Introduction You are asked to help prepare an invasive arterial blood pressure system for a patient undergoing a laparotomy. Invasive measurement of arterial blood pressure is an example of dynamic...
The ‘input’ (x) or physical quantity being measured, changes over time (t) and is therefore said to be ‘unsteady’ The output (y), as a function of time y(t) and can generally be given as a factor (K) of the input as a function of...
Speed of Response Settling Time Rise Time Overshoot Measurement Lag Fidelity Dynamic Error The rapidity with which a measurement system responds to changes in the measured quantity. The time required by instrument or system to settle to its final steady position after...
Measurement systems respond differently to inputs due to their inherent properties such as resistance, capacitance, mass and dead time. The dynamic response of an instrument is typically described as either zero, first, or second-order: The order of an ideal dynamic...
