Main Features and Advantages

Non-Contact Measurement for Extreme Durability: The 21500-00-36-05-02 utilizes non-contact eddy current sensing, which means there is no physical wear on the probe tip or the shaft surface. This is a significant advantage over contact sensors, as it eliminates the need for frequent replacement due to mechanical wear. The sensor is immune to dirt, oil, and water on the shaft surface, making it highly reliable in the harsh environments typical of power generation and petrochemical plants.

High-Frequency Response for Critical Applications: With a frequency response extending up to 10.000 Hz, the 21500-00-36-05-02 is capable of capturing high-frequency components of shaft vibration, such as those caused by rubs or oil whirl. This high bandwidth ensures that the signal fed into the 3500 monitor is rich in detail, allowing the system to distinguish between normal operational vibration and potentially damaging fault conditions. The 11 mm diameter is chosen for its balance between spatial resolution and mechanical robustness.

Plug-and-Play Compatibility: The 21500-00-36-02 is designed to work seamlessly within the Bently Nevada ecosystem. The Mini-DIN connector and specific cable length (3 meters) ensure that the electrical characteristics of the transmission line are matched, preventing signal reflections that could distort the measurement. This module is often used in pairs (X and Y axes) to provide a complete picture of shaft motion in a single plane. The assembly is calibrated at the factory to ensure consistent performance across all units.
