Abstract
The invention relates to an electronic pressure gauge for measuring the pressure inside a container, particularly a pressurized gas cylinder, said pressure gauge including: at least one pressure sensor; an electronic unit designed to acquire, store and process data; and at least one information device capable of transmitting at least one item of information. The pressure gauge also includes a first radio with a reception port, said first radio being connected to the electronic unit so as to receive external data in order to modify the operation or the configuration of the pressure gauge. The reception port of the first radio is designed to read data modulated in terms of the frequency and/or intensity of an external magnetic field at a first low frequency, for example a frequency between 50 and 300 khz.
