德國(guó)E+H固體雷達(dá)物位計(jì)FMR250-AEE1XCJAA2K適合測(cè)量高位貯倉(cāng)中粉塵嚴(yán)重的固體散料，也適合高研磨作用的固體散料
應(yīng)用領(lǐng)域
FMR250用于測(cè)量高位貯倉(cāng)中粉塵嚴(yán)重的固體散料，例如水泥、生料或動(dòng)物飼料等；可應(yīng)用于溫度達(dá)200 °C (392 °F)的場(chǎng)合如水泥孰料或飛灰；可應(yīng)用于具強(qiáng)研磨作用的固料如鐵素體。配備DN80或DN100喇叭型天線的FMR250用于標(biāo)準(zhǔn)型應(yīng)用和小型尺寸的安裝短管。FMR250因配備的DN200或DN250拋物形天線的波束角只有4°或3.5°，成為適用許多安裝場(chǎng)合的理想儀表

FMR250-AEE1XCJAA2KMicropilot FMR250特別適合測(cè)量高位貯倉(cāng)中的固體散料、也適合高溫場(chǎng)合和高研磨作用的固體散料。FMR250內(nèi)置空氣清潔器，適用粉塵嚴(yán)重或介質(zhì)黏附的工況條件。Micropilot FMR250適合粉狀、粒狀等固體散料的連續(xù)性、非接觸式物位測(cè)量。測(cè)量值不受粉塵、進(jìn)料噪音、溫度層、氣體層的影響。
優(yōu)勢(shì)
非接觸式測(cè)量：測(cè)量幾乎不受介質(zhì)特性影響
兩線制技術(shù)，價(jià)格低廉：真正代替了壓差、浮子或浮筒式物位測(cè)量方法
兩線制技術(shù)節(jié)約布線成本，方便接入現(xiàn)有系統(tǒng)
利用Endress+Hauser操作軟件，方便儀表調(diào)試、文件建檔和故障診斷
通過(guò)菜單式的字母數(shù)字顯示模塊，現(xiàn)場(chǎng)操作簡(jiǎn)便
可進(jìn)行限位監(jiān)控（高限，底限），通過(guò) IEC 61508 和 IEC 61511認(rèn)證，達(dá)到SIL2功能安全等級(jí)
支持HART或PROFIBUS PA等FOUNDATION基礎(chǔ)現(xiàn)場(chǎng)總線協(xié)議
