The STEMCO Aeris SmartSense technology is an advanced driver alert system that identifies which wheel ends are taking air for faster corrective action. The included Zero Power Technology notifies the maintenance team which tires need service, even when the trailer is disconnected from power. When power is disconnected, service icons remain displayed on the indicator to inform the technician which tires took air during the last trip and which wheel ends are frequently taking air. The system is also equipped with a radio frequency link between the Aeris control box and the driver-warning lamp that can eliminate the need for the fleet maintenance crew to install a hardwire link.
