Bently Nevada 330400-02-00 Accelerometer Acceleration Tranducer

Overview

The Bently Nevada 330400‑02‑00 is an industrial‑grade accelerometer designed for casing vibration measurements on critical rotating machinery. As part of Bently Nevada’s acceleration transducer family, it provides high‑fidelity vibration data for diagnostics, machinery protection, and predictive maintenance programs in demanding industrial environments.

Functional Characteristics

This accelerometer delivers a nominal sensitivity of 100 mV/g, making it suitable for detecting both low‑amplitude and broadband vibration signatures. Its stainless‑steel housing and hermetically sealed construction ensure long‑term stability in harsh operating conditions, including refineries, petrochemical plants, and power generation facilities.

The 330400‑02‑00 features an integral armored cable that protects the signal path from mechanical damage and electromagnetic interference. Its wide usable frequency range supports both low‑frequency casing vibration and high‑frequency gear mesh or bearing fault detection.
