一體化溫度變送器接線的主要注意事項(xiàng)。1、布線：一體化溫度變送器的安全火花回路的接線（輸入信號(hào)線），必須是帶有絕緣套或屏蔽的導(dǎo)線，并且和非安全火花回路的接線彼此隔離，以免互相混觸。2、不同型號(hào)的一體化溫度變送器按說(shuō)明書(shū)接線，對(duì)于具有安全火花回路的防爆儀表接線時(shí)一定不能接錯(cuò)，并要仔細(xì)檢查是否有短接或接錯(cuò)。3、使用一體化溫度變送器時(shí)，要特別注意普通型與本安型之分，普通型不能安裝在危險(xiǎn)區(qū)，本安型可以安裝在危險(xiǎn)區(qū)。4、熱電阻一體化溫度變送器輸入為三線制各連接導(dǎo)線的線路電阻應(yīng)相等并處于同一環(huán)境溫度內(nèi)。5、對(duì)于防爆儀表原則上不允許拆卸安全火花回路的元件和調(diào)換一體化溫度變送器接線，如需要更換，則應(yīng)按防爆要求進(jìn)行。6、定期檢查一體化溫度變送器時(shí)，為了精確地讀出數(shù)據(jù)，要在輸出端子之間，連接數(shù)字電壓表進(jìn)行測(cè)量，而不要拿掉安全火花回路線。7、一體化溫度變送器出現(xiàn)故障后，應(yīng)停電進(jìn)行檢查，未查出故障不得送電。8、溫度變送器在運(yùn)行中應(yīng)保持清潔。工業(yè)生產(chǎn)中等重要的數(shù)據(jù)測(cè)量，需要用帶金屬外殼的溫度變送器，這類溫度變送器作業(yè)時(shí)間較長(zhǎng)，也很耐高溫。河北卡箍式溫度變送器怎么樣</p><p
