Transient thermal loads on piezoelectric pressure sensors as a result of an explosion lead to a heat flux which results in a reduction of the measured pressure amplitude as well as an increase of the scatter of the measurement results. The effects of this so-called thermal shock depend on the type of sensor and can be reduced by suitable measures, e.g. thermal protection layers of RTV (Room-Temperature-Vulcanizing) silicone.
