A fast pressure gauge based on a SMD (Surface Mounted Device) resistor sensor technique was developed at the Ernst-Mach-Institut to measure shock and pressure waves. The SMD gauge permits the recording of rise times up to tr 1 s and maximum pressures up to 300 MPa. The primary incentive of this development was to enable measurements during an explosion inside a shelter or closed room. Sample results of such measurements are presented.
