Digital Display Aerial Survey Meter

摘要

Three Digital Display Indicators have been incorporated into the CD V-781 Aerial Survey Meter replacing the three conventional panel meters to display dose rate readings numerically. The Digital Display Indicator contains a D'Arsonval mechanism and an optical system so arranged to provide a projected image on a screen. Readability error is virtually eliminated since only one indicator is visable at a time displaying a discrete reading of dose rate. Each Digital Display Indicator provides 10 distinct values in a two figure display measuring 3/4 inch high by 1/4 inch wide. (Author)
