柱式传感器也可称为柱式测力传感器,是称重传感器的一种,是一种将质量信号转变为可测量的电信号输出的装置,主要有S型、悬臂型、轮辐式、板环式、单点式、桥式、柱筒式等几种样式。

The PR 6221 range of load cells is designed exclusively for use on road weighbridges. The unique design principle, combined with the installation kits, counterbalances movements caused by mechanical or thermal expansion or contraction of the weighbridge construction. The unique combination of the selected geometry and material/surface hardness parameters guarantees perfect rolling characteristics, high restoring forces and long-term maintenance-free operation.

A particular design characteristic is that the height and shape of the load cell remain constant over various load stages, whilst there is a particularly high overload range of, in part, up to 200%.

Sartorius PR6221系列传感器特别为公路地磅而设计,其无二的设计理念,并结合装配模块,可以有效地平衡机械或者热膨胀收缩引起的移动。的几何设计,精心挑选的材料以及传感器表面硬度,保证了优异地旋转特性,高恢复力和长期的免维修使用。的高度和外形设计使得PR6221在不同地受力阶段都能保持恒定,其安全过载很高,达到200%。

 

At the same time, this range distinguishes itself – in addition to its high measurement accuracy and repeatability – above all for its unmatched reliability, robustness and stability, which enable trouble-free operation without adjustment, year after year. The pendulum support principle, combined with patented measuring element geometry, ensures that force transmission into the sensor is always at the optimum level and, in this way, the effect on measurement accuracy is minimized. At the same time, the load cell offers a particularly high overload range. The hermetically sealed enclosure and special TPE cable allow the unit to be used even under extreme operating conditions.

更让PR6221出众的是其高精度,高重复性,以及的可靠性和稳定性,使得传感器年复一年后仍能无障碍操作。摆锤支撑设计,结合自有的测量原件几何结构,可以使传感器内部的力传递处于状态,使测量精度的影响最小化。同时传感器可提供超高过载量程范围。密封外壳和特殊TPE材质电缆线允许传感器在环境下运作。

 

Special resistance strain gauge technology, in combination with the PR6021/.. cable junction boxes, provides for demonstrably improved lightning protection. The entire measurement chain can be calibrated without the use of a reference weight. Due to “matched output" technology, in many cases electrical corner adjustment is not required. This saves a tremendous amount of time during commissioning. An explosion-proof (Ex) version of this range of load cells is also available, as an option, for use in intrinsically safe environments.

结合特殊电阻式应变计技术的PR6221,拥有防雷保护。整个测量链不需要砝码即可进行校准。得益于匹配输出技术,在很多情况下,传感器不需要电角校准,在调试期间可以节省大量时间。同时客户还可以选装防爆版本。

 

回复力

For each mm of movement that the top of the load cell shifts from the vertical axis, a horizontal restoring force of 0.5 % of the applied vertical load is generated.

传感器从顶端到垂直轴的每一毫米移动,都会产生0.5%的水平回复力。

 

传感器外壳结构

Deep draw pulled housing, membrane and measuring element hermetically sealed, welded, filled with inert gas

深冲压牵引外壳,薄膜和测量原件密封和焊接技术,内部充满惰性气体。
