Product Introduction
The Bently Nevada 330703-005-040-10-02-00 3300 XL 11 mm Proximity Probe is a high-precision, non-contact vibration and displacement measurement device engineered for demanding industrial applications. Designed as part of the 3300 XL series, this probe represents Bently Nevada’s long-standing commitment to providing reliable and accurate machinery protection and condition monitoring solutions.
This proximity probe utilizes eddy-current sensing technology to detect the distance between the probe tip and a conductive target, such as a rotating shaft. It delivers a highly linear output signal proportional to the target’s displacement, making it ideal for monitoring shaft vibration, axial position, and key phase reference measurements in critical rotating machinery.
The 330703-005-040-10-02-00 is optimized for use with Bently Nevada 3300 XL Proximitor Sensors and extension cables, forming a complete transducer system that complies with API 670 standards for vibration monitoring and machinery protection. Engineered for reliability, it ensures stable signal transmission even under harsh environmental conditions such as oil, heat, and electromagnetic interference (EMI).
Built with corrosion-resistant stainless steel and high-temperature insulation materials, this proximity probe guarantees long-term operational stability and accuracy, making it a trusted component in power generation, oil and gas, petrochemical, and heavy industrial environments.
