Sensor for measuring the pressure and temperature of tires
First Claim
1. A sensor for determining pressure and temperature of air in a vehicle tire, said sensor comprising a housing to be secured in an aperture in a tire rim and having an opening communicating with a tire interior;
- a pressure sensor element within said housing;
at least one temperature sensor element arranged in said opening;
an insulating foil for monitoring a mass of a tire inflating gas, said insulating foil being arranged in said opening and being surrounded by the tire inflating gas, said at least one temperature sensor element being arranged on said insulating foil; and
means for thermally insulating said insulating foil from said housing.

Abstract
A sensor for determining the pressure and temperature of the air in a vehicle tire and comprising temperature sensor elements decoupled from the temperature of the wheel rim and coupled to the temperature of the tire air. The temperature sensor elements are arranged on an insulating foil which is stretched over one of the openings of a cover cap which is fastened at the sensor housing so as to be thermally insulated. The temperature sensor elements are connected with connecting leads of the electronic circuit of the sensor via conductor paths of the insulating foil.
