Overview

The Bently Nevada 3300/45-02-01-03-00 Dual Differential Expansion Monitor offers advanced monitoring for industrial machinery. It features two channels of continuous differential expansion monitoring, precisely measuring both the magnitude and direction of expansion. The monitor is ideal for applications where accurate expansion measurements are critical.

This model allows for easy alarm configuration with four adjustable alarm setpoints per channel. One channel (Channel B) can be disabled, making it suitable for machines that only require monitoring at a single location.
