Abstract : The bandwidth of the current measurement chains is often limited for air pressure measurement in the context of detonics. Furthermore, the transmission of the measurement signal in an extreme environment via cables of several tens of meters can reduce the reliability of the measurement while limiting the bandwidth. A theoretical analysis of the measurement chain is implemented in order to understand the influence of the bandwidth on the signal to be measured and the different elements limiting the bandwidth. A wireless transmission of the measurement signal is developed to transmit transient regimes in a fireball during an explosion. This solution is fully described and positioned in the state of the art. It makes it possible to measure rise times of the order of one hundred nanoseconds.
