Bently Nevada 990-08-XX-03-00 Vibration Transmitter

Overview

The Bently Nevada 990‑08‑XX‑03‑00 is a compact, two-wire, loop-powered vibration transmitter designed for continuous machinery monitoring. It converts vibration signals from 3300 NSv proximity probes into a standardized 4–20 mA output for direct integration with PLCs, DCS, or protection relays. This device provides reliable peak-to-peak vibration measurements in a simple, rugged form factor ideal for OEM machinery applications.
