Bently Nevada 21500-00-16-05-02

Product Overview

The 21500-00-16-05-02 operates as a proximity probe within the Bently Nevada 21500 series. This sensor measures shaft displacement and vibration without touching the target surface. Consequently, engineers gain reliable position data for turbines, compressors, and other rotating machinery.

Construction and Materials

The probe tip uses polyphenylene sulfide, which resists abrasion and chemical exposure. Meanwhile, the stainless steel housing delivers rugged protection during continuous duty. The integral cable ends in a coaxial connector, so technicians achieve fast mating without special tools.

Interface and System Compatibility

This probe pairs with compatible extension cables and Proximitor sensors. Additionally, its 75 Ω impedance maintains signal fidelity across the measurement chain. Therefore, readings stay stable even when cable lengths differ between installations.

Installation Guidelines

A target measuring at least 40 mm wide ensures complete linear range coverage. Furthermore, technicians must observe side clearance and cable bend radius limits. Correct gap voltage adjustment directly influences measurement accuracy, so verify it after every mounting change.
