Products Description
The Bently Nevada 330703-000-050-10-12-CN 3300 XL 11 mm Proximity Probe is engineered for precise and reliable machinery monitoring in challenging industrial environments. This probe is available in multiple case configurations, including armored and unarmored threads (1/2-20, 5/8-18, M14×1.5, and M16×1.5), with reverse mount options featuring 3/8-24 or M10×1 threads. Each probe features a gold-plated brass ClickLoc connector that locks securely to prevent loosening, and the TipLoc molding method ensures a robust bond between the probe tip and body.
The CableLoc design provides 330 N (75 lb) pull strength for reliable cable attachment. Optional FluidLoc cables prevent oil leakage, while connector protectors or silicone tape provide enhanced environmental protection in humid or moist conditions. Standard locknuts with pre-drilled safety wire holes further secure installation. Factory calibration to AISI 4140 steel ensures accurate measurements, with calibration to other materials available on request, making this probe ideal for turbine, generator, and high-speed rotating machinery monitoring.
