产品介绍：

YTP系列膜片压力表 YTP Series Theca Pressure Meter Series 压力表证书(http://www.chinawanda.net/default.asp?a_c_id=236&a_id=16489)   简介       膜片压力表适用于测量具有一定腐蚀性、非凝固或非结晶的各种流体介体的压力或真空，它是解决测量高温粘稠压力的有效途径。       耐腐蚀性能取决于膜片材料。可根据测量介质对耐腐蚀性能的不同要求而选用不同材质的膜片。       不锈钢膜片压力表的导压系统和外壳等均为不锈钢，有较强的耐腐蚀性能。       耐震膜片压力表内部充灌阻尼液和配套缓冲装置，具有良好的耐震性能。在被测介质的压力有强烈脉冲变化或压力冲击和在生产工艺中经常突然卸荷的场合，以及环境震动较大的场所中，耐震膜片压力表都能稳定进行测量。 Brief introduction       Diaphragm pressure meters are suitable for measuring pressure or negative pressure of various liquid mediums that is corrosive non-crystalloid and non-concretionary.Itis officient path to slove measure high temperature viscidity pressure.       Corrosion resistance depends on diaphragm material. Choosing diaphragm material is decided by different performance of corrosion resistant that the measured medium required.       In stainless steel diaphragm pressure meters stainless steel material is adopted in manufacturing pressure leading system and its crust so this sort of meters possesses better corrosion-resistant performance.       Shockproof diaphragm pressure meter is filled with damping liquid inside and assembled with buffering device owning good performance of shock proof. This sort of meters can measure pressure steadily in locations where the pressure of medium changes intensely and pressure shock exists or pressure is released suddenly in the course of manufacturing or working environment shock largely.   构成示意图 Internal structure     结构原理       仪表由测量系统（包括法兰接头、波纹膜片）、传动指示机构（包括连杆、齿轮传动机构、指针和度盘）和外壳（包括表壳和罩圈）等组成。仪表外壳为防溅结构，具有较好的密性，故能保护其内部机构免受污秽浸入。       仪表的作用原理是基于弹性元件（测量系统上的膜片）变形。在被测介质的压力作用下，迫使膜片产生相应的弹性变形——位移，借助顶杆使经传动机构工作，由固定于齿轮上的指针将被测值在度盘上指示出来。 Configuration principle       This sort of meters is composed of measuring system (including flange joint ripple diaphragm) driving indicating machine (including connecting bar gear wheel driving machine pointer and meter dial) and crust (including meter shell and cover circle). Meter crust is designed into antispatter structure with better sealing performance so it can prevent dirtiness from immerging into the inner structure.       Operation principle of the meters is d on distortion of elastic components (diaphragm used in measuring system). Under the action of pressure of measured medium diaphragm will produce corresponding elastic distortion－displacement. The displacement is enlarged by driving machine in virtue of connecting bar thus measured pressure value will be shown up gradually by pointer fixed on gear wheel.     主要技术参数 度：2.5级 使用环境温度：-40~+70℃ 表壳内不充油  5℃~55℃  表壳内充甘油                     -25℃~55℃  表壳内充硅油  相对湿度不大于90% 温度影响：使用温度偏离20±5℃时，其温度附加误差不大于  0.04%/℃ 工作位置：垂直安装 外壳防护等级：IP64 Principal technical parameters   Accuracy:  2.5 grades emperature of applicable circumstance: -40~+70℃ with no petrol filled inside the crust 5℃~55℃ with glycerin filled inside the crust Temperature affect: (with temperature departure of 20±5℃ the additional error shall be less than 0.04%/℃ Working condition: :uprighness connection Defend grade of crust: IP64 型号表示  Model designations       标记示例： YPFN-150B-MF  产品电脑编码：0420060430       不锈钢耐震膜片压力表（法兰连接）。产品电脑编码详见《膜片压力系列仪表选型指南》。       Mark example: YPFN-150B-MF  Electronic code:0420060430 Stainless steel shock proof diaphragm pressure meter(flange connection).Production computer coding please see："Guide  for type selection of theca series instruments and meters     外形尺寸 External dimension 型号规格 Types and specifications   材质说明 Material deion 膜片压力系列仪表选型指南 Diaphragm pressure meter series selection guidelines   订货须知 Ordering instructions       订货时须注明：产品电脑编码、型号、名称、度、测量范围。如特殊要求，请注明技术要求。       Ordering instructions: The product computer code types names accuracy grades and measuring ranges .must be clearly noted.
