Bently Nevada 135321-01 Dual Vibration Monitor Module

Product Overview

The Bently Nevada 135321-01 Dual Vibration Monitor belongs to the proven 3300/16 series for critical rotating machinery protection.
It continuously measures two independent vibration channels, enabling early fault detection and informed maintenance decisions.
Moreover, this module supports predictive maintenance strategies across turbines, compressors, pumps, and large industrial drives.

Key Features and Benefits

Dual-channel architecture allows simultaneous monitoring of two vibration points on a single machine asset.
Therefore, engineers can compare shaft or casing behavior without adding extra monitoring hardware.
High measurement sensitivity ensures small vibration changes are detected before failures escalate into serious damage.
In addition, hermetically sealed alarm relays provide dependable operation in dusty, humid, or high-vibration environments.
The rugged industrial design supports continuous operation across wide temperature ranges and harsh plant conditions.
