SSI Technologies' selective catalytic reduction system diesel exhaust fluid (DEF) combination sensor monitors urea level, temperature, and concentration and is designed to meet pending worldwide emissions regulations for on- and off-highway OEMs. The combination sensor is an in-tank design with onboard diagnostic capability that uses ultrasonic technology and offers detection of 10% or greater water dilution of DEF; detection of DEF contaminants such as diesel fuel, water, windshield fluid, brake fluid, motor oil, gasoline, and anti-freeze; 0.5-mm (0.02-in) resolution DEF level monitoring; operator notification of any diesel miss-fills; temperature monitoring for heating management; and redundant indication of empty tank. The sensor is programmable for profiling to regular- or irregular-shaped DEF tanks.
