📦 Product Overview
Model: 3500/63 163179-04
Brand: Bently Nevada
Series: 3500 Series – Hazardous Gas Monitor
The Bently Nevada 3500/63 163179-04 Hazardous Gas Monitor is designed to provide continuous monitoring of flammable or combustible gas concentrations in industrial environments. It supports up to six sensor inputs, capable of detecting gases such as hydrogen or methane through catalytic bead-type sensors. It offers a robust safety layer for process control systems, particularly in enclosed or potentially explosive environments.
This module is part of the highly reliable 3500 Series, which provides machinery protection and condition monitoring for critical equipment. It integrates seamlessly into existing 3500 rack systems and is compatible with both simplex and redundant (TMR) configurations.
