Patent ID: 7478561

Claim:
A method for fitting a sensor ( 13 ) in a hydraulic circuit such as an air conditioning circuit, the said circuit comprising at least one rigid pipe ( 1 ) with a fixing and connecting system ( 3 ) at at least one of its two ends, wherein it consists in integrating the sensor ( 13 ) in the fixing and connecting system ( 3 ) without drilling a hole in the rigid pipe ( 1 ) in order to fit the sensor ( 13 ) there, in producing the fixing and connecting system ( 3 ) in the form of a casing ( 5 ) made of plastic which, on the one hand, receives in a fluid-tight manner the end part of the rigid pipe ( 1 ) and, on the other hand, is terminated by a connecting end-piece ( 9 ), in providing in the casing ( 5 ) at least one tapping passage for taking a portion of the fluid conveyed by the rigid pipe ( 1 ) to the chamber ( 11 ) in which the sensor ( 13 ) is housed, and in providing in the casing ( 5 ) a means ( 23 ) for receiving a means of fixing the fixing and connecting system ( 3 ).
