Pressure measuring device, tap, storage unit and installation comprising such a device

A pressure measuring device for measuring the pressure of a gas, comprising;

• a connector extending along a longitudinal direction around a central longitudinal axis, the connector comprising a first longitudinal end configured to be fixed to an element containing pressurized gas, and a second longitudinal end provided with a diaphragm configured to be subjected to the pressure, the diaphragm comprising a pressure sensor of the piezoelectric type generating an electrical signal representative of the pressure measured, said pressure sensor being connected to an electronics board comprising electronic logic for processing the electrical signal of the sensor, and
• a transmission/reception antenna of the radiofrequency type fitted on said electronics board in order to receive and transmit data from and to the electronic logic, the electronics board being housed in a protective casing fixed to the connector, wherein the antenna is located on or adjacent to an axis passing through the central longitudinal axis of the connector, at a distance of between zero and five millimetres from an axis passing through the central longitudinal axis of the connector, and in that the antenna is located level with the border of a first end of the electronics board, adjacent to a wall forming a base of the casing.
