The main material of the urea liquid level sensor is reinforced nylon and stainless steel. The installation method adopts tooth-shaped bayonet screwing in, which is easy to assemble and disassemble; the wiring adopts imported APM connectors, which is fast; the detection liquid level adopts the principle of electromagnetic induction, with stable signal output and high precision , The detection depth can be customized according to user requirements; the product structure is simple and reliable, only the float is a moving part, and the service life is long.
The sensor uses the magnetic field generated by the float to control the on-off of the reed switch in the measuring conduit, converts the change of the measured liquid level into a resistance voltage signal output, and then connects with the secondary instrument to achieve the purpose of detecting the liquid level in the urea tank and giving an alarm . Purpose. Compared with other types of liquid level measurement technology, no complex circuit is required, the implementation is simple, the cost is low, and the reliability is high.
The urea liquid level sensor has multiple functions such as liquid level detection/alarm, temperature detection/alarm, engine cooling water circulation heating, urea filtration, and urea suction.
In order to reduce the emission concentration of pollutants in the exhaust of diesel vehicles, selective catalytic reduction (SCR) technology is used for exhaust emissions of diesel vehicles, and urea solution is used to treat nitrogen oxides (NOX) in the exhaust, and the method of reducing NOX emissions meets the national requirements . IV Emissions regulations limit soot and NOX.
The urea liquid level sensor is designed for the SCR system and is used for the detection of the urea liquid level of the SCR exhaust gas treatment system of the diesel engine vehicle.
