Abstract
A device for monitoring the sealing properties of a gas-filled chamber is provided. The temperature-sensitive device is formed out of a thermally-reacting element (14, 19, 20, 24). The element changes its dimensional length depending on a temperature change. The element (14, 19, 20, 24) is disposed between a pressure measurement device (6, 11) and a valve (7, 8; 9, 10), serving as a signal generator. The device can be used for a monitoring of the pressure in a vehicle tire or of the gas density in a vehicle tire.
