Bently Nevada 330106-05-30-10-02-CN 3300 XL 8mm Proximity Probe

High-Performance Non-Contact Displacement Sensing

The Bently Nevada 330106-05-30-10-02-CN operates as a fundamental sensing component of the 3300 XL Proximity Transducer System. This eddy-current probe measures the static and dynamic distance between the probe tip and a target conductive surface, typically a rotating machine shaft. By converting these physical displacements into proportional electrical signals, the 330106-05-30-10-02-CN provides critical data regarding radial vibration and axial position. Consequently, this transducer allows maintenance engineers to monitor machinery health in real-time, facilitating the early detection of mechanical anomalies such as shaft bow, rotor unbalance, or fluid-film bearing wear.

Robust Design for Extreme Industrial Environments

The 330106-05-30-10-02-CN maximizes durability through its specialized Ryton® probe tip and stainless steel case construction. This combination provides superior resistance to corrosive process fluids and high-pressure environments. Furthermore, the 3300 XL series features a patented ClickLoc™ connector system, which prevents moisture ingress and ensures a vibration-proof electrical connection between the probe and extension cable. Since the probe utilizes advanced internal compensations, it maintains a highly linear scale factor even when subjected to significant temperature fluctuations. Moreover, the “CN” designation ensures the unit complies with specific regional regulatory standards, allowing for seamless legal integration into large-scale power and petrochemical projects within its certified markets.
