The Bently Nevada 330104-00-06-50-20-00 Proximity Probe Module is a high-precision non-contact eddy-current sensor developed for advanced vibration and position monitoring of rotating equipment. As part of the globally recognized 3300 XL 8 mm Proximity Transducer System, this probe delivers exceptional measurement accuracy, reliable signal stability, and outstanding durability in demanding industrial environments.
Designed with a 60 mm probe case length (Option 06) and an extended 5.0-meter total system length (Option 50), this model provides increased installation flexibility for large machinery trains and remote monitoring cabinet configurations. The Option 20 connector configuration is engineered to support specialized installation requirements while maintaining full compatibility with Bently Nevada machinery protection systems.
Whether installed on steam turbines, gas compressors, centrifugal pumps, or high-speed motors, the 330104-00-06-50-20-00 provides the accurate machine condition data required to maximize equipment reliability, reduce maintenance costs, and support predictive maintenance initiatives.
By continuously monitoring shaft movement without physical contact, the probe helps maintenance personnel identify developing mechanical issues before they evolve into expensive failures or unplanned shutdowns.
