零位補償區(qū)域Zero?compensation?areaSF6-氣體密度繼電器/遠傳密度繼電器帶有零位補償區(qū)域。儀表指針在無壓力狀態(tài)下，因為溫度的升高或降低，會在零位補償區(qū)域擺動，例如：60℃指針指示在低于零位的零位補償區(qū)域下邊緣，從而簡單的測量出溫度補償值，當(dāng)儀表溫度降低,指針將移向零位補償區(qū)域的正值區(qū)域。SF6-?gas?density?monitor?/remote?gas?density?monitor?of?this?model?has?a?zero?compensation?area.?In?the?pressure-free?state,?the?pointer?swings?within?the?zero?compensation?area?due?to?temperature?rise?or?fall.?For?instance,?60℃?pointer?stays?at?the?lower?edge?of?zero?compensation?area?below?zero?position?and?the?temperature?compensation?value?can?be?calculated?in?a?simple?way.?When?the?instrument?temperature?falls,?the?pointer?will?move?to?a?positive?value?of?zero?compensation?area.數(shù)據(jù)處理：溫度：Temperature?=?(	Temperature?High?|?Temperature?Low)/100??℃??例：Temperature?High=0xF6；Temperature?Low=0x05??????Temperature?=?0xF605/100?=?-25.55?℃?壓力：Pressure?=?(	Pressure?High?|?Pressure?Low)/1000??MPa??例：Pressure?High?=?0x12，Pressure?Low?=?0x34??????Pressure?=?0x1234/10000?=?0.4660?MPa?密度：Density?=?(	Density?High?|?Density?Low)/1000??MPa例：Density?High=0x56；Density?Low=0x78??????Density?=?0x5678/10000?=?2.2136MPa??返回的溫度、壓力、密度數(shù)據(jù)為2字節(jié)有符號整數(shù)。?密度以對應(yīng)20℃下的壓力P20表示，單位MPa.?壓力和密度用壓力表示，若轉(zhuǎn)化為相對壓力，減去當(dāng)?shù)卮髿鈮骸.電氣接口?Electrical?interface接線必須由經(jīng)過培訓(xùn)的人員操作?.接線分布和開關(guān)功能都在儀表型號牌上給出,并注明了接線柱和接地柱.規(guī)定供電電線必須考慮儀表的大電流需求量并符合?IEC227?或?IEC245?標(biāo)準(zhǔn).The?wirings?shall?be?performed?by?professionally?trained?personnel.?Wiring?distribution?and?switching?functions?are?displayed?on?the?instrument?type?plate?with?terminal?binding?posts?and?ground?pole?also?indicated.?The?specifications?of?power?line?must?allow?for?the?maximum?current?requirement?of?the?instrument?and?comply?with?IEC227?or?IEC245.安裝InstallationA．機械接口Mechanical?interface一般儀表常用的技術(shù)性規(guī)范這里也使用?(如:En837-2),旋轉(zhuǎn)安裝時所用的力不允許直接作用到表殼或接線盒上,而是通過合適的工具作用到扳手面上.Technical?codes?(e.g.,?En837-2)?applicable?to?ordinary?instrumentation?also?apply?here.?The?force?applied?for?rotation?installation?shall?not?directly?act?upon?the?instrument?housing?or?terminal?box?but?act?upon?the?wrenching?face?through?a?suitable?tool.訂貨說明Order?instructions型號/數(shù)量/量程/開關(guān)動作點/接口尺寸/其它特殊事項Model/quantity/measuring?range/switch?action?point/interface?dimensions/other?special?issues我們公司始終本著誠信經(jīng)營的原則，以“以誠為本，以質(zhì)取信”為宗旨，堅持“開拓、務(wù)實、守信”的企業(yè)精神，以誠摯的心，全方面的服務(wù)，為每一個客戶創(chuàng)造價值，讓客戶來的放心，用的舒心。與您攜手共進。
