A method for fitting a sensor in a hydraulic circuit utilizes at least one rigid pipe with a fixing and connecting system at least one of its two ends, wherein the pipe integrates the sensor in the fixing and connecting system without drilling a hole in the pipe in order to fit the sensor. The fixing and connecting system has a casing made of plastic which, on the one hand, receives in a fluid-tight manner the end part of the rigid pipe and, on the other hand, is terminated by a connecting end-piece. The casing has at least one tapping passage for taking a portion of the fluid conveyed by the rigid pipe to a chamber in which the sensor is housed. The casing has an aperture for fixing the fixing and connecting system.
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).
A rigid pipe for a hydraulic circuit, in particular for an air conditioning circuit of a motor vehicle, comprising a fixing and connecting system (3) at one of its ends, and which is provided with a pressure or temperature sensor (13), wherein the sensor (13) is integrated in the fixing and connecting system (3) and wherein the fixing and connecting system (3) consists of a casing (5) which receives in a fluid-tight manner the end part of the rigid pipe (1), which is terminated by a connecting end-piece (9) and which has at least one tapping passage to take a portion of the fluid conveyed by the rigid pipe (1) to a housing or chamber (11) of the casing (5) in which the sensor (13) is housed and which has a means (23) for receiving a means of fixing the fixing and connecting system (3).
