Bar Graph displays are noted for their ability to very quicklyconvey a relative sense of how much of something is present.They are particularly useful in process monitoring applicationswhere quick communication of a relative value is moreimportant than providing specific data.Designing bar graph pressure gauges based uponsemiconductor pressure sensors is relatively straightforward.The sensors can be interfaced to bar graph display drive IC’s,microcomputers and MC33161 voltage monitors. Designexamples for all three types are included.
