Armored Eddy Current Probe for Precise Shaft Displacement and Machinery Protection
The Bently Nevada 330102-04-16-10-02-00 3300 XL 8 mm Proximity Probe is a high-reliability non-contact displacement sensor designed for continuous monitoring of rotating equipment. Utilizing advanced eddy current sensing technology, this probe provides accurate measurement of shaft vibration, radial position, and axial displacement for critical machinery protection and predictive maintenance systems.
As an armored member of the 3300 XL 8 mm Proximity Probe family, the 330102 series is engineered for installations where additional cable protection is required. The 330102-04-16-10-02-00 configuration features a 3/8-24 UNF threaded probe body, 0.4-inch unthreaded length, 1.6-inch case length, 1.0-meter cable, miniature coaxial ClickLoc™ connector, and connector protector. Its rugged armored construction improves resistance against mechanical stress, vibration, and industrial operating conditions.
