橫河儀川壓力變送器特點(diǎn):壓力變送器也稱差變送器,,主要由測壓元件傳感器,、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、液體等壓力信號轉(zhuǎn)變成標(biāo)準(zhǔn)的電流電壓信號,,以供給指示報(bào)警儀,、記錄儀、調(diào)節(jié)器等二次儀表進(jìn)行測量,、指示和過程調(diào)節(jié),。
壓力變送器測量原理是:流程壓力和參考壓力分別作
變送器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),,以使硅片上用半導(dǎo)體技術(shù)制成的全動態(tài)惠斯登電橋在外部電流源驅(qū)動下輸出正比于壓力的mV級電壓信號。由于硅材料的強(qiáng)性,,所以輸出信號的線性度及變差指標(biāo)均很高,。工作時(shí),壓力變送器將被測物理量轉(zhuǎn)換成mV級的電壓信號,,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式放大器,。放大后的信號經(jīng)電壓電流轉(zhuǎn)換變換成相應(yīng)的電流信號,再經(jīng)過非線性校正,zui后產(chǎn)生與輸入壓力成線性對應(yīng)關(guān)系的標(biāo)準(zhǔn)電流電壓信號,。
橫河儀川一體化溫度變送器:一體化溫度變送器一般由測溫探頭(熱電偶或熱電阻傳感器)和兩線制固體電子單元組成,。采用固體模塊形式將測溫探頭直接安裝在接線盒內(nèi),從而形成一體化的變送器,。一體化溫度變送器一般分為熱電阻和熱電偶型兩種類型,。
熱電阻溫度變送器是由基準(zhǔn)單元、R/V轉(zhuǎn)換單元,、線性電路,、
變送器反接保護(hù)、限流保護(hù),、V/I轉(zhuǎn)換單元等組成,。測溫?zé)犭娮栊盘栟D(zhuǎn)換放大后,再由線性電路對溫度與電阻的非線性關(guān)系進(jìn)行補(bǔ)償,,經(jīng)V/I轉(zhuǎn)換電路后輸出一個(gè)與被測溫度成線性關(guān)系的4~20mA的恒流信號,。
熱電偶溫度變送器一般由基準(zhǔn)源、冷端補(bǔ)償,、放大單元,、線性化處理、V/I轉(zhuǎn)換,、斷偶處理,、反接保護(hù)、限流保護(hù)等電路單元組成,。它是將熱電偶產(chǎn)生的熱電勢經(jīng)冷端補(bǔ)償放大后,,再帽由線性電路消除熱電勢與溫度的非線性誤差,zui后放大轉(zhuǎn)換為4~20mA電流輸出信號,。為防止熱電偶測量中由于電偶斷絲而使控溫失效造成事故,,變送器中還設(shè)有斷電保護(hù)電路。當(dāng)熱電偶斷絲或接解不良時(shí),,變送器會輸出zui大值(28mA)以使儀表切斷電源,。
一體化溫度變送器具有結(jié)構(gòu)簡單、節(jié)省引線,、輸出信號大,、抗干擾能力強(qiáng)、線性好,、顯示儀表簡單、固體模塊抗震防潮,、有反接保護(hù)和限流保護(hù),、工作可靠等優(yōu)點(diǎn)。
一體化溫度變送器的輸出為統(tǒng)一的4~20mA信號;可與微機(jī)系統(tǒng)或其它常規(guī)儀表匹配使用,。也可用戶要求做成防爆型或防火型測量儀表,。
