Arrangement of a sensor for measuring the temperature of a medium in a motor vehicle
Arrangement of a sensor for measuring the temperature of a medium in a motor vehicle. The sensor has a sensor body and two connecting wires. The first connecting wire and the major part of the sensor body is in direct contact with the medium. The second connecting wire is completely insulated from the medium.
1. A sensor arrangement for measuring a temperature of a medium in a motor vehicle, the arrangement comprising:
a sensor having a sensor body and two connecting wires, including a first connecting wire and a second connecting wire;
said first connecting wire and a majority of said sensor body being disposed in direct contact with the medium and said second connecting wire being completely insulated from the medium.
2. The sensor arrangement according to claim 1 , which comprises a contact holder, and wherein each of said connecting wires is electrically conductively connected to said contact holder by way of a separate connecting contact, wherein a sensor signal is available at said contact holder.
3. The sensor arrangement according to claim 2 , wherein said connecting contacts are formed as a stamped grid or as a flexible conductive foil.
4. The sensor arrangement according to claim 2 , wherein said connecting contacts are formed by an electrical conductor.
5. The sensor arrangement according to claim 2 , wherein a part of said connecting contact of said first connecting wire is disposed in contact with the medium.
6. The sensor arrangement according to claim 2 , wherein said sensor body is disposed in a recess formed in said contact holder and partially surrounded in a sealing manner by an electrically insulating mass to prevent contact with the medium.
7. The sensor arrangement according to claim 1 , wherein said sensor is a resistor having a negative temperature coefficient.
8. The sensor arrangement according to claim 1 , wherein said sensor is a resistor having a positive temperature coefficient.
9. A sensor arrangement for measuring a temperature of a medium in a motor vehicle, the arrangement comprising:
a sensor having a sensor body and two connecting wires, including a first connecting wire and a second connecting wire;
said first connecting wire and a majority of a surface of said sensor body being disposed in direct contact with the medium and said second connecting wire being completely insulated from the medium.
