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)量信號轉(zhuǎn)變?yōu)榭蓽y量的電信號輸出的裝置，主要有S型、懸臂型、輪輻式、波紋管式、單點式、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 6246 range of load cells is specially designed for high-precision weighing of process vessels and for high-precision dosing. Due to the fact that the container is suspended, movements arising from mechanical or thermal expansion or contraction of the vessel or its supporting construction can be counterbalanced. The load cell is manufactured entirely from stainless steel. A particular design characteristic is the compact construction with a high overload range of up to 150% and the highest accuracy class of up to C6.

Sartorius PR6246是一款特別為高精度稱重應(yīng)用，如過程容器和配料應(yīng)用，而設(shè)計的稱重傳感器。傳感器能平衡機械或者熱膨脹冷縮造成的移動。整個傳感器為不銹鋼材質(zhì)，其特別的設(shè)計使得傳感器維持緊湊的外形的同時，仍能保持高達150%的過載能力和C6級別的精度。

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. 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.

更讓PR6246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。

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.

整個測量鏈不需要砝碼即可進行校準，得益于自有的匹配輸出技術(shù)，無需再次校準即可對損壞的傳感器進行更換，節(jié)省大量時間。作為選配，可選裝防爆版本。
