What is a tire pressure sensor?

A Tire Pressure Monitoring System (TPMS) is an electronic device designed to monitor the pressure inside a tire. Normally, 1 car tire pressure sensor will have 4 sensors installed in 4 tires and 1 display screen .

On the display screen, there will be full information about the pressure and temperature of each tire . When the pressure in the tire changes suddenly or is higher/lower than the preset level, the sensor will notify the driver through audio and visual signals.

Based on the installation location, people divide tire pressure sensors into two main types: internal tire pressure sensors and external tire pressure sensors.

• Internal Tire Pressure Sensor : A type with a sensor head mounted inside the tire, the sensor valve replaces the valve of the original tire.
• External tire pressure sensor : A type with a sensor head attached to the valve head of the wheel.

Benefits of installing a tire pressure sensor:

Limit traffic accidents, ensure the safety of car users

The pressure inside the wheel is an extremely important factor that drivers need to monitor regularly. If the pressure is not guaranteed, the wheel will be too soft (underinflated, underinflated) or too tight. In this case, the wheel can explode and cause an accident at any time.

In addition, improper pressure also affects the performance and stability of the vehicle, increases fuel consumption and makes the driver feel uninterested.

The best way to monitor car tire pressure is to use a tire pressure sensor. With this device, you can monitor the pressure inside the wheel regularly, detect abnormalities in time , and make appropriate adjustments (for example, deflate when the wheel is too tight, inflate the car tire when it is too tight). the cake is too young), thereby limiting the risk of accidents.

Helps prolong the life of tires

Wheels that are too tight or too young not only cause safety problems, but also reduce the life of the tire, making it easy to crack, wear, and deform. By using a tire pressure sensor, you can limit these conditions, help the tire last longer, thereby saving repair costs.

Maximize fuel economy

When your car is not equipped with a tire pressure sensor, when the tire is inflated too high or the tire is too low, the tire pressure is low, inadvertently increasing the friction on the road surface, leading to a situation that leads to more fuel consumption. more material.

On the contrary, when you install a tire pressure sensor in your car, it will help you monitor and keep the tire pressure in a standard condition, so it can save 2 to 3% gas compared to under-inflated tires.

Internal tire pressure sensor

An internal valve tire pressure sensor is a device with a sensor head attached to the inside of the tire, instead of the original tire valve.

Advantage:

• The sensor device is mounted inside the tire, so it is safe, without worrying about being stolen during use.
• Preserve the original aesthetic of the car.
• The valve can be replaced when it is damaged or the battery runs out.
• Tires can be rotated without removing the sensor valve.

Defect:

• Because the sensor device is located inside the tire, the installation operation is relatively complicated, it is necessary to remove the tire and balance it dynamically. So when installing the internal valve sensor, the user needs to bring the car to the center to ensure the correct process.
• Specialized tools and highly skilled workers are required.

External tire pressure sensor

External valve tire pressure sensor is a device with a sensor head mounted on the outside of the car valve.

Advantage:

• Installation is quick and easy, no need to remove the tire. Users can install it themselves at home.
• Replaceable when sensor valve is damaged.
• Does not affect the aesthetics of the vehicle.

Defect:

• A professional sensor valve opener is required for every car pump.
• The valve is installed outside, so it can be stolen. However, today’s external valve tire pressure sensors are all designed with anti-theft valves, so this case is very unlikely.

Should you buy an internal or external tire pressure sensor?

	Internal tire pressure sensor	External tire pressure sensor
Advantage	Long battery life: 3 to 5 years on average. Although the installation is a bit difficult, it is convenient for inflating the car later, without losing time. High durability due to not being exposed to the environment, not affected by external agents. Ensure high accuracy parameters. During use, if any sensor valve is damaged, it can be easily replaced.	Easy to control and keep tire pressure at standard level. In the process of driving with standard tire pressure will help the driver save fuel and save a lot of money. The tire pressure sensor mounted on the outside of the valve will help us avoid abnormal wear on the vehicle’s components.
Defect	The installation operation is relatively complicated, it is necessary to remove the tires and dynamic balance. So when installing, the user needs to bring the car to the center.	A professional sensor valve opener is required for every car pump. The valve is installed outside, so it can be stolen.

From the above analysis, it can be seen that each type of tire pressure sensor has its own advantages and disadvantages. So, depending on your preferences and needs, you can choose the right product.
