TECHNICAL OVERVIEW

OPERATING PROFILE

Differential Expansion for ENTEK IRD 6600 Series

Technical data below is separated from the product overview and excludes shipping weight and package dimensions.

Performance & Efficiency

Independent channel processing, configurable sensitivity and Alert/Danger setpoints support clear differential-expansion supervision. Event storage and first-out information help operators trace the condition that initiated a machine alarm.

Application Scenarios

Applied to steam and gas turbines where rotor-to-casing movement must remain within operating limits during startup, loading and shutdown. It also supports compressor-train and other critical rotating-equipment protection programs.
