What is the typical pressure output of a fully stimulated 3-15 psi instrument?

A fully stimulated 3-15 psi instrument is designed to provide a pressure output that correlates with the parameters it measures. The specified range of 3-15 psi indicates that the instrument will output 3 psi at its lowest input signal and up to 15 psi at its highest input signal. When fully stimulated, or at maximum input, the instrument reaches the upper limit of its range, which is 15 psi. This reflects the maximum output pressure that the instrument can provide under full excitation or input. Thus, the choice indicating 15 psi is the correct interpretation of how a 3-15 psi instrument operates at full scale.
