一、產品概述product introduction
失重秤采用靜態(tài)計量結構、周期循環(huán)控制方式，具有極高的計量精度，廣泛應用于玻璃、建材、水泥、塑料、冶煉、礦山、化工等行業(yè)。
Weightlessness scale using the static measurement structure, cycle control mode, the measurement accuracy is high, widely used in building material, glass, cement, plastic, bllurgy, mine, chemical industry etc..
二、工作原理Work principle
失重秤采用周期計量控制方式，設置好周期時間和周期重量，在周期內，首先通過上給料機向計量料斗進料，當進料大于設定重量時，停止進料，微機記錄下現在的重量值，然后控制下給料機開始排料，當排料量接近設定重量時，改為慢速排料方式，直到等于設定重量，停止下給料機排料，等待周期結束后，進入下一個周期循環(huán)運行，因為計量時處于靜態(tài)計量方式，所以有極高的計量精度。
Weightlessness scale using periodic measurement control mode, set up the cycle time and cycle of weight in the period, first through the feeder to the metering hopper feed, when the material is greater than the set weight, stop feeding, microcomputer recording now under the weight value, and then under the control of feeder began to discharge, when discharging quantity of close set the weight, to slow the discharging b, until it is equal to the set weight, stop feeder discharge, waiting for the end of cycle, into the next cycle of operation, as measured in static measurement mode, so the measurement precision.
