1. Product Overview — Bently Nevada 3300/12‑01‑20‑01
Introduction
The 3300/12‑01‑20‑01 is a module in the 3300 series of rack/monitor modules, often used within the 3300 instrumentation rack to deliver specific auxiliary functions—such as power supply, barrier module, signal processing, or internal monitor support. The “12” prefix often denotes a power or rack support class in the 3300 family. The suffixes “01‑20‑01” represent internal options (voltage type, barrier presence, agency approvals, etc.). In many 3300 systems, the “12” modules supply regulated DC voltages to the monitor modules and sensors (transducers), or provide internal isolation / barrier circuits.
In short, 3300/12‑01‑20‑01 likely is a power / barrier / supply support module rather than a direct proximitor sensor. It ensures stable and clean power and isolation for the 3300 monitor modules and transducer chain.
