詳情介紹
  雙法蘭液位計(jì)是用于防止管道中的介質(zhì)直接進(jìn)入變送器里的壓力傳感器組件,它與變送器之間是靠注滿(mǎn)流體的毛細(xì)管連接起來(lái)的。用于測(cè)量液體、氣體或蒸汽的液位、流量和壓力,然后將其轉(zhuǎn)變成4~20mA DC信號(hào)輸出。
  普通差壓變送器帶上遠(yuǎn)傳密封裝置后,就成為3351DP遠(yuǎn)傳差壓變送器,它仍具有差壓變送器的各種特點(diǎn)。可與HART手操器相互通訊,通過(guò)它進(jìn)行設(shè)定,監(jiān)控。
  一、可避免被測(cè)介質(zhì)直接和變送器的隔離膜片接觸,這種測(cè)量方法適用于下述幾種情況:
  1、被測(cè)介質(zhì)對(duì)變送器敏感元件有腐蝕作用
  2、需要將高溫被測(cè)介質(zhì)與變送器隔離
  3、被測(cè)介質(zhì)中有固體懸浮物或高粘度介質(zhì)
  4、被測(cè)介質(zhì)由引壓管引同時(shí)易固化或結(jié)晶
  5、更換被測(cè)介質(zhì)需嚴(yán)格凈化測(cè)量頭
  6、測(cè)量頭必須保持衛(wèi)生,嚴(yán)禁污染。使用對(duì)象:腐蝕性或粘性的液體
  注意:真空?qǐng)龊喜灰瞬捎眠h(yuǎn)傳變送器。
  二、雙法蘭液位計(jì)遠(yuǎn)傳裝置形式有四種:
  1、1191PFW扁平式遠(yuǎn)傳裝置(標(biāo)準(zhǔn)3″、工作壓力2.5MPa)
  2、1191RTW型螺紋安裝式遠(yuǎn)傳裝置(zui大工作壓力10MPa)
  3、1191RFW型法蘭安裝式遠(yuǎn)傳裝置
  4、1191EFW型插入筒式遠(yuǎn)傳裝置(標(biāo)準(zhǔn)3″或4″,工作壓力2.5MPa)
  三、技術(shù)性能
  1、產(chǎn)品名稱(chēng):法蘭式液位變送器
  2、供 電:24VDC等
  3、量程范圍:0-1.3-31MPa
  4、精度等級(jí):0.2%FS以?xún)?nèi)
  5、輸出信號(hào):4-20MA等信號(hào)/1-5VDC/HART等
  6、適用介質(zhì):氣體、液體等
  7、防護(hù)等級(jí):普通型IP65/潛水型IP68
  8、材質(zhì)類(lèi)型:315L不銹鋼
  9、溫度范圍:-25℃-85℃
  10、環(huán)境條件:溫度-20℃-55℃,相對(duì)濕度5%-9%
  四、安裝使用說(shuō)明
  1、安裝場(chǎng)所沖擊與振動(dòng)
  HD3051LP雙法蘭液位變送器和壓力變送器在出廠(chǎng)設(shè)計(jì)上是可以承受一定的沖擊振動(dòng)的。但也應(yīng)當(dāng)盡量安裝在無(wú)振動(dòng)或振動(dòng)小的場(chǎng)所。
  2、安裝場(chǎng)所環(huán)境溫度條件
  請(qǐng)盡量避免將變送器安裝在環(huán)境溫度變化大的場(chǎng)所,如果安裝位置直接受到熱輻射或暴露在日曬雨淋中,應(yīng)采取防水、隔熱輻射和通風(fēng)措施。
  3、安裝場(chǎng)所環(huán)境空氣條件
  本產(chǎn)品請(qǐng)避免安裝在腐蝕性環(huán)境中,如果使用在腐蝕性環(huán)境中,應(yīng)有良好的通風(fēng)并注意避免腐蝕性氣體或液體浸入電線(xiàn)管內(nèi)。
  4、安裝位置的引用
  HD3051LP雙法蘭液位變送器都對(duì)安裝位置有嚴(yán)格要求,有傾鈄安裝要求時(shí),訂貨時(shí)需附加提出。也可安裝完后重新進(jìn)行零點(diǎn)設(shè)置。
  五、注意事項(xiàng)
  1、緊固測(cè)量容室的四顆螺栓、連接毛細(xì)管和容室部分的固定螺釘絕對(duì)不可松動(dòng),以防止封入液泄漏,造成儀表?yè)p壞。
  2、配線(xiàn)時(shí)應(yīng)避開(kāi)大容量的變壓器、電動(dòng)機(jī)或動(dòng)力用電源等干擾源。配線(xiàn)時(shí)應(yīng)拆開(kāi)電源接口的防塵塞;螺紋部應(yīng)進(jìn)行防水處理。為防止干擾,信號(hào)電纜應(yīng)避免與其他電源電纜穿入同一根電纜保護(hù)管,對(duì)于防爆型儀表,為確保防爆性能,必須按有關(guān)規(guī)定配線(xiàn)。
