Tire pressure control retrofit kit
for vehicles without active tire pressure monitoring system TPMS with a recommended tire pressure of the car manufacturer up to approx. 2.5 BARThe set consists of:
- 1 operating and display unit
- 4 tire pressure sensors with metal valve
- 1 USB charging cable
- 1 adhesive pad for fastening
- 1 instruction manual
The system can also be installed in a passive system, so that in addition to the tire pressure loss warning, a real tire pressure control can be achieved. This means that you always have the pressure and temperature of your tires in view and can therefore detect irregularities and problems long before a warning appears and rectify them in good time before major and more expensive damage occurs.
The control unit can either be charged using the included USB charging cable or charged and supplied with power using the solar panel built into the top. In normal operation, the solar panel is sufficient. The device switches off within a few minutes after the vehicle is parked, so that the energy consumption is optimal. When the vehicle is started, the device is automatically switched on by a motion sensor system so that it cannot be forgotten. The switch-on function can be deactivated and reactivated if necessary.
We deliberately only offer a version with internal sensors, because a solution with sensors in the valve caps only works if the valve is permanently actuated and thus only the seal in the cap keeps the pressure in the tire, which in our opinion is a high risk. In addition, the weight of these caps causes the valve to generate a large centrifugal force on the valve at high wheel speeds, which can be harmful in the long run. The slightly higher effort required for the installation of an internal sensor system means a real safety gain. In addition, the sensors are also safe from theft and not exposed to external influences such as road dirt and salt.Technical data:
