Manager’s Insight
This probe is ideal for high-speed turbomachinery including steam turbines, compressors, and large pumps. The 5-meter total length eliminates extension cables in remote installations. The ia rating supports intrinsically safe applications with proper barriers.
Expert Review
The 3300 XL series delivers proven linearity and repeatability. The 8 mm probe provides excellent sensitivity for detecting small shaft movements. The Viton® seal reliably prevents process fluid ingress. For modular systems, pair with extension cables like 330190-085-00-CN or 330190-085-00-05.
Frequently Asked Questions (FAQ)
- What is the maximum cable length without signal degradation?This 5.0-meter probe works only with the 5-meter Proximitor sensor. Longer runs need extension cables with proper impedance matching.
- Can this probe be used in wet or corrosive environments?Yes. Stainless steel case and PPS tip resist corrosion. The Viton® O-ring provides moisture sealing.
- How do I verify probe health before installation?Measure DC resistance between center and outer conductors. Expected reading is 8.73 ± 0.50 Ω.
- What is the difference between 8 mm and 5 mm proximity probes?The 8 mm probe offers larger target area and different linear range. For smaller shafts, consider the 3300 5mm Proximity Probes series.
- What mounting torque is required?Apply 15-20 ft-lbs for the 3/8-24 UNF thread. Ensure at least 0.8 inches of unthreaded length relative to case length.
- Is pressure seal testing included?No. Probes are not pressure tested before shipment. Contact custom design department if testing is required.
