Different models of urea sensors can be customized

Product description

The selective catalytic reduction (SCR) method uses urea injection system to inject urea aqueous solution into the exhaust gas system. In the exhaust stream, the urea solution breaks down into ammonia, which reacts with nitrogen oxides in the presence of a catalyst to convert harmless nitrogen and water. Urea pressure sensor is used to monitor urea injection pump, ensuring the amount of urea injection is the key to the whole selective catalytic reduction process. In the process of automobile exhaust treatment, the on-board urea control module calculates the precise urea injection amount under various engine conditions, as well as the urea mixed air volume in the on-board compressed air system. Then the urea pressure sensor is used to monitor the injection pressure to control and regulate the flow of urea, so that it is injected into the emission treatment system in the form of atomization, through the catalyst and tail gas mixing, complete the catalytic reduction reaction. The control of pressure sensor directly determines the amount of urea injection, and the amount of urea injection will further affect the catalytic reduction effect, which plays a crucial role in the purification of waste gas. Specializing in the production of high-precision pressure sensors, engineering machinery pressure transmitter, gas pressure difference sensor, intake manifold absolute pressure transmitter, wall mounted furnace pressure sensor, water pump pressure sensor, vacuum pressure sensor, etc.
