The electronic truck scale sensor single chip microcomputer is an integrated circuit chip, which adopts VLSI technology to process the central processing unit CPU random access RAM, read only memory ROM, various I/O ports and interrupt systems with data processing capability, timing. A small and complete computer system, such as a timer/timer (which may also include a display driver circuit, a pulse width modulation circuit, an A/D converter, etc.), is integrated into a silicon chip. The PN junction, said two PN transistors into a triode, and then an amplifier circuit composed of three poles of the triode, and then a distortion-introducing amplifier circuit, and then a multi-stage amplifier circuit composed of a plurality of amplifier circuits. And continue to say that there is zero drift phenomenon, the differential amplifier circuit is inserted into the resistance symmetry, and finally the resistance is difficult to be symmetrical. Learning the long tail differential amplifier circuit connection encounters a thorny problem: the bulb's flashing circuit is connected in two Under the time relay operation, the electrical relay has a normal delay of 0.2 seconds or more at each time, but if it is Or when the delay time is less than 0.2 seconds, the circuit is short-circuited. The electric valve trips the rectifier bridge to seal the rectifier tube in a shell. It is divided into full bridge and half bridge. The full bridge is the four bridge rectifier circuits that will be connected. The diodes are sealed together. The half bridge seals half of the two diode bridge rectifiers, and two half bridges form a bridge rectifier circuit. One half bridge can also form a full-wave rectifier circuit with a center tap of the transformer. The weighbridge sensor selects the rectifier bridge to take into account the rectifier circuit and operating voltage.
