Product Overview

The Bently Nevada 21508-02-12-10-02 is a precision-engineered proximity sensor designed for the non-contact measurement of shaft relative vibration, position (eccentricity), and speed in rotating machinery. As a core component of the Bently Nevada 7200 series, the 21508-02-12-10-02 utilizes eddy current technology to convert physical displacement into a proportional DC voltage signal. This specific model features a 10-meter integral cable, which allows for direct connection to monitoring racks or Proximitor sensors located at a distance from the measurement point, minimizing the need for extension cables and reducing potential signal loss points.

This sensor is critical for the protection and optimization of turbomachinery, including steam turbines, gas turbines, and centrifugal compressors. The 21508-02-12-10-02 is designed to operate in harsh industrial environments, providing reliable data that allows operators to detect early signs of machine degradation, such as bearing wear, misalignment, or rubs. By integrating the Bently Nevada 21508-02-12-10-02 into a machinery protection system, plant owners ensure compliance with API standards and maintain high levels of operational safety and efficiency.
