Description
The 330101-33-53-10-02-05 3300 XL 8 mm Proximity Probe is a high-precision sensing device designed for demanding industrial automation and machinery protection systems. As a core component of the 3300 XL 8 mm Proximity Probe family, this model delivers a stable output voltage that remains directly proportional to the gap between the probe tip and the monitored conductive target. This characteristic enables accurate detection of both static displacement and dynamic vibration, which are critical parameters in modern automated monitoring environments.
In automated process control systems, the 3300 XL 8 mm Proximity Probe is widely used for vibration monitoring, axial and radial position measurement, and rotational speed detection when integrated with a Keyphasor reference. The 330101-33-53-10-02-05 configuration is particularly suitable for fluid-film bearing machinery such as turbines, compressors, pumps, and large motors commonly found in power generation, petrochemical processing, and continuous manufacturing automation lines.
Engineered to meet stringent industry standards, the 3300 XL 8 mm Proximity Probe fully complies with API 670 requirements for linear measurement range, thermal stability, accuracy, and mechanical design. This compliance makes the 330101-33-53-10-02-05 3300 XL 8 mm Proximity Probe an ideal choice for safety-critical automation systems where reliable data acquisition is essential for predictive maintenance and equipment protection.
A major advantage of the 3300 XL 8 mm Proximity Probe system lies in its complete interchangeability. Probes, extension cables, and Proximitor sensors can be freely combined without individual calibration, simplifying installation and reducing commissioning time in automated plants. Additionally, the 330101-33-53-10-02-05 probe maintains backward compatibility with legacy 3300 series 5 mm and 8 mm components, supporting flexible upgrades within existing automation infrastructures.
From a mechanical perspective, the 3300 XL 8 mm Proximity Probe incorporates advanced design enhancements such as the patented TipLoc molding process, which strengthens the bond between the sensing tip and probe body. The integrated CableLoc technology further improves reliability by providing high pull-strength resistance, ensuring stable signal transmission even in harsh industrial automation environments. Optional FluidLoc cable construction is also available, preventing oil or fluid migration through the cable and protecting automation cabinets and control hardware.

Applications
1. Radial and Axial Vibration Monitoring in Rotating Machinery
The 330101-33-53-10-02-05 3300 XL 8 mm Proximity Probe is widely applied in radial and axial vibration monitoring of critical rotating equipment. With a 2 mm linear measurement range and a recommended gap setting of -9 Vdc, the probe provides highly stable and repeatable vibration signals. This makes it ideal for turbines, centrifugal compressors, pumps, motors, and generators equipped with fluid-film bearings. In automated condition monitoring systems, the probe enables early detection of imbalance, misalignment, shaft bow, and bearing wear, supporting predictive maintenance strategies.
2. Shaft Position and Displacement Measurement
Thanks to its output voltage that is directly proportional to probe-to-target distance, the 3300 XL 8 mm Proximity Probe is commonly used for shaft axial position and radial displacement measurement. The 3/8-24 UNF threaded stainless steel probe case and 5.3 in overall case length allow secure installation in machinery housings. In industrial automation environments, this application is essential for thrust bearing monitoring, ensuring safe machine operation and preventing axial rub or thrust overload conditions.
3. Keyphasor Reference and Speed Detection
In combination with a Keyphasor signal, the 330101-33-53-10-02-05 probe supports accurate rotational speed measurement and phase reference generation. This function is critical in automated vibration analysis systems, where precise speed data is required for order tracking, phase analysis, and machinery diagnostics. The probe’s 50 Ω output resistance and low supply sensitivity ensure signal integrity even in electrically noisy industrial environments.
4. High-Temperature and Harsh Industrial Environments
With an operating temperature range of -52°C to +177°C, a PPS probe tip, and AISI 303/304 stainless steel housing, the 3300 XL 8 mm Proximity Probe is suitable for harsh process industries such as oil & gas, petrochemical plants, power generation, and heavy manufacturing. Optional FluidLoc cable construction further enhances reliability by preventing oil or liquid migration, protecting automation cabinets and control systems.
