Quick Detail

Description

The Bently Nevada 21504-000-016-10-02 Proximity Probe is a high-precision industrial sensor designed for non-contact measurement of shaft displacement, vibration, and position in rotating machinery. With an 8 mm diameter and a total length of 1.0 metre, this probe provides accurate measurement over extended distances, while maintaining a calibrated output range of 80 mils (2.0 mm) beginning at 0.25 mm (10 mils) from the probe face. It operates reliably across extreme temperatures from -51°C to +177°C (-60°F to +351°F), making it suitable for harsh industrial environments including turbines, compressors, and generators.

Equipped with a miniature male coaxial connector and a standard 3/8-24 threaded configuration, the 21504-000-016-10-02 probe integrates easily into existing monitoring systems. The sensor’s low-power design, requiring -17.5 Vdc to -26 Vdc at 12 mA max, ensures minimal energy consumption while providing precise and repeatable data. Its compact overall case length of 0.8 inches allows installation in tight spaces without compromising measurement accuracy. This probe is ideal for automation systems requiring reliable, high-fidelity vibration and displacement monitoring for predictive maintenance and operational optimization.

Applications

High-Temperature Process Equipment
With a storage range up to +177°C, this probe functions in extreme industrial environments, including petrochemical and power plants, maintaining measurement accuracy under high thermal stress.

Automation and SCADA Integration
The probe outputs a calibrated 4–20 mA signal equivalent, enabling seamless integration with SCADA, DCS, or PLC systems for predictive maintenance analytics.

Compact and Flexible Installation
Its 0.8-inch case length and 1.0-metre cable allow installation in confined spaces, supporting monitoring of fans, pumps, and other rotating machinery in tight automation layouts.
