稱重傳感器，又稱為測力傳感器和壓力傳感器，是一種將質(zhì)量信號(hào)轉(zhuǎn)變?yōu)榭蓽y量的電信號(hào)輸出的裝置，主要有S型、懸臂型、輪輻式、波紋管式、單點(diǎn)式、橋式、柱式等幾種樣式。稱重傳感器的工作原理原理上稱重傳感器就是壓力傳感器, 只是形狀不一樣而已。

The PR 6241 range of load cells is specially designed for weighing small and mediumsized process vessels and for high-precision dosing. 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. The load cell is manufactured entirely from stainless steel. A particular design characteristic

is the combination of “genuine" shear force and pendulum support principles, which make for unrivalled accuracy.

Sartorius PR6241是一款特別為中小型稱重和過程容器以及高精度配料應(yīng)用而設(shè)計(jì)的稱重傳感器，其無二的設(shè)計(jì)理念，結(jié)合Flexlock裝配模塊，使得傳感器能平衡機(jī)械或者熱膨脹冷縮造成的移動(dòng)。整個(gè)傳感器為不銹鋼材質(zhì)，整合剪切力與鐘擺支撐，使得PR6241的精度非常高。

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. With the associated installation kit, the pendulum support principle ensures that force transmission into the sensor is always at the optimum level and, in this way, the effect on measurement accuracy is minimized, whilst high repeatability and perfect linearity are maintained.

更讓德國Sartorius PR6241出眾的是其高精度，高重復(fù)性，以及的可靠性和穩(wěn)定性，使得傳感器年復(fù)一年后仍能無障礙操作。結(jié)合裝配套件和擺錘支撐，使得傳感器內(nèi)部的力傳遞處于狀態(tài)，使測量精度的影響最小化，保持高重復(fù)性和線性。

There is a particularly wide working temperature range attributable to special resistance strain gauge technology. The hermetically sealed enclosure and special

TPE cable allows the unit to be used even under extreme operating conditions in harsh production environments. The entire measurement chain can be calibrated without the use of a reference weight. Due to “matched output" technology, a damaged load cell can be exchanged without the need for re-calibration. 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.

PR6241特別廣的工作溫度范圍要?dú)w功于特殊的電阻應(yīng)變技術(shù)。高密封的外殼與特殊TPE材質(zhì)的電纜線使得傳感器可在苛刻的操作和生產(chǎn)環(huán)境正常工作。整個(gè)測量鏈不需要砝碼即可進(jìn)行校準(zhǔn)，得益于自有的匹配輸出技術(shù)，無需再次校準(zhǔn)即可對(duì)損壞的傳感器進(jìn)行更換，節(jié)省大量時(shí)間。作為選配，可選裝防爆版本。
