DEF sensor innovation and development is<br />
driven by emission legislation<br />
• Ensuring that sensors and tanks<br />
work well together as a system is<br />
critical for reliable operation<br />
• Thawing requirements must be<br />
met with customized heat<br />
exchangers, temperature<br />
monitoring and control of the<br />
coolant flow<br />
• New vehicle/engine platforms<br />
based on requirements of coming<br />
legislations Euro VI, EPA2013,<br />
Stage 3b/4, …
Usage of low quality NOx reduction<br />
agents puts your assets at risk<br />
• The international standard ISO22241 specifies quality<br />
characteristics for the “NOx reduction agent AUS32” (DEF)<br />
– The main characteristic is the urea content, with a concentration of<br />
32.5%.<br />
• DEF is subjected to quality risks over its lifecycle<br />
– Contamination<br />
– Misfilling the DEF tank<br />
– Tampering<br />
– Temperature variations<br />
– Different concentrations yield different freezing points<br />
Quality of DEF can be measured by speed of<br />
sound and appropriate algorithms<br />
• Quality measurement is<br />
optionally implemented using<br />
ultrasound technology<br />
– Speed of sound + temperature +<br />
algorithm determines the quality<br />
with an accuracy of ±0.5%<br />
– Measurement can be executed<br />
as long as DEF is in liquid form<br />
Challenge: In the tank technology –<br />
harshest environment but optimal protection
Asset protection is crucial for our<br />
customers and vehicle owners<br />
Conductivity measurement supports the exclusion of incompatible liquids<br />
• Many liquids can be excluded through ultrasound measurement as their speed of<br />
sound is outside the range for DEF<br />
• A conductivity sensor is an option to evaluate if another liquid than DEF is present<br />

What are customer requirements to<br />
achieve SCR system functionality?<br />
• Quality measurement<br />
• Protection from harmful liquids<br />
• Filtration of contaminant<br />
particles and dirt<br />
• Level measurement, suction,<br />
return and air venting<br />
• In tank temperature<br />
measurement<br />
• Thawing capabilities<br />
• Leak proof construction<br />
• Robust, durable and reliable in<br />
harsh environmental conditions<br />
• System integration<br />
– Sensor and tank<br />
– Sensor and dosing control unit (SCR<br />
system)<br />
– Vehicle management systems<br />
– Bus communication<br />
• Parameter customization e.g.<br />
quality thresholds<br />
• Predefined scenarios for driving<br />
conditions<br />
• Customized Failure Mode<br />
Indication (FMI)<br />
