A sensor arrangement (1) for measuring a pressure and a temperature in a fluid is disclosed. The sensor arrangement (1) comprises a temperature sensitive electrical element (3) and a pressure sensing electrical element (6), the temperature sensitive electrical element (3) and pressure sensing electrical element (6) are both coupled to one side of a metallic membrane structure (4,16). The metallic membrane structure is arranged to pass on the temperature of the fluid which is at the other side of the membrane structure (4,16) to the temperature sensitive electrical element (3) and to pass on the pressure in the fluid to the pressure sensing electrical element (6). In this way a combined pressure and temperature sensor is obtained which is applicable in vehicle air-conditioning systems working with CO2 as refrigerant.

The invention claimed is: 1. A sensor arrangement (1) for measuring a pressure and a temperature in a fluid, the sensor arrangement (1) comprising a common body (11, 12, 14), a membrane structure (4, 16), a temperature sensitive electrical element (3) and a pressure sensing electrical element (6),
The invention claimed is: 1. A sensor arrangement (1) for measuring a pressure and a temperature in a fluid, the sensor arrangement (1) comprising a common body (11, 12, 14), a membrane structure (4, 16), a temperature sensitive electrical element (3) and a pressure sensing electrical element (6), the temperature sensitive electrical element (3) and pressure sensing electrical element (6) are both coupled to one side of the membrane structure (4, 16), wherein the membrane structure (4, 16) comprises an elongated body (16), at a closed end (15) of the elongated body is located the temperature sensitive electrical element (3) and close to an open end (17) is located the pressure sensing electrical element (6). wherein an axial movement of the elongated body (16) influences an electrical property of the pressure sensing electrical element (6). 2. A sensor arrangement according to claim 1, wherein the membrane structure (4, 16) includes a pressure sensitive structure (4) and the pressure sensing electrical element (6) is mounted on the pressure sensitive structure (4). 3. A sensor arrangement according to claim 2, wherein the pressure sensitive structure (4) comprises an inner part (31) and an outer part (32), wherein a pressure acting on a membrane structure (4, 16) will axially move the inner part (31) with respect to the outer part (32) of the pressure sensitive structure (4). 4. A sensor arrangement according to claim 2, wherein the pressure sensitive structure (4) is circular and comprises a hole (7) in the centre, and the open end (17) of elongated body (16) is hermetically connected to the pressure sensitive structure (4) to seal the hole (7). 5. A sensor arrangement according to claim 4, wherein the arrangement comprises at least two pressure sensing electrical elements (6), wherein the at least two pressure sensing electrical elements (6) be symmetrically divided around the hole (7) of the pressure sensitive structure (4). 6. A sensor arrangement according to claim 1, wherein the temperature sensitive electrical element (3) is coupled to the membrane structure 4,16) by means of a thermal conductive compound (26). 7. A sensor arrangement according to claim 1, wherein a first part (14) of a common body (11, 12, 14) surrounds lengthwise at least partially the elongated body (16) of the membrane structure (4, 16). 8. A sensor arrangement according to claim 7, wherein the sensor arrangement further comprises a sealing member (5), the sealing member (5) being present between the first part (14) of the common body (11, 12, 14) and the elongated body (16). 9. A sensor arrangement according to claim 1 wherein the membrane structure (4, 16) has a coaxial structure. 10. A sensor arrangement according to claim 1 wherein the fluid is a gas. 11. A sensor arrangement according to claim 1 wherein the fluid is a CO2-stream.
