Except for the 1281 Area
Line Meters, the basic planimeter concept is identical to that found
in mechanical instruments. However the measuring wheel is connected
to an electro optical transducer which generates a specific number of
pulses per shaft revolution. These pulses are counted and displayed
(Mod. 44P/C) or counted, scaled and displayed (Models 42P/C , The advantages are numerous. The rather tedious readout and scaling procedure required for mechanical planimeters is reduced to a simple operation and the disadvantages of the limiting 4 digit counting capacity of mechanical instruments is eliminated. Electronic Planimeters provide:
