概述
柱式傳感器也可稱為柱式測力傳感器，是稱重傳感器的一種，是一種將質量信號轉變為可測量的電信號輸出的裝置，主要有S型、懸臂型、輪輻式、板環式、單點式、橋式、柱筒式等幾種樣式。
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系列傳感器特別為公路地磅而設計，其*的設計理念，并結合裝配模塊，可以有效地平衡機械或者熱膨脹收縮引起的移動。*的幾何設計，精心挑選的材料以及傳感器表面硬度，保證了優異地旋轉特性，高恢復力和*的免維修使用。*的高度和外形設計使得PR6221在不同地受力階段都能保持恒定，其安全過載很高，達到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.
更讓PR6221出眾的是其高精度，高重復性，以及的可靠性和穩定性，使得傳感器年復一年后仍能無障礙操作。擺錘支撐設計，結合自有的測量原件幾何結構，可以使傳感器內部的力傳遞處于*狀態，使測量精度的影響zui小化。同時傳感器可提供超高過載量程范圍。密封外殼和特殊TPE材質電纜線允許傳感器在環境下運作。
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.
結合特殊電阻式應變計技術的PR6221，擁有防雷保護。整個測量鏈不需要砝碼即可進行校準。得益于匹配輸出技術，在很多情況下，傳感器不需要電角校準，在調試期間可以節省大量時間。同時客戶還可以選裝防爆版本。
回復力
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.
傳感器從頂端到垂直軸的每一毫米移動，都會產生0.5%的水平回復力。
傳感器外殼結構
Deep draw pulled housing, membrane and measuring element hermetically sealed, welded, filled with inert gas。
深沖壓牽引外殼，薄膜和測量原件密封和焊接技術，內部充滿惰性氣體。
