Product Description
The 330105-02-12 is a component of the Bently Nevada 3300 Monitoring System, specifically identified as an 8 mm Proximity Transducer Assembly. This model represents a pre-configured package that includes an 8 mm eddy current proximity probe and a permanently attached cable. The suffixes "-02-12" typically specify the connector type and cable length. In this context, it is designed as a direct, "Tip-to-Connector" solution for measuring shaft vibration, position (gap), and rotational speed (Keyphasor®) on critical rotating machinery. This integrated assembly ensures signal integrity and simplifies installation by eliminating separate components.
