Bently Nevada 3300/45-02-02-03-00 Dual Differential Expansion Monitor

Description Differential Expansion measures the axial position of the rotor relative to the machine casing at a distance from the thrust bearing. Changes in axial position affect axial clearances and are typically caused by thermal expansion during startup and shutdown. This measurement is usually taken with a proximity probe transducer mounted to the machine casing, observing an axial surface (e.g., collar) of the rotor. It is commonly part of a Turbine Supervisory Instrumentation system. 3300/45-AXX-BXX-CXX-DXX Configuration Options A: Full-scale Range Option 0: 0 - 10 mm 2: 35 mm B: Transducer Input Option 0: Standard option 2: For use with 35 mm transducers C: Alarm Relay Option 0: No relay 3: Quad Relay (Epoxy-sealed only) D: Agency Approval Option 0: Not required
