16 x 1.5 thread with a recommended torque of 21.1 N•m (187 in•lb) and maximum torque of 63.3 N•m (560 in•lb). The maximum thread engagement length is 24 mm. Ensure the target surface meets the minimum size requirements. 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 for the cable to prevent damage.

Compatibility

The 330709-000-080-10-11-05 is part of the 3300 XL series and is compatible with Bently Nevada 3300/3500 monitoring systems. It works with standard 3300 XL extension cables and proximitors. The probe is designed for use with 75 ohm triaxial cables and is available in lengths of 1, 5, or 9 meters.

Maintenance Advice

Regularly inspect the probe tip and cable for damage. Ensure the probe is kept clean and free from contaminants. Avoid exposing the probe to temperatures below -34°C to prevent premature failure of the pressure seal. Check connector tightness periodically, but do not over-torque.

Procurement Advice

When ordering the Bently Nevada 330709-000-080-10-11-05, verify the model number to ensure it matches your requirements for thread size, length, and connector type. Confirm the total length (1.0 meter) and cable type (FluidLoc) are suitable for your installation. Consider purchasing from authorized distributors to guarantee genuine parts and warranty support.
