差壓變送器可以精確地測(cè)量流量、液壓、低表壓、真空和比重。采用完全密封的 室作為感測(cè)元件，同時(shí)減少了靜壓(140MPa/cm2)誤差。設(shè)計(jì)精巧、防爆、量程和零點(diǎn)在外部調(diào)整等特點(diǎn)，使安裝、使用、調(diào)校都很簡(jiǎn)單。放大線路和接線端子置于彼此隔離的小室內(nèi)。因容積吸取量小于0.01立方英寸，可防止抽吸介液體，同時(shí)可不需為補(bǔ)償容積吸取量而增置的冷凝器和液位筒。采用鉭、哈氏合金(Hastelloy)和蒙耐爾(MONEL)合金等防腐材料，以適應(yīng)腐蝕性介質(zhì)的測(cè)量要求。采用固體元件和接插式印刷線路板，故障少，維修方便，減少了備品備件。　　本公司生產(chǎn)的1151K型電容式壓力、差壓變送器性能等同于1151型。DifferentialPressureTransmittercanaccuratelymeasuretheflow,liquidlevel,lowpressureofgauge,vacuumandspecificgravity.Itisadoptedtheentiresealingchamberassensingelement,decreasesthestaticpressure(140Mpa/cm3)errorsimultaneously.Itisverysimpletomount,useandcalibrateasthecharactersofelaboratedesign,explosiveproof,spanandzeroadjustedoutside.Theamplifiedcircuitandconnectingterminalarepositionedinthesmallisolatedchambereachother.Forthevolumeabsorbedislessthan0.01cubeinches,itmaypreventtoabsorbthemediumliquid,atthesametimeitisnotnecessarytoaddacoolerandliquidlevelbarreltocompensatethevolumeabsorbed.Itisusedthecorrosive-proofmaterialofTantalum,HastelloyandMoneletc.asappliedtothemeasuringofcorrosivemedium.Itisfewermalfunctions,easymaintenancetoreducingsparepartsasthesolidelementsandplug-incircuitboardareadopted.ThepropertyofModel1151KCapacitorPressure/DifferentialPressureTransmitterproducedinourcompanyisequaltothatofmodel151.
