Abstract: The world is dynamic, not static. And so is the field of measurement. Dynamic quantities need to be measured with sensors that are characterized for and calibrated with dynamic loads. In this volume of PTB Mitteilungen the focus is on dynamic measurements of pressure (ambient to 400 MPa) and temperature (ambient to 3000 °C) with temporal resolution of milliseconds or faster. This is an important range for applications, for instance the optimization of internal combustion engines (that continue to be with us for some time to come, running on different types of fuel), control of industrial processes, and safety testing.

Currently, however, sensors for pressure and temperature can be calibrated only with static loads, not on the time scales of milliseconds required by many applications. At those faster time scales, sensors are known to exhibit dynamic responses different from the static ones. Therefore, calibration facilities for truly dynamic calibration of pressure and temperature sensors are needed.

In particular, the question of traceability of such dynamic pressures and temperatures must be addressed.
