称重传感器，又称为测力传感器和压力传感器，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、波纹管式、单点式、桥式、柱式等几种样式。称重传感器的工作原理原理上称重传感器就是压力传感器, 只是形状不一样而已。

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是一款特别为高精度称重应用，如过程容器和配料应用，而设计的称重传感器。传感器能平衡机械或者热膨胀冷缩造成的移动。整个传感器为不锈钢材质，其特别的设计使得传感器维持紧凑的外形的同时，仍能保持高达150%的过载能力和C6级别的精度。

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.

更让PR6246出众的是其高精度，高重复性，以及无与伦比的可靠性和稳定性，使得传感器年复一年后仍能无障碍操作。结合装配套件和摆锤支撑，使得传感器内部的力传递处于最佳状态，使测量精度的影响最小化，保持高重复性和完美线性。

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.

整个测量链不需要砝码即可进行校准，得益于自有的匹配输出技术，无需再次校准即可对损坏的传感器进行更换，节省大量时间。作为选配，可选装防爆版本。
