摘要:
The invention relates to a method for manufacturing a temperature sensor with a thermocouple, which includes the following consecutive steps: a) manufacturing a cable with mineral insulator (14) including two thermocouple wires (10, 12) extending along the entire length of the cable with mineral insulator and embedded in a mineral insulator (8); b) stripping one of the ends of the cable with mineral insulator over a length of 2 to 20 mm, preferably less than 15 mm, preferably less than 10 mm, such as to expose the ends of the thermocouple wires; c) connecting the ends (40, 42) of the thermocouple wires thus exposed, such as to constitute a thermocouple hot spot (13); and d) attaching a cap (20) to said cable with mineral insulator so as to protect said hot spot.

The invention relates to a device for measuring differential pressure, comprising a first pressure measurement means (11) which measures a first pressure value (P1) and a second pressure measurement means (12) which measures a second pressure value (P2), the second pressure measurement means (12) being configured to read the pressure (P1) measured by the first measurement means (11), to calculate the pressure difference between the pressure (P1) measured by the first pressure measurement means (11) and the pressure (P2) measured by the second pressure measurement means (12), and to transmit the pressure difference value in the form of a single signal. The first pressure measurement means (11) is of the analogue or digital type, the second pressure measurement means (12) is of the digital type, and the transmitted differential pressure value is in the form of a single digital signal.

The invention relates to a differential pressure device including: a pressure sensor comprising a substrate (14) supporting a pressure measurement member (10) provided with a membrane (16) having opposite first and second surfaces, the pressure sensor being configured to emit an electrical signal on the basis of a difference between the first and second pressures exerted on said first and second surfaces, respectively; and a housing (5) defining a cavity (12) in which said pressure sensor is arranged. Said cavity is partially filled with a resin (50) such that said resin covers said substrate without being in contact with said membrane.

The present invention relates to an assembly (1) for a combustion engine (10) comprising an electric compressor (5) and an air intake system, the air intake system comprising a double manifold (2) at the inlet to which there is a valve (4) configured to allow the intake gases to circulate in the manifold (2) and/or to allow the intake gases to bypass the electric compressor (5). The double manifold (2) comprises a swirl manifold (22) and a filling manifold (21), fed by two independent inlets, which can be closed off by the valve (4) independently of one another.
