This unfired bricks moisture detector circuit is composed of detection input circuit and LED display circuit, it is shown in the figure 8-77. The detection input circuit iscomposed of detector probe, operation amplifier integrated cirucit IC1(N1, N2), resistors R1-R8 and water content measurement area selection switch S1. LED display circuit consists of LED linear analogue display drive integrated circuit IC2, LED VL1-VL10 and point/line display selection switch S2. S1 has three shifts, 1 shift tests 13% water content area, 2 shift tests 14% water content area, 3 shift tests 15% water content area.
