全新進(jìn)口BURKERT壓力變聲器原理
BURKERT壓力變送器也稱差變送器,主要由測(cè)壓元件傳感器、模塊電路、顯示表頭、表殼和過程連接件等組成。它能將接收的氣體、液體等壓力信號(hào)轉(zhuǎn)變成標(biāo)準(zhǔn)的電流電壓信號(hào),以供給指示報(bào)警儀、記錄儀、調(diào)節(jié)器等二次儀表進(jìn)行測(cè)量、指示和過程調(diào)節(jié)。
BURKERT壓力變送器測(cè)量原理是:流程壓力和參考?jí)毫Ψ謩e作用于集成硅壓力敏感元件的兩端,其差壓使硅片變形(位移很小,僅μm級(jí)),以使硅片上用半導(dǎo)體技術(shù)制成的全動(dòng)態(tài)惠斯登電橋在外部電流源驅(qū)動(dòng)下輸出正比于壓力的mV級(jí)電壓信號(hào)。由于硅材料的強(qiáng)性,所以輸出信號(hào)的線性度及變差指標(biāo)均很高。工作時(shí),壓力變送器將被測(cè)物理量轉(zhuǎn)換成mV級(jí)的電壓信號(hào),并送往放大倍數(shù)很高而又可以互相抵消溫度漂移的差動(dòng)式放大器。放大后的信號(hào)經(jīng)電壓電流轉(zhuǎn)換變換成相應(yīng)的電流信號(hào),再經(jīng)過非線性校正,zui后產(chǎn)生與輸入壓力成線性對(duì)應(yīng)關(guān)系的標(biāo)準(zhǔn)電流電壓信號(hào)。
BURKERT壓力變送器根據(jù)測(cè)壓范圍可分成一般壓力變送器(0.001MPa~20MP3)和微差壓變送器(0~30kPa)兩種。
