The course of work of the present utility model is: instrument powers on, instrument runs to original state automatically, promptly face toward upper limit facing to positioning of rotating point and limiting plate near switch, instrument this moment pilot lamp in place is bright, 20 Fume collectors are placed on the setting-out dish successively, press START button, the instrument run indicator is bright, instrument pilot lamp in place goes out, instrument is according to decline, the stable time-delay of balance (computing machine timing acquiring balance data), rise, the order of rotation 18 degree repeats 20 cycles, can be placed into weighing on the balance to 20 Fume collectors successively, after weighing finished, the instrument run indicator was gone out.Above operating process only need carry out twice, can obtain the tare weight and the gross weight of 20 Fume collectors respectively, subtracts each other to obtain net weight.

The utility model has following advantage:

1, robotization, sequencing.The CPU224CN Controlled by Programmable Controller that adopts company limited of Siemens (China) to produce realizes control setting-out automatically, sampling, full name amount process automation, intellectuality in Fume collector weighing process.

2, efficient.The utility model energy one-time continuous is finished the automatic weighing to 20 Fume collectors, and 20 Fume collectors weighing are placed on the setting-out dish, presses START button, and the weighing process is finished automatically, need not manual control, has improved work efficiency.

3, reliable.Whole weighing process is finished automatically, need not manually-operated, has avoided manually-operated error, effectively guarantees the reliability of weighing data.
