Tire pressure monitor generally refers to tire pressure monitoring alarm.Unstable tire pressure and temperature can lead to tire blowouts, air leaks and other problems.

This will cause the vehicle to deviate, and front wheel leaks and tire blowouts at high speeds will cause personal hazards.

Real-time monitoring of car tire pressure and installing a tire pressure monitoring alarm on the car can prevent accidents caused by abnormal car tire pressure, adding a safety guarantee for drivers, pedestrians and passing vehicles.

Therefore, tire pressure monitor air tightness testing is an important process related to personal safety.

Item to be tested: Tire pressure monitor

Below, Hirays Technology will show you a case of tire pressure monitor air tightness testing.

The customer requires that the tire pressure monitor can withstand a high pressure of 500Kpa, that is, the tire pressure monitor IP68 waterproof level test:

Equipment used: HC classic series air tightness detector

Testing method: Use the method of direct testing of finished products. Since the shape of the tire pressure monitor product does not have holes that can be directly inflated, a customized mold is required so that the product is in a closed cavity during testing.

Tire pressure monitoring air tightness testing mold

Place the tire pressure monitor into the mold and test it.The test pressure is 500kpa, and the maximum allowable leakage is 0.09kpa. The air intake time is 10s, the pressure stabilization time is 10s, the test time is 5s, and the quantitative air intake is 3s.

The Classic series is a very mature and stable instrument from Hirays.Extra large measuring range is optional.

With its high precision and stability, more than 20,000 sets of equipment have been deployed in more than 5,000 customer factories.

The functions and performance parameters of the instrument can meet the needs of most customers while also taking into account the cost performance.
