The fluid level in the DEF tank is measured by the DEF level sensor, which is a component of the DEF sending unit.
The DEF level sensor notifies the vehicle’s ECU when the liquid level is low, which activates the warning light on the gauges or panel.
On the side of the DEF tank is a sensor for measuring DEF quality. This sensor measures the amount of urea in the DEF to determine whether it is appropriate for successful dosage.
Chemically speaking, DEF is a mixture of deionized water and urea that converts dangerous nitrous oxide emissions into safe water and gas.
The storage tank is typically located either close to the spare tire on a car or next to the diesel fuel tank on a truck.
The Global DEF Level Sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A combined SCR System DEF sensor to monitor urea level, temperature, and concentration was launched by SSI Technologies, a creator and producer of ultrasonic level, pressure, and magnetic sensors and monitoring systems.
DEF sensors are made to comply with upcoming international emissions rules that will call for on- and off-road OEMs to keep an eye on the quality and concentration of DEF in order to comply with statutory emissions control for SCR systems.
According to SSI, their combo sensor makes use of tried-and-true ultrasonic technology and has both OBD and an in-tank design. Critical measurements and capabilities are provided by the sensor.
detection of water dilution of DEF of 10% or more, detection of impurities in DEF, including water, motor oil, gasoline, windscreen washer fluid, brake fluid, and diesel fuel monitoring of DEF levels at high precision (0.5 mm) for OEM operator information, notification of any diesel miss-fills in the DEF tank to the operator immediately, accurate (+/- 3 C) temperature monitoring for DEF heating management redundant DEF tank empty indication Technology J1939 CAN-Bus for quick system integration, Regular or irregular/odd shaped DEF tanks can be profiled using programming.
