防爆感应式接点压力表
防爆感应式接点压力表YXGExplosion-proofInductiveElectricContactPressureGauge简介YXG系列防爆感应式接点压力表的接点形式为感应式接近开关,由于是非接触式接点,所以对供电系统不产生任何损耗,该仪表无电火花,使用寿命长,对测量精度影响小,不仅适用于某些有爆炸危险的场所,也特别适合设备频繁开关的场合使用。具有对工艺流程中的流体介质的压力参数进行检测、自动控制、自动报警等功能。YXG系列防爆感应式接点压力表是按GB3836.1《爆炸性气体环境用电气设备通用要求》和GB3836.4《爆炸性气体环境用电气设备本质安全型“i”》标准设计制造,并经国家相关部门进行防爆检验合格。YXG系列防爆感应式接点压力表应与P+F公司生产的安全栅配套使用,可构成本质安全防爆系统。此系统适用于1区和2区具有爆炸性气体的区域。BriefintroductionTheswitchofYXGseriesexplosion-proofinductivepressuregaugeisinductiveapproachform,becauseofnon-contact-type,ithavenotanyspoilagetothepowersupplysystem.Withoutelectricspark,longusinglife,littleimpactonthemeasurementaccuracy,itisnotonlyapplicabletocertaindangerousplaces,butalsosuitableforfrequentturnon/offoccasions.Ithasthetestingfunction,automaticcontrol,andautomaticwarningtotheliquidmedium.YXGseriesexplosion-proofinductivepressuregaugeisbasedonGB3836.1<therequestoftheelectricequipmentusedinexplosivegasenvironment>"andGB3836.4<safeexplosivegasenvironmentelectricalequipmentintrinsicallysafety-type"I">,andqualifiedtherelevantdepartmentsforthenationalexplosiontest.YXGseriesexplosion-proofinductivepressuregaugeshouldmatchwithsafetybarP+Ftobeasystemofintrinsicallysafeexplosion-proof.Thissystemisappliedto1areaand2areawithexplosivegas.工作原理YXG系列防爆感应式接点压力表的测量系统由弹簧管、机械传动机构、示值部件、感应式接点装置组成。弹簧管在被测压力作用下,产生弹性变形引起管端位移,其位移通过机械传动机构(连杆和机芯)进行放大,传递给示值部件,指针在刻度盘上指示出相应的压力值的同时,带动控制片的位置发生变化,当仪表指针与上限或下限设定指针重合时,控制片影响敏感元件的电磁场变化,使感应开关电气状态发生改变。可在设备达到设定压力时输出断(通)态信号,与外部设备用适当的电路连接后便能发出所需的报警信号或开、停机等控制压力的动作,将系统压力控制在所需范围内。OperatingprinciplesThemeasuresystemofYXGseriesexplosion-proofinductivecontactspressuregauge.Iscomposedbythebourdontube,mechanicaltransmissionsystem,value-showcomponents,inductivecontactdevice.Thedeformationofbourdontubeunderthemeasuringpressurecausespipes-displacement,andthedisplacementisenlargedbymechanicaltransmissionorganizations(connectingrodandmovement),whichistransferdtovalue-showcomponents.Thenthevalueofthepressureisindicatedandthepositionofcontrolpatchischanged.Whentheupanddownlimitssetbecometobecoinciding,thecontrolpatchaffectstheelectromagneticfieldchangestotransformthestateofelectricalswitches.Withtheoutputofturnon/offsignal,tosendthealarmorstart/stopmachineafterconnectingouterequipment,controlsystempressurewithinrequiredrange.主要技术指标仪表类型Types;YXG弹簧管标准型YPXG膜片标准型YXGS弹簧管密闭型YPXGS膜片密闭型YXGN弹簧管耐震型YPXGN膜片耐震型YXGBourdontubestandardtypeYPXGDiaphragmstandardtypeYXGBourdontubeobturationtypeYPXGSDiaphragmobturationtypeYXGNBourdontubevibration-prooftypeYPXGNDiaphragmvibration-prooftype仪表公称直径Diameter:φ100mm、φ160mm仪表结构形式Structure:①≥0.1MPa弹簧管型②<0.1MPa膜片型①≥0.1MpaBourdontubetype②<0.1MpaDiaphragmtype控制方法Control:电感式接近开关,输出方式见附表精确度等级Accuracy:φ100mm弹簧管型:(≥0.4MPa):1.0、1.5级(1.6级);(<0.4MPa及真空):1.5级(1.6级);φ160mm弹簧管型:(≥0.1MPa):1.0、1.6级(1.5级);(真空):1.6级(1.5级);φ100mm膜片型:2.5级;≥10kPa1.5级(1.6级)φ160mm膜片型:1.6级(1.5级)<10KPa2.5级φ100mmBourdontubetype:(≥0.4MPa):1.0%,1.5%(1.6%);(<0.4Mpa&vacuum=:1.5%(1.6%);φ160mmBourdontubetype:(≥0.1MPa):1.0%,1.6%;(vacuum)1.6%φ100mmDiaphragmtype:1.5%(1.6%),2.5%;φ160mmDiaphragmtype:1.6%;测量范围Range;①0~0.1至0~60MPa、-0.1~0各系列及任何相关正负压联程②4kPa~100kPa、-100kPa~0各系列及任何相关正负压联程①0-0.1to0-60Mpa,-0.1-0seriesandcompoundranges②4Kpa-100Kpa,-100Kpa-0seriesandcompoundranges电感式接近开关电气参数Inductanceapproachswitchelectricalparameter①额定电压:8VDC,安全使用电压<16VDC②工作电流:通态≥3mA,断态≤1mA,安全使用电流<52mA③开关频率:<5000Hz①Pressuregaugefixed:8VDC,Safevoltage<16VDC②Workingcurrent:Opening≥3Ma,Closed≤1Ma,Safecurrent<52mA③On/offfrequency<5000Hz工作环境温度Ambienttemperature:20℃~+60℃防爆等级Explosion-proofclass:ExibⅡCT6防爆合格证号码ThecodeofExplosion-proofCertificate:CE052074仪表防护等级Protectionclass:①标准型:IP54②密闭型、耐震型:IP65①Standardtype:IP54②Obturation&vibration-prooftype:IP65耐震型仪表填充液Liquidfillingofvibration-proofinstrument:专用仪表填充液SpecialInstrumentliquid电感式接近开关控制方法及接线示意Controlmethodandwiringdiagramofelectricinductiveapproachswitch接点代码Codeofcontacts接点功能识别编号接点数量指针须顺时针旋转开关功能批针在零位时开关示意图单上限831.21超过设定点时,控制片进入控制头,接点断开电路(常闭接点)单上限831.1超过设定时,控制片从控制头中出来,接点接通电路(常开接点)双上限831.222超过设定点时,接点1和接点2的控制片进入控制头接点1和接点2都断开电路双上限831.11超过设定点时,接点1和接点2的控制片都从控制头中出来接点1和接点2都接通电路常开上下限831.12超过设定点时,接点1的控制片从控制头中出来,接点接通电路接点2的控制片进入控制头,接点断开电路常闭上下限831.21超过设定点时,接点1的控制片进入控制头,接点断开电路接点2的控制片从控制头中出来,接点接通电路说明:1、定货时请按表中规定的开关功能给出相应的接点名称或编号。2、表中描述的开关功能晴示:仪表压力指针位于最小刻度值时所具有的开关功能,即压力指针从最小刻度值开始顺时针转动时的开关状态,当压力指针逆时针转动时,实现的开关功能相反。Notice:1.Whenordering,pleasespecifythenameorNo.ofcontactsreferringtothetable.2.Turnonandcutfunctiondetails:Thetableshowstheturnonandcutsituationsaspointermovesdeasil,andthefunctionisoppositewhilethepointermoveswiddershins.仪表公称直径φ100Diameterφ160YXG弹簧管标准型Bourdontube,StandardtypeYXGS弹簧管密闭型Bourdontube,ObturationtypeYXGN弹簧管耐震型Bourdontube,Vibration-prooftype仪表公称直径φ100Diameterφ160YPXG膜片标准型DiaphragmstandardtypeYPXGS膜片密闭型DiaphragmObturationtypeYPXGN膜片耐震型DiaphragmVibration-prooftype防爆感应式接点压力表YXG防爆感应式接点膜片压力表YPXG防爆感应式耐震接点压力表YXGN膜片耐震型防爆感应式接点压力表YPXGN本质安全防爆感应接点压力表)
