N2 - Carbon com position resistor (CCR) gauges were evaluated with two shock tubes at the University of Illinois, Urbana/Cham paign (UIUC). The shock tubes create step pulses, pressures that rise abruptly to steady values. In one test series, a CCR gauge mounted on the side of the shock tube sensed the passing step pulse. In the other series, a pair of CCR g au g es m ounted side-by-side at the e n d of th e sh ock tub e sen sed the step pulse as it reflected from the endwall. The testing demonstrated an average rise time of 6 μs for the CCR gauges, corresponding to a frequency response conservatively estimated to be 50 kHz. The rugged, low-cost CCR gauges dynamically measure pressures as small as a few bars and as great as two kilobars. They are also insensitive to static and electromagnetic emissions. Combined with the 50 kHz frequency response, CCR gauges are ideal for multichannel, dynamic measurement of blast.
