A GAUGE FOR MEASURING IMPULSIVE PRESSURE IN A CONTAINER SUBJECTED TO LARGE, TIME-VARYING APPLIED VOLTAGES.
AEROSPACE CORP EL SEGUNDO CA LAB OPERATIONS
A pressure gauge consisting of a strain gauge transducer, bridge, and decoupler is described for the measurement of time-varying pressures in the presence of an electrical noise environment typical of capacitor discharge systems. In particular, the transducer of the gauge has been subjected to large, time-varying applied voltages and large, time-varying magnetic fields with no ill effect on the output of the gauge. At least an order of magnitude increase in these quantities i.e., Vmax, etc. is believed possible without serious effect on the gauge output. The gauge can be statically calibrated, has a risetime of 4 sec, and can be compensated for electronic drift.
