Are external TPMs reliable?

THERE ARE TWO TYPES OF SENSORS: EXTERNAL & INTERNAL SENSORS

WHY NO EXTERNAL VALVE CAP SENSOR?WHY AN INTERNAL SENSOR?

Nowadays, the external valve cap sensor is the most common. The advantage is the ease of installation, but there are also various disadvantages.

1. The external valve cap sensor is initially attached to the outside and is capable of TIRE TEMPERATURE NOT to measure accurately.
2. External sensors are attached outside the wheel. In principle, they should not be attached to the wheels of the drive axle, as they are located outside the wheel and can be easily damaged.
3. Since the sensor is placed outside the wheel, it can easily be broken off or stolen. Experience has shown that you need several valves for the period of use of a TPMS set. That means additional costs.

4. Degrades the valve and leads to decreased valve performance. Not recommended for reliable tire monitoring.
5. Most valve cap sensors must be removed when inflating the tire. To prevent theft, valve cap sensors have different anti-theft devices.

The installation is certainly more complex, but you don't have to worry about it afterwards. That compensates for the additional effort at the beginning.

1. The sensor is located where the air pressure and air temperature are measured - INSIDE. This is the only way to measure reliable and accurate values.
2. Internal sensors are located inside the tire - this is good for ALL tires.
3. The sensor is not stolen, it is not broken off and lasts for the entire product cycle (5-7 years).



4. No impairment of the valve stem
5. Trouble-free tire inflation possible
