3U-SZC系列失重秤

3U-SZC series of weightlessness scale

一、产品概述product introduction

失重秤采用静态计量结构、周期循环控制方式，具有极高的计量精度，广泛应用于玻璃、建材、水泥、塑料、冶炼、矿山、化工等行业。

Weightlessness scale using the static measurement structure, cycle control mode, the measurement accuracy is high, widely used in building material, glass, cement, plastic, metallurgy, mine, chemical industry etc..

二、工作原理Work principle

失重秤采用周期计量控制方式，设置好周期时间和周期重量，在周期内，首先通过上给料机向计量料斗进料，当进料大于设定重量时，停止进料，微机记录下现在的重量值，然后控制下给料机开始排料，当排料量接近设定重量时，改为慢速排料方式，直到等于设定重量，停止下给料机排料，等待周期结束后，进入下一个周期循环运行，因为计量时处于静态计量方式，所以有极高的计量精度。

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 method, 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.
