Bently Nevada 21508-02-12-05-02 7200 8mm Reverse Mount Probe

مقدمة المنتج

The Bently Nevada 21508-02-12-05-02 is a reverse-mount proximity probe designed for high-precision non-contact measurement من shaft vibration and position in rotating machinery. As part من the renowned 3300 XL series, this 8mm eddy current sensor is specially engineered for applications where front access to the machine shaft is restricted or impossible.

It is commonly paired with matching extension cables and proximity transducers (Proximitor® sensors) to form a complete measurement chain. Designed with robustness, linear accuracy, and environmental resilience, the 21508-02-12-05-02 is a trusted solution in industries such as oil & gas, power generation, and heavy equipment manufacturing. This reverse-mount configuration is particularly valuable in tight, enclosed, or high-temperature machinery environments.
