Product Introduction
The Bently Nevada 330709-016-240-50-02-00 3300 XL 11 mm Proximity Probe is a high-precision, non-contact displacement and vibration sensor, specifically designed for industrial machinery monitoring. As part of the 3300 XL Series, it offers exceptional reliability, accuracy, and stability in harsh operational environments such as turbines, compressors, pumps, and motors.
This probe uses the eddy current principle, generating an electromagnetic field near a conductive target (typically a rotating shaft). Variations in this field are converted into a voltage signal proportional to the shaft displacement or vibration. When combined with a 3300 XL Proximitor Sensor and extension cable, the system provides real-time, high-resolution monitoring for predictive maintenance and machinery protection.
The 330709-016-240-50-02-00 is constructed with stainless steel, offers excellent temperature resistance, and features double-shielded coaxial cable for superior EMI/RFI immunity. Designed to comply with API 670 standards, this probe ensures dependable performance in critical machinery applications across power generation, petrochemical, and industrial sectors.
