The Shock Tube Pressure Transducer: A description of the pressure transducer used in the shock tube at Northampton College

SHOCK tube measurement techniques require the use of instrumentation capable of sensing pressure variation across passing strong shock waves. The speed of shock wave passage along the shock tube is of the order of 6,000 to 7,000 ft./sec. while shock thickness is of the order of 0·1 in. This is calculated from the equation:—
