Bently Nevada 3300/45 Dual Differential Expansion Monitor
Product Overview
The Bently Nevada 3300/45 Dual Differential Expansion Monitor is a rack-mounted module designed to measure the relative axial expansion between a turbine shaft and its casing. It forms a key part of the 3300 series machinery protection system, providing critical information during thermal expansion and startup conditions. With two independent channels, the module supports both redundant and comparative measurement strategies, enabling precise and reliable monitoring of differential expansion in large rotating equipment.
