Quick Detail

Description

The 330103-01-04-10-02-05 3300 XL 8 mm Proximity Probes are advanced eddy current sensors designed for high-reliability industrial automation, machinery protection, and condition monitoring systems. As a core component of the 3300 XL 8 mm Proximity Probes family, this model delivers a highly linear output voltage that is precisely proportional to the distance between the probe tip and a conductive target surface. This enables accurate monitoring of both static position and dynamic vibration, which is essential for modern automated machinery.

Within automated process control environments, the 3300 XL 8 mm Proximity Probes are widely used for vibration measurement, axial and radial position monitoring, speed detection, and Keyphasor® reference signals. The 330103-01-04-10-02-05 probe is particularly suitable for fluid-film bearing machines such as turbines, compressors, pumps, motors, and generators commonly found in oil & gas, petrochemical, power generation, and heavy industrial automation systems.

Engineered to meet stringent industry requirements, the 3300 XL 8 mm Proximity Probes fully comply with API 670 standards for linear range, accuracy, mechanical configuration, and thermal stability. This compliance ensures reliable operation in harsh automation environments where temperature variation, vibration, and continuous operation are unavoidable. The standardized design also supports complete interchangeability between probes, extension cables, and Proximitor® sensors, eliminating the need for individual calibration and significantly reducing maintenance time in automated plants.

The 330103-01-04-10-02-05 3300 XL 8 mm Proximity Probes incorporate enhanced mechanical durability through patented design improvements. The TipLoc™ molding technology strengthens the bond between the probe tip and housing, increasing resistance to mechanical stress during installation and long-term operation. In addition, the CableLoc™ strain-relief design provides up to 330 N (75 lbf) of pull strength, ensuring secure cable attachment in vibration-intensive automation systems.

For automation applications involving lubricated or sealed machinery, optional FluidLoc™ cable technology is available. This feature prevents oil or process fluids from migrating through the cable assembly, maintaining system integrity and reducing the risk of contamination or sensor failure.

Backward compatibility with legacy 3300 series 5 mm and 8 mm systems allows the 3300 XL 8 mm Proximity Probes to be easily integrated into existing automation infrastructures. Overall, the 330103-01-04-10-02-05 model provides a robust, accurate, and automation-ready solution for continuous machinery monitoring and protection in demanding industrial environments.

Applications

Vibration Monitoring in Fluid-Film Bearing Machinery

The 330103-01-04-10-02-05 3300 XL 8 mm Proximity Probe is widely applied in radial and axial vibration monitoring of fluid-film bearing machines. With a 2 mm linear measurement range and a recommended gap setting of –9 Vdc, the probe delivers precise vibration signals required by automated condition monitoring systems. Typical applications include steam turbines, gas turbines, centrifugal compressors, large pumps, motors, and generators used in continuous industrial automation environments.

Shaft Position and Displacement Measurement

In automated rotating equipment, accurate shaft position feedback is critical for maintaining mechanical integrity. The 3300 XL 8 mm Proximity Probes provide highly stable static position measurement by converting shaft displacement into a proportional voltage output. The M10 × 1 threaded probe case and 40 mm overall case length allow flexible installation in limited mounting spaces, making this probe suitable for thrust position monitoring and shaft centerline analysis in high-speed machinery.
