PR6211緊湊型壓式稱重傳感器

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(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 6211 range of load cells is specially designed for weighing silos, tanks and process vessels. The unique design principle facilitates a particularly compact construction and, as a result, the unit can be used even in restricted space conditions. The FlexLock installation kits counterbalance movements arising from mechanical or thermal expansion or contraction of the vessel or its supporting construction.

Sartorius PR6211特別為稱重筒倉，罐秤，料斗秤,過程容器和配料系統(tǒng)等應(yīng)用上。其*的設(shè)計原理使得傳感器結(jié)構(gòu)緊湊，因而其安裝環(huán)境不受限制。其Flexlock裝配套件可以有效平衡由機械或者熱膨脹冷縮引起的移動。

A particular design characteristic of some models is the thin-film or “splutter” technology. This enables an operating temperature of up to 180°C to be reached. In addition, the small construction has integrated overload protection of 500kg. At the same time, this range distinguishes itself above all for its unmatched reliability, robustness and stability, which enable trouble-free operation without adjustment, year after year. The hermetically sealed enclosure and special

TPE cable allows the unit to be used even under extreme operating conditions in harsh production environments.

讓PR6211出眾的不僅是其工作溫度高達180℃，而且在結(jié)構(gòu)緊湊前提下集成500kg的過載保護。不僅如此，其的可靠性和穩(wěn)定性，使得傳感器年復(fù)一年后仍能保持無障礙操作，無需校準(zhǔn)。密封外殼和特殊TPE材質(zhì)電纜線，允許傳感器在環(huán)境下運作

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.

校準(zhǔn)整個測量鏈不需要砝碼，得益于匹配輸出技術(shù)，在不需要再次校準(zhǔn)的情況下，自由替換損壞的傳感器，這樣在調(diào)試期使用用戶可節(jié)省大量時間。同樣PR6221可選配防爆版。
