Tire pressure sensor is installed on each wheel and works until the battery is completely discharged. A sophisticated device combines sensors that measure and control temperature and pressure with electronic elements. The mechanism includes an antenna that transmits impulses from sensors to the control unit.

The principle of the tire pressure sensor work

Each HELLA brand Wheel Sensor, tyre pressure control system is registered in the receiving device, which has a separate display for displaying information. Every 1-2 minutes, the display is updated with information received from all four sensors. This allows you to control the amount of air in each wheel. Having a non-standard TPMS system, it is convenient to level this parameter after tire fitting. Sensors screwed onto the outside of the valve are no less popular. It is easier to install such devices, since disassembly of the wheel is not required. They transmit information via the Bluetooth channel, and therefore it is possible to monitor the air in the tires even using a regular smartphone.
