隔爆型,本安型帶熱電阻溫度變速器,SBWZ-4480/44SI,主要特點: ● 采用硅橡膠或環(huán)氧樹脂密封結(jié)構(gòu),因此耐震、耐濕,適合在現(xiàn)場環(huán)境中安裝使用; ● 現(xiàn)場安裝在熱電偶,熱電阻的接線盒內(nèi)使用,直接輸出4-20mA、0-10mA的輸出信號。這樣既節(jié)約了昂貴的補償導(dǎo)線費用,又提高了信號遠(yuǎn)距離傳輸過程中的抗干擾能力; ● 熱電偶變送器具有冷端自動補償功能;精度高、功耗低,使用環(huán)境溫度范圍寬,工作穩(wěn)定可靠; ● 適用范圍廣,即可以與熱電偶,熱電阻形成一體化現(xiàn)場安裝結(jié)構(gòu),也可以作為功能模塊安裝在檢測設(shè)備中和儀表盤上使用: 工作原理: 熱電偶或熱電阻傳感器被溫度轉(zhuǎn)換成電信號,再將信號送入變送器的輸入網(wǎng)絡(luò),該網(wǎng)絡(luò)包含調(diào)零和熱電偶補償?shù)认嚓P(guān)電路。經(jīng)調(diào)零后的信號輸入到運算放大器進(jìn)行信號放大,放大的信號一經(jīng)V/I轉(zhuǎn)換器運算處理后以DC4-20mA電流輸出;另一路經(jīng)A/D轉(zhuǎn)換器處理后到表頭顯示。變送器的線性化電路有兩種,均采用反饋方式。對熱電阻傳感器,用正反方式校正,對熱電偶傳感器,用多段折線逼近法進(jìn)行校正。一體化數(shù)字顯示溫度變送器LCD顯示的采用兩線制方式輸出。
