溫度變送器在鍋爐環(huán)境中使用時(shí)，需要注意以下幾點(diǎn)：1、溫度變送器在使用時(shí)，標(biāo)注的接地點(diǎn)必須全部有效接地。2、溫度變送器的外殼默認(rèn)為地，所以要求現(xiàn)場(chǎng)設(shè)備有效接地。3、現(xiàn)場(chǎng)使用者必須確保所用線纜的外徑在卡套允許的范圍之內(nèi)。另外還要確保線纜穩(wěn)固無間隙的安裝在卡套中。壓線帽鎖緊直徑5～9mm。4、要確保溫度變送器旋緊壓線鎖，以確保溫度變送器的防護(hù)等級(jí)。 </p> <p> 溫度變送器的檢測(cè)內(nèi)容包括以下幾個(gè)方面： </p> <p> 一：外觀檢測(cè)；需要對(duì)溫度變送器的外殼進(jìn)行有無脫漆、破損、裂痕以及被撞擊痕跡和緊固件缺損等情況的檢測(cè)。 </p> <p> 第二：內(nèi)部檢測(cè)；溫度變送器的元器件、零配件、連接件等有無缺損、斷裂、變形、腐蝕、密封不良等情況。 </p> <p> 第三：感溫元件檢測(cè)；溫度變送器的感溫元件和引線應(yīng)保持清潔、干燥、完整、無銹。保護(hù)套管完整無損、無凹痕、劃痕和明顯銹蝕等現(xiàn)象。 </p> <p> 第四：溫度變送器的計(jì)量性檢測(cè)（可以采用兩種方式）：帶傳感器檢測(cè)：就是將溫度變送器傳感部分插入到標(biāo)準(zhǔn)溫度源，通過改變標(biāo)準(zhǔn)溫度輸入，校準(zhǔn)溫度變送器的輸出電流。不帶傳感器檢測(cè)：斷開溫度變送器的傳感元件（熱電阻、熱電偶）使用標(biāo)準(zhǔn)電阻源及過程檢測(cè)設(shè)備，校準(zhǔn)溫度變送器的信號(hào)轉(zhuǎn)換部分。 </p> <p> <br /> </p><p> 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明書接線，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。一體化溫度變送器一般分為熱電阻和熱電偶型兩種類型。</p><div

<p> 溫度變送器在正常使用的過程中，因?yàn)楝F(xiàn)場(chǎng)、環(huán)境以及配套的儀表的千差萬別，會(huì)對(duì)其產(chǎn)生不同的影響。浪涌就是對(duì)溫度變送器zui 常見、zui 嚴(yán)重的損壞者。浪涌的物理術(shù)語解釋是瞬間出現(xiàn)超出穩(wěn)定值的峰值。也就是超出正常工作電壓的瞬間過電壓。溫度變送器在現(xiàn)場(chǎng)的使用過程中，如果受到幾百萬分之一秒時(shí)間內(nèi)的一種劇烈脈沖，幾乎很難幸免。重型設(shè)備、短路、電源切換或大型發(fā)動(dòng)機(jī)，都可能造成浪涌。影響溫度變送器安全功用的主要因家有失效形式和自確診。陜西供水管網(wǎng)溫度變送器價(jià)格</p><p
