Match the following pressure-measuring devices with the correct name. The device names are: barometer, Bourdon gage, piezometer, manometer, and pressure transducer.

a. A U-shaped tube in which changes in pressure cause changes in relative elevation of a liquid that is usually denser than the fluid in the system measured; can be used to measure vacuum.

b. Typically contains a diaphragm, a strain gage, and conversion to an electric signal.

c. A round face with a scale to measure needle deflection, in which the needle is deflected by changes in extension of a coiled hollow tube.

d. A vertical tube in which a liquid rises in response to a positive gage pressure.

e. An instrument used to measure atmospheric pressure; can be of various designs.
