A fast pressure gauge based on a SMD (Surface Mounted Device) resistor sens
or 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 t(r
) congruent to 1 mu s and maximum pressures up to 300 MPa. The primary ince
ntive of this development was to enable measurements during an explosion in
side a shelter or closed room. Sample results of such measurements are pres
ented.
