Product Overview

The Bently Nevada 144181-50-05 is a high-precision 3300 XL Proximitor Sensor, serving as a cornerstone for non-contacting displacement and vibration monitoring systems. This eddy current sensor is specifically calibrated for use with 5mm and 8mm probe tips, converting the electromagnetic interaction between the probe and the observed target into a linear DC voltage signal. By providing a continuous 4-20 mA output proportional to the gap distance, it allows for real-time machinery protection and diagnostic data acquisition. This model is engineered to maintain signal integrity in high-interference environments, facilitating the early detection of mechanical anomalies in critical rotating assets.
