Hot sale 2011650 5wk96626c Truck Scr Part Nitrogen Oxygen Sensor Truck Nox Sensor 24v For Daf
Product performance advantage
1 The measurement range is twice as large as similar imported products
2 Start-up time is less than 10s of similar imported products.
3 The measurement accuracy fluctuation is lower than similar imported products
4 Product induction time is ahead of similar imported products
Response time
When the NOx concentration in the measuring gas changes from 0 to a certain value, the
sensor will output 10% of the final value to 90% of the final value. When the NOx concentra-
tion in the measuring gas changes from a certain value to 0, the sensor will output an initial
value of 90 % To the time required to output 10% of the initial value

Range of working temperature
Start Time
The sensor is placed in the air at a temperature of 25t5°C. After the rated voltage is applied to the sensor SCU. the time between the start and the effective
function data is recorded
The characteristic start-up time of NOx sensor is less than 90s
Operating Voltage
10.8≤V≤36.0
The nitrogen and oxygen sensor product consists of a sensor probe and an electronic control unit (Secondary Control Unit, hereinafter referred to as the electronic control
unit (controlle/),. which are connected by a wire harness In actual application, the probe is installed in the exhaust pipe of the car, and the NOX concentration value in the exhaust is fed back to the electronic control unit (controller) in the form of current. The electronic control unit (controller) communicates through the CAN bus to measure.The gas value is sent to the car control center in real time (ECU),to provide a basis for SCR injection volume to reduce NOX emissions
