Product Overview

The Bently Nevada 18745-03 is a high-performance 5.8 mm Proximitor sensor designed for precision non-contact displacement and vibration measurement. As a core component of the Bently Nevada 3300 XL and 3500 Machinery Protection Systems, this sensor utilizes eddy current technology to provide accurate readings of shaft relative vibration, position, and speed. The Bently Nevada 18745-03 is engineered to operate reliably in harsh industrial environments, offering immunity to oil, water, and other contaminants that typically affect conventional sensors.

This specific model features a 5.8 mm diameter probe tip, which is optimized for measuring smaller shafts or applications where space is limited. The Bently Nevada 18745-03 delivers a linear output proportional to the distance between the probe tip and the conductive target material, typically steel. With its robust construction and high-frequency response, the Bently Nevada 18745-03 is capable of detecting rapid changes in shaft position, making it an essential tool for preventing catastrophic machinery failure in turbines, compressors, and pumps. The sensor is designed to be used in conjunction with a compatible Proximitor power supply or monitor, forming a complete measurement chain that meets API 670 standards for machinery protection.
