In a basic diagram of his scheme, there is a battery for the current and four leads, as shown in Figure 1. On the left is a battery, and below are four leads. Current from the battery reaches the resistor X via the two outer leads, while the inner leads are for the independent voltage-measured circuit.
Current sensing is used to perform two essential circuit functions. First, it is used to measure "how much" current is flowing in a circuit, which may be used for power management in a DC/DC power supply to determine essential peripheral loads to
The diaphragm and bellows are two other basic sensing mechanisms employed in aircraft instruments for pressure measurement. The diaphragm is a hollow, thin-walled metal disk, usually corrugated. When pressure is introduced through an opening on one side of the disk, the entire disk expands.
