A method of measuring pulsating pressures up to 6000 lb/in² by a wire resistance method is described. The pressure sensitive element consists of a cylindrical steel tube with a wire winding, incorporated as an arm in a bridge circuit, the output from which is fed without amplification to a mirror galvanometer with a natural frequency of 10 c/s. The records show that a high degree of linearity and stability can be achieved with this combination.
