ABSTRACT:
Apparatus for displaying pressure in digital form including a plurality of pressure-sensitive transducers arranged in a vertical linear array within a liquid container, from a most sensitive position to a least sensitive position. Electronic matrix means responsive to actuation of the transducers provide an output signal indicative of the least sensitively positioned transducer that has been actuated. A digital display device is coupled to the output of the electronic matrix means and is responsive to the output signal, for displaying in digital form the pressure in the container.
