The electrical apparatus works normally when the delay of each time relay is more than 0.2s, but if one or both of them is less than 0.2s, the circuit is short circuited, Recommended electronic weighbridge The rectifier bridge tripped by the electric valve is to seal the rectifier tube in a shell, which is divided into full bridge and half bridge. The full bridge is to seal the four diodes of the connected bridge rectifier circuit of the weighbridge together. The half bridge is to seal half of the two bridge rectifier diodes of the weighbridge together. The two half bridges can form a bridge rectifier circuit of the weighbridge, and the one half bridge can also form a full wave rectifier circuit of the transformer with a central tap, Electronic weighbridge manufacturer Rectification circuit and working voltage shall be considered when selecting rectifier bridge for weighbridge sensor. When there is high resistance in the wire, switch or contact, it can be determined by measuring the resistance with an ohmmeter. Why measure the voltage drop?
To know the difference between resistance detection and voltage drop detection, Electronic weighbridge design Let's take the battery lead as an example to analyze the similarities and differences between the two. There is zero drift, Electronic weighbridge parts Intervene the differential amplifier circuit with symmetrical resistance, and finally say that the resistance of the weighbridge electric valve is difficult to be symmetrical. Learning the circuit connection of the long tail differential amplifier circuit, we encounter a thorny problem: the flicker circuit connection of the bulb. Under the operation of two time relays, the electrical appliance works normally when the delay of each time relay is more than 0.2 seconds, However, if the circuit is short circuited when the delay of one or both is less than 0.2s, the rectifier bridge tripped by the weighbridge electric valve will seal the rectifier tube in a shell.
