... and subsequently pressure declines with time. The T2P measures the shaft pressure in addition to the tip pressure (Figure 1). At the end of the deployment, the shaft pressure of the T2P is much greater than that of the tip pressure. This is because the shaft has a much larger diameter. As a result, it disturbs...
