概述
The PR 6201 range of load cells is specially designed for weighing silos, tanks and process vessels. The unique design principle, in combination with the FlexLock installation kits, makes it possible to counterbalance movements arising from mechanical or thermal expansion or contraction of the vessel or its supporting construction. A particular design characteristic is that the overall height and shape of the load cell remain unchanged, even after two decades of use. Alongside this, the unit has an especially high overload capacity of up to 200%.
称重传感器实际上是一种将质量信号转变为可测量的电信号输出的装置。用传感器应先要考虑传感器所处的实际工作环境，这点对正确选用称重传感器至关重要，它关系到传感器能否正常工作以及它的安全和使用寿命，乃至整个衡器的可靠性和安全性。在称重传感器主要技术指标的基本概念和评价方法上，新旧国标有质的差异。主要有S型、悬臂型、轮辐式、板环式、膜盒式、桥式、柱筒式等几种样式。
