Bently Nevada 3300/46-08-03-01-00 Differential Expansion Monitor
Product Overview
The Bently Nevada 3300/46-08-03-01-00 Differential Expansion Monitor is part of the trusted 3300 Series of machinery protection modules, engineered for detecting axial movement (differential expansion) between a rotating shaft and its casing. This function is crucial in large steam turbines, gas turbines, and similar high-temperature rotating machinery, where unmonitored thermal growth can lead to severe equipment damage. The module delivers real-time measurement, configurable alarms, and relay outputs to ensure operational safety and asset protection.
