In the previous article, we learned about the built-in and external tire pressure detection systems and how to use TPMS, tire pressure monitoring system, tire pressure sensor, etc. Let us look at how to judge the RV tire pressure monitoring system and tire pressure monitoring system sensor that has been purchased.
You can learn all the information you want to know from our previous articles, but you still need to experience the specific product after purchase, because the quality of the product is a probabilistic event, we can not be reliable or evaluated according to the product brand Recommend, don't care about the effect of the product itself. So, the question is coming, what data should we care about most when we go home to ensure that our products are reliable?
The sensitivity to abnormal tire pressure data is an assessment standard with a veto power. If a tire pressure monitoring product fails to detect and warn of abnormal tire pressure in a timely manner, it means that its existence exists.
The abnormal tire pressure data mentioned here is the data that we often say when the tire punctures and leaks. Many products have a data transmission frequency that is too slow. It needs to be monitored at least 6-8 seconds and updated once every 10 minutes, which is lower than this value. Basically, the early warning function of tire pressure monitoring products cannot be played. The display stays for a long time in historical data. The test method is to observe the value change of the display after the vehicle is started. If the value change before and after the start is slow, such products are not recommended to buy. An excellent tire pressure monitoring product can even monitor once every 4 seconds and display data in 2 minutes.
The higher the monitoring frequency and the higher the update frequency, the sooner they can be perceived by the vehicle owner. Some products integrate voice or symbolic representation to directly convert the change in tire pressure value into the final result whether the tire is flat or leaking.
Both internal tire pressure and external tire pressure transmit data wirelessly. The reason for meeting the speed limit requirements is that different products have designed different tire pressure measurement methods, some using cold tire pressure and some using hot tire pressure. What is hot tire pressure? Hot and cold tire pressure mainly depends on whether tire pressure products will update data and parking monitoring data in time. The cold tire pressure is similar to the cold start you mentioned. After long-term parking, the tire pressure displayed at this time is the historical tire pressure. This value does not reflect the tire condition in real time, and can be re-monitored after driving;
The hot tire pressure, and the monitoring data when parking, the real-time data displayed at this time can reflect the condition of the tire. The design idea of some products is to reduce the power consumption as much as possible in order to reduce the use of car chargers, thereby reducing the frequency of data transmission at low speed, or even not transmitting data, or not installing an acceleration sensor, so we cannot at low speed to see the tire pressure data update. Because the accident rate at low speed is low, this is not to cut corners, but only the difference in product ideas.
What other information do you want to know about the tire pressure monitoring system? If you plan to purchase the replicating tpms sensor, tire pressure monitor sensor, tire pressure sensor valve stem, tpms tire pressure monitoring system, please contact our sales consultants and look forward to your inquiry plate.
