电阻远传压力表YTZPressuregaugewithresistancetran***itter简介电阻远传压力表通过仪表内部的滑动电阻发送器把被测值以电量值传至远离测量点的二次仪表上，以实现集中检测和远距离控制，此外本仪表能够同时就地指示压力，（便于现场工艺检查）。本仪表还可以与膜片隔离器（隔离体）连接，制成电阻远传隔膜压力表，可测量腐蚀性较强、黏度大、易结晶介质的压力。BRIEFINTRODUCTIONThroughthebuilt-inadjustableresistancetran***itter,840seriesgaugescantran***itthemeasuredvaluestothesecondarygaugesfarfromthesiteandachievetheconcentratedexaminationandremotecontrol.Meanwhile,thegaugescanindicatethepressurevalue(forspottechnicalinspection).Itcanbeconnectedwithdeaphragminsulator,makingpressuregaugewithresistancetran***itter,Designedforstrongcorrosive,viscousandeasytobecrystallographicmedia.工作原理仪表由一个弹簧管压力表和一个滑线电阻式传感器组成，当被测压力变化时，弹簧管端产生位移，一方面通过传动系统使指针在度盘上指示相应压力，另一方面带动电刷在电阻上滑行，使被测压力值的变化转换为电阻值的变化，并传至二次仪表上指示相应的压力。OperatingPrincipleThegaugeisformedbyabourdontubepressuregaugeandaadjustableresistancetran***itter.Whenthepressureischanging,thetubeenddeformed,andthepointeristoshowthepressurevaluethroughthedrivingsystem,atthesametime,thebrushisslippingontheresistancetotran***itthepressurevaluestoresistantvalues,whichistran***itedtothesecondarygaugetoshowtherelativepressurevalue.YTZ主要技术参数测量介质：对铜合金无腐蚀作用气体或液体（可与多类化学密封隔离器配接在各种腐蚀性环境使用）安装方式：径向直接安装连接螺纹M20×1.5（或其他螺纹尺寸）精度等级：1.5级外径：150mm测量范围：正压：0.1MPa⋯⋯60MPa；负压：-0.1～0MPa,-0.1～2.4MPa。工作条件：环境温度：-40～70℃相对湿度：≤85%工作压力：使用温度偏离20&plu***n;5℃时，其温度附加误差不大于0.4%/10℃滑线电阻发送器技术数据：起始电阻：6～20Ω满度电阻：340～400Ω接线端外加电阻：≤6V外壳材质：压铸合金铝接头材质：铜合金波登管：铜合金表盘：铝，白地黑字指针：铝，黑色玻璃：普通玻璃YTZSpecificati***Medium:Gasorliquid,whicedoesn’tcorrodecopperalloy(couldbeusedincorrosionenvironmentsconnectedchemicalseals.)Mounting:BottomconnectiondirectthreadM20×1.5orotherAccuracy:1.5%Diameter:150mmRange:Positivepressure0.1MPa⋯⋯60MPa；Negativepressure-0.1～0MPa,-0.1～2.4MPaWorkingcondition:Ambienttemperature:-40～70℃Relativehumidity:≤85%Workingpressure:Whenworkingtemperaturedeviatesfrom20&plu***n;5℃.Theadditionaltemperatureerrorshallnotbemorethan0.4%/10℃Technicaldataofresistancetram***itterStartresistance:6～20ΩFullscaleresistance:340～400ΩConnectionendadditionalresistance:≤6VCase:CastaluminiumalloySocketmaterial:CopperalloyBourdontube:copperalloyDialaluminum:whitewithblackdivisionPointer:Aluminium,blackGlass:Windowglass接线示意图WIRINGDIAGRAM产品详细资料请点击：电阻远传压力表YTZ.pdf电阻远传压力表YTZ电阻远传隔膜压力表YTZP远传压力表YTZ)
