Quick Detail

Description

The 330103-00-21-05-11-05 3300 XL 8 mm Proximity Probes are high-performance eddy current sensors designed for continuous machinery condition monitoring and protection in critical and hazardous industrial environments. As an integral part of proximity transducer systems, the 3300 XL 8 mm Proximity Probes deliver accurate, non-contact measurement of shaft vibration, axial position, and rotational reference, converting mechanical displacement into a stable and linear electrical signal for real-time analysis.

Engineered around a proven eddy current sensing principle, the 3300 XL 8 mm Proximity Probes provide fast response and excellent repeatability across a defined 2 mm (80 mils) linear measurement range. This precision allows early detection of mechanical issues such as imbalance, shaft eccentricity, misalignment, bearing degradation, and thermal growth. By capturing subtle changes in shaft position, the probes play a critical role in predictive maintenance programs and help operators avoid unexpected shutdowns and costly equipment damage.

The 330103-00-21-05-11-05 3300 XL 8 mm Proximity Probes are specifically configured for applications requiring extended probe body length and certified operation in hazardous areas. With an overall case length of 210 mm and zero unthreaded length, the probe is suitable for deep mounting locations, thick bearing housings, or installations where extended reach is required to achieve the correct target gap. The factory-integrated 0.5 meter cable with a miniature coaxial ClickLoc connector ensures secure signal transmission and simplifies installation while maintaining signal integrity.

Applications

The 3300 XL 8 mm Proximity Probes are used for continuous radial vibration monitoring on critical rotating machinery such as turbines, compressors, pumps, and large motors, providing precise shaft displacement data for early detection of imbalance, misalignment, and bearing wear in hazardous and non-hazardous environments.

For axial thrust position measurement, the 3300 XL 8 mm Proximity Probes monitor shaft movement relative to thrust bearings, helping prevent excessive axial displacement and protecting rotating equipment from mechanical contact, bearing failure, or forced shutdowns.

The probes are applied for Keyphasor reference and rotational speed detection by sensing keyways or notches on shafts, supplying accurate phase and speed signals required for balance analysis, startup and shutdown monitoring, and overspeed protection systems.

Specifications

Competitive Advantage

1. Certified Hazardous Area Compliance

With integrated CSA, ATEX, and IECEx approvals, the 3300 XL 8 mm Proximity Probes can be installed directly in Zone 1 and Zone 2 hazardous locations, reducing compliance risk, installation time, and overall project cost.

2. Extended Case Length for Complex Installations

The 210 mm overall case length and zero unthreaded design of the 3300 XL 8 mm Proximity Probes provide installation flexibility for deep or recessed mounting points, making them ideal for large machinery and thick bearing housings.

3. Stable Performance and Rugged Construction

Featuring a stainless steel probe case, PPS probe tip, wide operating temperature range, and low supply sensitivity, the 3300 XL 8 mm Proximity Probes deliver long-term measurement stability and durability in harsh industrial environments.
