概述

The PR 6211 range of load cells is specially designed for weighing silos, tanks and process vessels. The unique design principle facilitates a particularly compact construction and, as a result, the unit can be used even in restricted space conditions. The FlexLock installation kits counterbalance movements arising from mechanical or thermal expansion or contraction of the vessel or its supporting construction.

光栅式传感器利用光栅形成的莫尔条纹把角位移转换成光电信号（图2）。光栅有两块，一为固定光栅，另一为装在表盘轴上的移动光栅。加在承重台上的被测物通过传力杠杆系统使表盘轴旋转，带动移动光栅转动，使莫尔条纹也随之移动。利用光电管、转换电路和显示仪表，即可计算出移过的莫尔条纹数量，测出光栅转动角的大小，从而确定和读出被测物质量。

码盘式传感器 的码盘（符号板）是一块装在表盘轴上的透明玻璃，上面带有按一定编码方法编定的黑白相间的代码。加在承重台上的被测物通过传力杠杆使表盘轴旋转时，码盘也随之转过一定角度。光电池将透过码盘接受光信号并转换成电信号，然后由电路进行数字处理，最后在显示器上显示出代表被测质量的数字。光电式传感器曾主要用在机电结合秤上。

它利用电容器振荡电路的振荡频率f与极板间距d 的正比例关系工作 。极板有两块，一块固定不动，另一块可移动。在承重台加载被测物时，板簧挠曲，两极板之间的距离发生变化，电路的振荡频率也随之变化。测出频率的变化即可求出承重台上被测物的质量。电容式传感器耗电量少，造价低，准确度为1/200～1/500。

1、敏感元件

直接感受被测量(质量)并输出与被测量有确定关系的其他量的元件。如电阻应变式称重传感器的弹性体，是将被测物体的质量转变为形变;电容式称重传感器的弹性体将被测的质量转变为位移。

2、变换元件

又称传感元件，是将敏感元件的输出转变为便于测量的信号。如电阻应变式称重传感器的电阻应变计(或称电阻应变片)，将弹性体的形变转换为电阻量的变化;电容式称重传感器的电容器，将弹性体的位移转变为电容量的变化。有时某些元件兼有敏感元件和变换元件两者的职能。如电压式称重传感器的压电材料，在外载荷的作用下，在发生变形的同时输出电量。

3、测量元件

将变换元件的输出变换为电信号，为进一步传输、处理、显示、记录或控制提供方便。如电阻应变式称重传感器中的电桥电路，压电式称重传感器的电荷前置放大器。

4、辅助电源

为传感器的电信号输出提供能量。一般称重传感器均需外链电源才能工作。因此，作为一个产品必须标明供电的要求，但不作为称重传感器的组成部分。有些传感器，如磁电式速度传感器，由于他输出的能量较大，故不需要辅助电源也能正常工作。所以并非所有传感器都要有辅助电源。
