Abstract: 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.

Abstract: A junction element for a hydraulic fluid circuit, comprising a body (1) which is provided with inner channels (2,3) leading in an outer direction through a plurality of connection elements (7,8,9,10) which can cooperate with outer channels and with the support (12) of at least one sensor (13) for the value of a physical parameter of the fluid circulating in one of the inner channels (2,3) of the body.

Abstract: The invention relates to a position or displacement sensor comprising a detection circuit and a rider (2), the position of which is detected by the detection circuit, this rider (2) comprising a support (20) consisting of a material inert to the detection circuit, and an influencing member (21) carried by the support (20) and comprising a material that is active to the detection circuit. The influencing member (21) is produced in the form of particles (P) of the active material which are embedded in a mass (M) of the inert material to measurement of the displacement or position of a motor vehicle braking system piston.

Abstract: A pneumatic servobrake having a detector (13) for the measurement of the pressure in a front chamber (1). The detector (13) has a baseplate (14) that is situated opposite an opening (25) in a wall (26) of the front chamber (1). A yoke-forming cage (38) that is placed over the opening (25) has an opening (40) that is traversed by a pressure sampling tube (16). The tube has a collar (41) that is retained between the cage (38) and the baseplate (14). An adapter (23) connected to the wall (26) urges the tube (16) against the cage (38) to allow for both a sideways motion (20) and a tilting motion (21). The lower part (31) of the tube (16) is fitted with an O ring (33) to establish a sealed pneumatic connection between the tube (16) and baseplate (14) such that a first sensor (15) is isolated from a second sensor (48) in a measurement of pressure in the first chamber (1).
