Minebea Intec稱重傳感器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(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、板環(huán)式、膜盒式、橋式、柱筒式等幾種樣式。

The Sartorius PR 6201 range of load cells is specially designed for weighing silos, tanks and process vessels. 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. A particular design characteristic is that the overall height and shape of the load cell remain unchanged, even after two decades of use. Alongside this, the unit has an especially high overload capacity of up to 200%。

德國Sartorius PR6201的量程是專為稱重筒倉，槽罐配料和過程容器應(yīng)用而設(shè)計。其無二的設(shè)計原理，結(jié)合FlexLock的裝配套件，使得平衡容器或者其支撐結(jié)構(gòu)上機械或熱的膨脹收縮而引起的移動成為可能。PR6201的特點是即使使用幾十年，仍能保證傳感器的高度和形狀不會發(fā)生變化。此外，過載能力可達到傳感器總量程的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, high repeatability and perfect linearity。

PR6201不僅量程突出，而且精度和重復(fù)性高，其可靠性、穩(wěn)健性和穩(wěn)定性更是，使得傳感器能年復(fù)一年地?zé)o障礙運作，無需校準(zhǔn)。鐘擺支撐的原理，結(jié)合申請的測量元件幾何設(shè)計，使得傳遞到傳感器內(nèi)部的力傳遞一直處在宜水準(zhǔn)，盡量減小影響精度的要素。與此同時，傳感器提供超高的量程過載范圍，良好的重復(fù)性以及優(yōu)異的線性度。

There is an especially 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. 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

PR6201特別廣的工作溫度范圍要歸功于特殊的電阻應(yīng)變技術(shù)。高密封的外殼與特殊TPE材質(zhì)的電纜線使得PR6201輕松應(yīng)對苛刻的操作和生產(chǎn)環(huán)境。整個測量鏈不需要砝碼即可進行校準(zhǔn)，得益于自有的配對輸出技術(shù)，無需再次校準(zhǔn)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。

回復(fù)力

For each mm of displacement, that the top of the load cell is shifted from the vertical axis, a horizontal restoring force of 0.5% of the applied load is generated。

傳感器頂部離縱軸每偏移1mm，傳感器會產(chǎn)生一個水平方向的回復(fù)力，大小為外施載荷的0.5%。

傳感器外殼

Full stainless steel housing, membrane and measuring element hermetically sealed, welded, filled with inert gas。

不銹鋼外殼，薄膜和感應(yīng)元件都密封與焊接，并且內(nèi)部充滿了惰性氣體。

防護等級

IP 68, IEC529 (equivalent to NEMA 6). The load cell can be submerged in water to a depth of 1.5m for 10,000 hours。

防護等級，IP68，IEC529的防護標(biāo)準(zhǔn)，相當(dāng)于NEMA6標(biāo)準(zhǔn)（水下、防塵、防水）。傳感器可下潛至水下1.5m，并正常工作10000個小時。
