Product Description
228‑02‑21‑56‑61 is an eddy‑current proximity probe manufactured by Bently Nevada, part of the 3300 sensor system. It adopts non‑contact eddy‑current measuring principle to collect signals of shaft radial vibration, shaft displacement and axial position for rotating machinery. This probe comes with integrated 5‑meter cable and works with matched proximitor sensor. It outputs standard displacement signal to monitor rack, features excellent anti‑interference performance for industrial environment. It is a core sensing component for critical units such as steam turbines and compressors, widely used as spare replacement part.
