Product Overview
The Bently Nevada 330191-00-33-90-05 3300 XL 8 mm ETR Probe is an industrial proximity probe designed for accurate non-contact measurement of shaft displacement, vibration, and relative movement in rotating machinery. It is a critical sensing component used in machinery protection and condition monitoring systems where reliable operating data is required.
The probe utilizes eddy current sensing technology to continuously monitor the position and movement of rotating shafts. By providing accurate measurement signals to monitoring electronics, it helps operators detect abnormal machine conditions such as excessive vibration, shaft misalignment, mechanical wear, and other potential failures.
The Bently Nevada 330191-00-33-90-05 features a total length of 9 meters and an approximate weight of 2.907 kg. The extended cable length makes it suitable for large industrial equipment installations where the sensor location is far from the monitoring system.
