YZBK型壓力變送器選用美國擴散硅力敏元件測量氣體、液體或蒸氣壓力。其壓力信號轉(zhuǎn)換成4-20mA的標準電流信號，可實現(xiàn)生產(chǎn)過程自動化控制。廣泛用于化工、石油、發(fā)電廠、造紙、冶金等行業(yè)。 先進的電子線路采用恒流源激勵傳感器中的電橋及溫度補償技術，選用目前最優(yōu)良的專用集成電路，該變送器具有優(yōu)良的穩(wěn)定性，使用時不需預熱。全天候結構對振動、腐蝕、潮濕、干擾不敏感。智能型采用符合HART協(xié)議標準的電路、可通過272手操器現(xiàn)場進行參數(shù)調(diào)整。 Model YZBKPressureTransmitter isadopted force-sensing elementofdiffusionsiliconefromUSAtomeasuregas,liquidorsteampressure.Itspressuresignalsconvertstostandardcurrentsignalsof4-20mAthat canrealizetheautomaticcontrolofproductionprocessanditiswidelyusedintheindustryofchemical,petroleum,powerplant,paper,metallurgyetc. Theadvancedelectriccircuitisadoptedelectricbridgeintheexcitedsensorbyconstant-currentsourceandtechnologyoftemperaturecompensation,andthebestspecificICatpresentischosen .Thetransmitterhasagoodatabilitywithoutpreheatingbeforeusingit.
