PR6251圓餅式稱重傳感器

概述

稱重傳感器，又稱為測力傳感器和壓力傳感器，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、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 6251 range of load cells is specially designed for easy weighing of silos and horizontal tanks. The unique design principle ensures a very compact construction. As a result, existing applications can also be upgraded very easily. The range distinguishes itself above all for its unmatched reliability, robustness and stability, which enable trouble-free operation without adjustment, year after year.

Sartorius PR6251的所有量程都為筒倉和臥式油槽稱重測量應用而設計，氣*的設計理念使得PR6251結構緊湊，現有應用更新操作簡單。的可靠性、穩健性和穩定性使得傳感器年復一年后仍能無障礙操作，無須校準。

Special measuring element geometry ensures that the transmission of force into the sensor is always at the optimum level. This minimizes the effect on measurement accuracy whilst a high overload range, high repeatability and good 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 allow the unit to be used even under extreme operating conditions in harsh production environments.

PR6251測量元件的特殊幾何結構總能確保傳感器機身內部力傳遞處于*水準，實現高量程超載對精度影響的zui小化，保持良好的重復性與線性。得益于*地電阻應變計技術，PR6251的工作溫度范圍非常廣。其全密封外殼和特殊TPE材質電纜線使得傳感器能在惡劣操作環境無障礙應用。

The entire measurement chain can be calibrated without the use of a reference weight.

A version is also available with a direct output of 4…20 mA. This facilitates easy and cost-effective integration into an existing application. An explosion-proof (Ex) version of this range of load cells is also available, as an option, for use in intrinsically safe environments.

整個量測鏈無須砝碼即可校準，用戶可單獨4-20mA輸出模塊，并整合到目前即有應用上，簡單劃算。所有量程都有防爆版本可選。
