The Tasseron Sensors and Controls Qwik Average duct averaging sensor is used to take an average reading in large ductwork, and send that information back to a controller. The product monitors and transmits changes in duct air temperature to the building control system. They are compatible with whatever building automation system is installed and provide accurate, reliable indication of duct temperature. The Qwik Average comes with two types of housings: galvanized box housing, or injection-molded polycarbonate housing. They both feature two U.S. patents; patent-pending Qwik Connects and patent-pending Qwik Coupling.
Copeland Scroll™ Compressors with CoreSense™ Communications
The Copeland Scroll™ Compressors with CoreSense™ Communications by Emerson Climate Technologies features an onboard communications module for Copeland Scroll™ compressors within commercial air conditioning systems. Copeland Scroll compressors with CoreSense Communications technology streams diagnostics information on the compressor's operation to the system controller. By using the compressor as a sensor, valuable data from inside the system can be accessed and monitored by the controller, improving performance and reliability – even proactively shutting down the compressor to prevent a catastrophic failure.
