The Bently Nevada 330101-00-25-20-12-00 is a high-precision eddy current sensor designed for the 3300 XL series machinery protection system. This probe accurately measures the radial vibration and axial position of rotating shafts without physical contact. It serves as a vital component for monitoring the mechanical health of high-speed industrial assets. By providing real-time displacement data, this sensor helps operators identify early signs of bearing wear, shaft misalignment, and rotor imbalance.

Functional Benefits and Design Excellence
Bently Nevada engineered the 3300 XL 8mm probe to thrive in volatile industrial climates. It features an integrated temperature compensation system that maintains signal stability during thermal cycles. Consequently, the sensor provides accurate readings from -40°C to +177°C. The probe tip uses high-performance polyphenylene sulfide (PPS). This material effectively resists degradation from water, steam, and synthetic lubricants. Furthermore, the stainless steel body provides the necessary structural rigidity to withstand high-vibration mounting environments.
