A blast chamber should accurately measure fast pressure dynamics. An explosion creates pressure waves that can fluctuate over as little 0.4 milliseconds, with a magnitude up to 1.2 MPa. a. What is the maximum frequency of the expected pressure signal? b. What is the maximum expected pressure, in each of the pressure units represented in the table below? c. From the options below, which pressure sensor would you choose and why? Sensor A B C D Range -100 to +500 kPa -1 to +20 bar 0 to 2 MPa 0 to 250 psi Accuracy +10 kPa +0.1 bar +0.01 MPa +0.5 psi Max. Frequency 50 kHz 400 Hz 10 kHz 3000 Hz
