Parameter Analysis

The 330709-000-080-10-12-00 probe offers a low DC resistance of 5.9 ohms, ensuring minimal signal loss. The PPS tip provides excellent durability and chemical resistance. The stainless steel case ensures corrosion resistance in harsh environments. The 1.0 meter cable length is suitable for installations where the probe is close to the extension cable. The temperature range of -52°C to +177°C allows operation in extreme conditions, though exposure below -34°C may affect the pressure seal.

Application Scenarios

This probe is ideal for monitoring vibration and shaft position in critical rotating machinery such as turbines, compressors, pumps, and motors. It is commonly used in power generation, oil & gas, petrochemical, and other industrial plants where reliable condition monitoring is essential.

Installation Guide

Install the probe with the recommended torque of 21.1 N•m for the M16x1.5 case. Ensure the target surface is clean and meets the minimum diameter requirements. Use the ClickLoc connector for secure attachment to the extension cable. Avoid bending the cable beyond the minimum bend radius of 25.4 mm. For optimal performance, follow the manufacturer’s installation guidelines.

Compatibility

The 330709-000-080-10-12-00 is compatible with Bently Nevada 3300 XL system components, including extension cables and proximitors. It is designed to work with 3300 series monitors and other compatible systems.

Maintenance Advice

Regularly inspect the probe and cable for damage or wear. Keep the probe tip clean and free from contaminants. Check connector tightness periodically. Avoid exposing the probe to temperatures below -34°C to prevent premature failure of the pressure seal.

Procurement Advice

When ordering, verify the model number 330709-000-080-10-12-00 to ensure you receive the correct configuration. Confirm the total length, connector type, and agency approval options. Purchase from authorized distributors to guarantee genuine Bently Nevada quality.
