Remarks: 1. The external tire pressure monitoring is screwed on the valve, and the tire pressure is monitored by blocking the valve needle. Plus the owner's tires are not made.
Dynamic balance will cause air leakage after a long time, and the tire will be in an unbalanced state for a long time, which will cause great tire wear and fuel consumption.
The child is harmful and useless, but it is dangerous to use. It is forbidden to use external tire pressure warehouse. 2. External tire pressure monitoring TPMS, the sensor outside the valve is more dangerous, and it is impossible to correctly understand the internal situation of the tire, even if the car is driving.
Without the opportunity of factory testing, the external gas nozzle may be destroyed by human and material resources at any time. 3. The sensor with an external air valve (external) is more dangerous, and it is impossible to correctly understand the internal situation of the tire, and there is even a chance of being detected by the car factory.
Neither, because it can only detect the tire pressure and temperature in the valve, so it is called "adult toy" in the special report of Tire Review in the United States.
The outside of the air valve may be damaged by manpower and material resources at any time. 4. Please pay attention to other counterfeit products: the monitor cannot be clearly displayed day and night. There are also some fake TPMS batteries that have a high position on monitors and cars.
There is a danger of explosion at low temperature, which causes drivers to pay attention to whether there is electricity when the battery is running out every day. 5. Please pay attention to other fake TPMS: the integrated sensor will be damaged soon. Under normal circumstances, the warranty period of power collection of TPMS sensors can reach 7 years.
However, the valve gasket of this design may only have a life of one year and cannot be updated, and it is only equipped with an acceleration switch when the speed exceeds 25 kilometers per hour.
Another way to improve the management of bad power supply is to start the sensor only when it is turned on (when the car is started, the tire is at rest).
When the car starts, the tire pressure/temperature information is still unknown, and the sensor detection interval is too long, exceeding 6 seconds/cycle (the response speed is too slow).
When the tire deflates a lot, it takes 50 seconds to know (the reaction time is too long and dangerous). 6. Please note that there is no national certification or fake certification for other counterfeit TPMS, and it has never passed the factory certification or performance. The development process is completely non-automobile.
The process and strict planning certification required by the factory are only sold in the after-sales market, and there is no formal test specification of the factory, which has not passed the requirements of the factory.
Various tests and verifications required. The product has no verification data and cannot enter the international racing level.
Authentic TPMS safety requirements: 1, designated for international racing (professional racing level); 2. Through automobile factories all over the world
Durability test (factory specification); 3. Have national communication certification; 4, in line with national environmental standards; 5. TPMS of global automotive electronic parts
First place in the competition; 6. Mass production of bus (long-distance) wireless tire pressure monitoring system; 7. 100% automatic testing equipment, 100% supervision.
Control equipment; 8. The Apple software of the American Apple Computer has been certified and downloaded and used on the Apple website; 9. The world media are scrambling to report; 10、
This product has patent certification.
