Bently Nevada 3500/93 135785-02 Display Unit, backlighted

The Bently Nevada 3500/93 (Part Number 135785-02) serves as the primary local interface for the 3500 Series Machinery Protection System. This backlit display unit provides operators with immediate access to critical machinery data directly at the equipment rack. It displays vital parameters including vibration levels, axial positions, and temperature readings. By utilizing a high-visibility liquid crystal display, the module ensures clear data visualization even in low-light industrial environments.

Core Functionality and Applications

Engineers integrate this display unit into the 3500 rack to facilitate real-time monitoring of Turbo-machinery Instrumentation (TSI). The module connects to the 3500/22M Transient Data Interface to pull system events and current values. It functions as a diagnostic window for plant personnel during startup, steady-state operation, and troubleshooting phases. Common deployment sites include power generation facilities, petrochemical plants, and offshore oil platforms where local status indication remains a safety requirement.
