TULC Sensor

SSI Technologies, LLC introduces our TULC Sensor, an in-tank combination sensor for accurate, reliable measurement of temperature, level, and fluid quality/concentration, for SCR Diesel Exhaust Fluid (DEF) tanks to meet legislated mandates for cleaner diesel emissions.

Governments around the world are creating legislation to control and reduce the number of pollutants that can be released into the environment.

Starting in January 2010, UREA tanks became standard equipment for most new diesel trucks, buses, sport utility vehicles and automobiles in the U.S. Tractors, bulldozers, and other non-road vehicles will follow to meet the new EPA standards.

Running without UREA or with contaminated UREA results in an engine exceeding the permitted emission levels while vehicle operators are subject to fines.

Critical features include:

  • Detection of water dilution
  • Detection of contaminants such as diesel, gasoline, and oil
  • Immediate improper fill notification
  • Accurate temperature monitoring for DEF tank heat management
  • Programmable for regular/irregular shaped tank
  • J1939 CAN-bus technology for ready system integration
  • Proven and tested ultrasonic technology
