秤体轴圆盘、转子、传动机构、支点、称重传感器、测速传感器、秤架、进出料口等组成。
一对支点设置在圆盘的中心线上,称重传感器设置在两支点联线的垂直平直分线上,测速传感器安装在托动电机轴的尾端,支点如同天平刀口,未下料时,调节平衡装置,使圆盘相对于支点处于平衡状态,转子由一系列叶片组成,叶片与圆盘壁围成一格一格的旋转空间,当下料时,物料从进料口进入这些空间,并随着转子的转动到达出料口排出。
此时,相对与支点,圆盘里一半有物料,一半没有物料,使圆盘的两个半圆相对于支点失去平衡,称重传感器受力,这个力与圆盘内物料的重量成正比。
设物料均匀分布,圆盘内的料重为P(㎏),称重传感器受力为F(㎏),则F=C1P (1)(式中C1P为比例常数,它的大小只与P和F关于支点的力臂有关)很明显,当转子均匀送料时,转子每旋转一周所输送的物料正为2P,又设此时测速传感器所检测到的转子的转速信号为n(周/分),则物料的流量Q(t/h)为:Q=2P/100(nx60)=0.12/C1Fn=K1Fn (2)由(2)式得知,通过转子秤物料的流量,取决于称重传感器受力F和测速传感器转速n 的乘积,由此,可求得T(小时)通过转子秤的物料累计量W(吨)。

Small -scale load cell structure , type and more categories . In order to make the load cell has good linearity , strong input sensitivity and strong resistance to lateral load force , we have adopted a two-hole parallel beam load cell [1] ( Figure 2 ),as the use of domestic hard aluminum alloy LY12 elastomer material, the elastic hysteresis and creep is small, the small -scale load cell, the storage of this material is larger than W, elastic modulus is small (about 1 / 3 of steel), the manufacture of small the load cell weighing scale , and the ideal material.Working principle of the sensor is : When the sensor is subjected to external loads prole of the upper and lower beams parallel elastomer elastic deformation / paste in a parallel beam of four strain gauges R1~ R4 consists of bridge output voltage is generated with linearized external load increment p , p can know the size of the external load.Size of the sensor according to the maximum range of the elastic element may be primarily determined detection point ( peak stress ) section thickness h1,, to determine the form and size of the opening , the sensor sensitivity is generally require (1.5 ~ 2) mV / V range, the full-bridge The output voltage U 0.As 0CC U S U ε=,Where: S-strain gauge sensitivity factor;U C C - -for the bridge voltageε-Detection Point (strain gauge affixed at) strain,S U U CC /)/(0=εAlso 1/P M E W ε= ,Where: Mp-detection point bending moment;E -modulus of elasticity of the material;W1-detection point flexural modulus; .)6/(211bh l W =Beacuse ),2/(:)2/(:max L l M M P = (Similar triangles);So ,4/)4/)(/(pl pL L l M P -=Where: b -elastic element width;h1-sectional thickness detection point ;Mmax = pL/4- maximum bending moments at both ends of the elastic element ; p-Maximum weight;l-double hole center distance;L-length of elastomersCan push 164pl h Ebε= Open hole diameter 12h φα=-,2()/2h L l φ=--The stiffness ratio αL h h K 312)(= . This value can be used as calibration values estimated elastic stiffness is adequate.

For each level of the supply voltage circuit for this is not enough , so the choice of switching to Boost Regulator Manifold TL499A for power conversion ( Figure 3 ).The output voltage of the regulator TL499A range of up to 2.9 ~ 30V, output current of 100mA, the required input voltage range of 1.1 ~ 10V. TL499A the battery voltage up to 15V, 7.5V and then get a symmetrical voltage output through the op amp. (2) Reduce the influence of the equivalent offset voltage measurement accuracy ; bridge output signal is superimposed on a high voltage DC supply mold weak signal , you should first ensure that the power bridge to get a high degree of stability , constant current bridge uses circuitry as shown in ( 4 ) below.By the A1, R5, R6, R1 constitute a constant current source circuit for providing a high degree of stability bridge power circuit . R1-R4 constituting the detection resistance strain gauge bridge force due to the action of the force to deform the elastic body , leaving a corresponding change in strain gauge resistance , thereby weak bridge output voltage signal proportional to the force by the elastic body , Rp is zero potentiometer to adjust the bridge output to zero. A2-A5 and peripheral components of the differential amplifier . The circuit has an input impedance (300-500mΏ) high , high common mode rejection ratio (110DB). Input offset voltage (20uv) and offset voltage drift (0.25-10uv / ℃) small features, ideal for the bridge amplifier circuit form .

These need to be addressed in a future circuit improvements . As electronic scales small, easy to carry , such as to further reduce costs in the civilian market will have good prospects for use A/D conversion and the reality circuit ICL7106 completed by the manifold , range conversion by changing the reference voltage VREF 7106 implementation.

中英文对照翻译(文档含英文原文和中文翻译)温度控制简介和PID控制器过程控制系统自动过程控制系统是指将被控量为温度、压.力、流量、成份等类型的过程变量保持在理想的运行值的系统。
实际上过程是动态的。
变化总是会出现,此时如果不采取相应的措施,那些与安全、产品质量和生产率有关的重要变量就不能满足设计要求。
为了说明问题,计我们来看一下热交换器。
流体在这个过程中被压缩的过热蒸汽加热,如图1所示。
图1热交换器这一装置的主要目的是将流体由入口温度Ti(t).加热到某一期望的出口温度T (t)。
如前所述,加热介质是压缩的过热蒸汽。
只要周围没有热损耗,过程流体获得的热量就等于蒸汽释放的热量,即热交换器和管道问的隔热性很好。
很多变量在这个过程中会发生变化,继而导致出日温度偏离期望值。
如果出现这种情况,就该采取一些措施来校正偏差,其目的是保持出日温度为期望值。
实现该目的的一种方法是首先测量r(0),然后与期望值相比较,由比较结果决定如何校正偏差。
蒸汽的流量可用于偏差的校.正。
就是说,如果温度高于期望值,就关小蒸汽阀来减小进入换热器的蒸汽流量;:若温度低于期望值,就开大蒸汽阀,以增加进入换热器的蒸汽流量。
所有这些操作都可由操作员手工实现,操作很简单,不会出现什么问题。
但是,由于多数过程对象都有很多变量需要保持为某一期望值,就需要许多的操作员来进行校正。
因此,我们想自动完成这种控制。
就是说,我们想利用无需操作人员介入就可以控制变量的设备。
这就是所谓自动化的过程控制。
为达到上述日标,就需要设计并实现一个系统。
图2所示为一个可行的控制系统及其基本构件。
图2热交换器控制循环首先要做的是测量过程流体的出口温度,这一任务由传感器(热电偶、热电阻等)完成。
将传感器连接到变送器上,由变送器将传感器的输出信号转换为足够大的信号传送给控制器。
控制器接收与温度相关的信号并与期望值比较。
根据比较的结果,控制器确定保持温度为期望值的控制作用。
基于这一结果,控制器再发一信号给执行机构来控制蒸汽流量。
