显示仪(二次表)显示仪是变送器的数字显示单元,变送器编码机构送来的4组共15个编码讯号;A、B、C、D、E、F、G、H、I、L、M、N,O、X、Y,经过各自的鉴别器分解为;A_1、A_2,B_1、B_2,C_1、C_2,D_1、D_2,E_1、E_2,F_1、F_2,G_1、G_2,H_1、H_2,I_1、I_2,L_1、L_2,M_1、M_2,N_1、N_2,O_1、O_2,X_1、X_2,Y_1、Y_2(其中:A_1、B_1、C_1、D_1、E_1、F_1、G_1、H_1、I_1、L_1、M_1,N_1、O_1、X_1、Y_1、代表逻辑“非”)两种讯号,分别送到各位译码器,根据译码表和给定的逻辑条件译成甘应于液面高度的十进制数,通过驱灯显示电路显示出来;图12是显示仪的外形。面板上共显示6位数字;右4位为液面高度值,依次
Display instrument (secondary table) display is the transmitter of the digital display unit, the transmitter coding mechanism to send a total of 4 groups of 15 encoded signals; A, B, C, D, E, F, A, A_2, B_1, B_2, C_1, C_2, D_1, D_2, E_1, E_2, F_1, F_2, G_1, G_2, H_1, H_2, I_1, I_2, L_1, L_2, M_1, M_2, N_1, N_2, O_1, O_2, X_1, X_2, Y_1, Y_2 I_1, L_1, M_1, N_1, O_1, X_1, Y_1, representing the logic of “non”) two kinds of signals, respectively, to the decoder, according to the decoding table and given the logical conditions into Gan should be liquid Surface height of the decimal number, through the drive light display circuit is displayed; Figure 12 is the appearance of the display. The panel displays a total of 6 digits; the right 4 digits for the liquid level value, followed by
