Bently Nevada 3300/46 Expansion Monitor

Wondering how the Bently Nevada 3300/46 Expansion Monitor works in real-world applications? In this video, we demonstrate the specialized ramp differential expansion monitoring logic used to measure thermal growth between rotor and stator in steam turbines. You'll see how this legacy monitor uses two proximity probes to prevent internal contact during startup and shutdown phases, and learn about its industrial-grade relay protection and hazardous area certifications for power plant and refinery environments.
