100 不锈钢多接点压力表YXDH/YXDHN YXC-100H Stainless Steel contact pressure gauge (many contacts style) 产品简介 YXDH-100不锈钢电接点压力表采用弹簧管作为测压敏感元件，主要用于测量具有腐蚀性环境或测量介质具有腐蚀性的气体及液体压力，并通过仪表指针的触点与设定指针的触点相接通（断开）控制系统中电路的开关，以达到自动控制和发报警信号的目的。 本仪表可安装3 个或4 个接点，其开关点的位置可通过表玻璃上的调节旋钮设定。 本仪表可与各类膜片隔离器相连接，制成隔膜电接点压力表，用于测量腐蚀性强、粘度大、易结晶介质的压力。 PRODUCT  OVERVIEW YXDH-100 Stainless Steel Electric contact pressure gauge adopts Bourdon tube as pressureelement, mainly apply to the corrosion environment or measuring the pressure of the corrosion gas and liquid. The pointer of instrument will make contacts turn on or cut with the  contacts of set fingr, causing the cut and turn-on of control system for the purpose of  automatic control and alarm. The pressure gauge could be installed 3 or 4 contacts, and the switch point could be set using the adjustable button on the window. The pressure gauge could combine with many kind of diaphragms to crank out diaphragm electric contact pressure gauge which is fit to measure the pressure of corrosive, viscous and crystallographic medium.   主要技术参数 仪表类型     普通型、耐震型（充油） 指示仪表直径 φ 100mm； 指示     ± 1.5%、± 2.5%； 设定     ± 4% ； 测量范围     正压：0-0.4MPa ⋯⋯0-60MPa；及任何相关正负压联程； 接点形式     3个或 4个接点； 接点材质     ≥ 110V银镍合金， ≤ 36V黄金 工作电压 380V•AC或 220V•DC； 电流     1A； 触点功率     30VA； 仪表内机     SUS316； 外壳材料     SUS304； 仪表玻璃     有机玻璃、安全型双层玻璃； 电接口       M20 × 1.5，6+PE（接地）端，径向安装在仪表右侧，轴向安装在仪表背后； 外壳防护等级 普通型：IP54 ，耐震型：IP65； 环境温度     普通型：-40～+70℃；耐震型：-20～+60℃； 耐震型填充液 仪表专用填充液； 连接尺寸     螺纹连接 M20 × 1.5、或约定的特殊要求； 法兰连接（按相关标准或约定的特殊要求）。   Specifications Type: Standard type, vibration-proof type (oil filled) Diameter: φ 100mm Accuracy: φ 100mm, ± 1.5%, ± 2.5% Set accuracy: ± 4%; Range: Plus pressure 0-0.4Mpa to 0-60Mpa and other  combine ranges Contact points: 3 or 4 Maximum working voltage: 380V.AC or 220 V.AC Maximum current: 1A Contact power: 30VA Movement: SUS316 Case material: SUS304 Windows: Organic glass, Safety glass (double deck) Electric connection: M20 × 1.5, 6+PE(contact the earth) Bottom connection, on the right side of the gauge Back connection, at the back of thegauge Case protection: Standard type: IP54  Vibration-proof: IP65 Environment temperature: Standard type: -40-+70℃ Vibration-proof type: -20-+60℃ Liquid filling for vibration-proof style oil: Filling liquid for special instrument Connection size: Thread connection M20 × 1.5, Or special requirement     Flanged connection (by relative standardsor promised special requirement) 接点功能 Functions of contacts

订货时： 1.请给出接点名称及型号。2.如所需要接点功能表中未列出，请在订货时详细说明。 when ordering:1.supple with name and model of contacts. 2.specify the resuest if it is not involed in the table.

  注： ①当指针逆时针转动时，实现相反的开关功能。 ②对于四接点仪表，由于设计原因，所有四个接点不能重叠在一个设定值上，前三个可以重叠的接点与第四个接点所成夹角≥ 30° Note: ① When anticlocknise, it performs opposite function. ② For four contauts instrument, these contacts can’t be overlapped on the same set value due to the design. There  exists over 30° between former 3 contacts and the fourth contact.       型号标示 Model remark 标准型 Standard style: YXDH-100 (YXC-100H) 耐震型 Vibration-proof style: YXDHN-100 (YXCN-100H)   不锈钢多接点压力表YXDH-100 耐震防腐多接点压力表YXDHN-150 全钢耐震多接点压力表YXDHN-160 耐震多接点电接点压力表 多接点压力表YXDH
