Nitrogen Oxide Sensor
Product Introduction: The nitrogen oxide sensor is installed on the catalytic muffler of the exhaust gas after-treatment system to measure the concentration of nitrogen oxides. It is used for closed-loop detection and control of nitrogen oxide signals and OBD requirements. The controller detects the Nox signal and sends instructions to the actuator to work to achieve the purpose of controlling emissions.

Exhaust temperature sensor
The product is installed on the catalytic muffler of the exhaust gas after-treatment system. It detects the exhaust gas temperature signal through PT200, and the post-treatment controller controls the urea injection status based on the exhaust temperature signal to achieve the purpose of controlling emissions. Technical parameters: Working temperature: 5V; Working voltage: -40~280℃, ±2.5℃; 280~850℃, ±0.9%. Plug type: DCH connector DT04-2P / AMP connector 282104-1
Differential pressure transducer
The differential pressure sensor is installed on the DPF after-treatment system and is used to measure the pressure difference between the exhaust before and after the DPF. The differential pressure sensor transmits the pressure difference signal to the controller. The controller uses the pressure difference signal to detect and determine the degree of DPF particle accumulation, and sends instructions based on the signal to the actuator to achieve the purpose of controlling emissions. Technical parameters: The range of the differential pressure sensor is 0 - 100 Kpa / 0 - 60 Kpa / It can be calibrated. The supply voltage is 5V. The response time is 10ms. The accuracy is initially -40 to 1.
Flanged nozzle
The product is installed on the nozzle seat of the exhaust pipe through a three-hole flange. It is used to measure the amount of urea solution sprayed by the SCR system and has the advantages of high spraying accuracy, good atomization effect, and high stability. Technical parameters: Dynamic flow accuracy: ±5% Static flow: 7.2 kg/h @ 900 kPa Spray cone angle: 23° ± 5° Spray particle size: 75 μm
Urea tank
Product description: This product is used to store the urea water solution for the SCR post-treatment system that meets the national VI emission standards. The material of the urea solution tank is polyethylene, which possesses excellent properties such as high shock resistance, high anti-aging ability, and high corrosion resistance. Inside the tank, there are sensors for urea level, urea quality, and urea temperature. These sensors monitor the state of the urea solution in the tank to ensure the normal supply of the urea solution. This specification urea tank is widely applicable to non-road and on-road Vehicles. Technical parameters Tank material: Polyethylene
Urea pump
This product is a gear-type independent pump. It needs to be installed separately on the entire vehicle using a bracket. It features urea solution filtration, temperature detection, pressure detection, heating, spray pressure building, pressure stabilization, reverse suction, anti-freezing functions, etc. It is small in size and light in weight, making it easy to install and maintain. It is widely used in models such as Class VI light trucks and heavy trucks.
Urea quality level sensor
This product is used to measure the liquid level height, temperature and concentration of the urea solution tank in the SCR post-treatment system. It transmits the corresponding signals to the ECU to ensure the normal operation of the SCR post-treatment system. It has the advantages of high precision, good reliability, strong shock resistance, high thawing efficiency and easy installation. It is widely applicable to road and non-road SCR post-treatment systems. Technical parameters: Working temperature -40 to 85℃; Protection level IP67; Storage temperature -55 to 95℃
Urea injection tube
The pipeline used for the injection and transportation of urea solution in the SCR post-treatment system has excellent properties such as high pressure resistance and corrosion resistance. It is widely applicable to road and non-road SCR post-treatment systems except in cold regions. Technical parameters: Working temperature -40 to 85℃; Pipe diameter φ8 or φ5,The heating type urea suction tube is widely applicable to SCR post-treatment systems used in roads and non-road areas in cold regions. Technical parameters: Working temperature -40 to 85℃; Pipe diameter φ8; Heating power 25 - 40W/m.
