1. Product Overview — Bently Nevada 3300/53‑03‑01‑00‑01
Product Introduction
The 3300/53 family is designed as a speed / tachometer / overspeed protection module in the Bently Nevada 3300 rack system. The “03–01–00–01” suffix designates a particular internal configuration: “03” series of 53, “01” sub‑variant, “00” baseline, “01” a specific minor revision or feature set. This module receives rotor speed input (from proximity probe, magnetic pickup, or keyed speed sensors), analyzes for valid rpm, can detect reverse rotation, and offers overspeed alarm or trip logic.
This variant is intended to fit into a 3300 monitoring rack, providing essential speed and protection functionality for rotating machinery. It may include front-LED status, internal logic, and relay outputs for alarm/trip.
