Description

The 330909-00-20-10-02-05 is a high-precision 3300 NSv Proximity Probe engineered by Bently Nevada for non-contact vibration and displacement measurements in tight industrial spaces. As a specialized member of the 3300 NSv transducer family, this proximity probe is specifically designed for applications where standard probes cannot be installed due to restricted side-view clearances or small target diameters. This model features a 2.0-inch overall case length with a 0.0-inch unthreaded length, allowing for a flush-mount configuration that is ideal for compact bearing housings. The 330909-00-20-10-02-05 facilitates the monitoring of radial vibration and axial position by generating a linear voltage signal directly proportional to the gap between the probe tip and the target.

The 3300 NSv Proximity Probe is highly valued for its robust mechanical integrity and advanced material science. It utilizes patented TipLoc technology to create a permanent, high-strength bond between the probe tip and the stainless steel body, ensuring the sensor withstands intense thermal cycling and continuous vibration. Furthermore, the CableLoc design provides a 220 N (50 lb) pull strength, securing the 1.0-meter (39 in) standard cable against accidental tension during maintenance. This proximity probe is fully compatible with legacy 3300 RAM systems, offering a seamless upgrade path for plants looking to modernize their machinery protection infrastructure without costly mechanical redesigns.

Applications

The 330909-00-20-10-02-05 is primarily utilized in small-scale rotating equipment such as centrifugal compressors, high-speed pumps, and small steam turbines where mounting space is extremely limited. Its 0.0-inch unthreaded length and 2.0-inch case allow it to be installed in shallow bearing housings where a standard 8mm probe would be too long. The probe provides high-fidelity radial vibration data, allowing operators to detect shaft unbalance or misalignment early, even on shafts with small diameters that typically cause "side-view" interference for larger sensors.

In the petrochemical and gas processing industries, this 3300 NSv Proximity Probe serves as a vital tool for monitoring thrust position in environments exposed to aggressive industrial fluids and solvents. The enhanced chemical resistance of the probe tip and cable jacket ensures long-term reliability in "wet" bearing environments where oil and process gases are present. Because this model includes Multiple Approvals, it can be deployed directly in Zone 0 and Zone 1 hazardous areas, providing a certified safety link for critical machinery protection racks such as the Bently Nevada 3500 series.

Specifications

Competitive Advantage

Optimized for Small Targets and Restricted Clearances The 330909-00-20-10-02-05 features a "Narrow Surface" (NSv) design that allows it to outperform standard probes when measuring small targets (less than 13 mm in diameter) or when installed in locations with limited side-view clearance. This prevents the "signal interference" from surrounding metal that often plagues larger eddy-current sensors, ensuring a clean, linear output for high-precision displacement monitoring.

Patented Mechanical Robustness (TipLoc & CableLoc) Bently Nevada’s proprietary TipLoc molding process ensures that the probe tip remains permanently attached to the body, even under extreme mechanical stress. Additionally, the CableLoc retention system offers a superior pull strength of 220 N. These combined features drastically reduce the risk of probe failure due to vibration or maintenance-related handling, leading to lower total cost of ownership and higher system uptime.

Global Hazardous Area Compliance and Reliability With the Multiple Approvals (-05) option, this probe meets CSA, ATEX, and IECEx standards, making it globally ready for deployment in explosive atmospheres. Its exceptional supply sensitivity (less than 2 mV change per volt) ensures that the output signal remains stable despite the electrical noise and voltage fluctuations common in heavy industrial power grids, providing reliable data for critical safety shutdowns.
