Reliable Eddy-Current Sensing for High-Performance Rotating Machinery
The Bently Nevada 330101-05-20-10-02-00 3300 XL 8 mm Proximity Probe is a precision-engineered eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, radial displacement, and position. As part of the industry-proven 3300 XL series, it provides stable signal output, strong electromagnetic immunity, and long-term operational reliability in demanding industrial environments.
This configuration is typically defined by a 0.5-inch unthreaded length (05), 2.0-inch case length (20), 1.0-meter system cable (10), ClickLoc connector (02), and standard approval option (00). It is widely used in turbine and compressor monitoring systems where consistent accuracy and interchangeability are critical for machinery protection and predictive maintenance strategies.
Built with stainless steel housing and a PPS sensing tip, this probe is designed to withstand harsh operating conditions such as high vibration, temperature fluctuations, and industrial contamination.
