Introduction
CoreSense
™ is an ingredient brand name for compressor electronics associated with Emerson’s Copeland™
brand products. CoreSense technology uses the compressor as a sensor to unlock information from within the
compressor providing value added features such as advanced motor protection, diagnostics, power consumption
measurement and communication.
With active protection, advanced algorithms, and features like fault history and LED indicators, CoreSense
Diagnostics for Copeland brand products compressors enable technicians to diagnose the past and recent state of
the system, allowing for quicker, more accurate diagnostics and less downtime. CoreSense Diagnostics is available
as standard with the 4- and 6-cylinder Stream compressors.
