產品簡介 YXDH-100不銹鋼電接點壓力表采用彈簧管作為測壓敏感元件,主要用于測量具有腐蝕性環境或測量介質具有腐蝕性的氣體及液體壓力,并通過儀表指針的觸點與設定指針的觸點相接通(斷開)控制系統中電路的開關,以達到自動控制和發報警信號的目的。 本儀表可安裝3 個或4 個接點,其開關點的位置可通過表玻璃上的調節旋鈕設定。 本儀表可與各類膜片隔離器相連接,制成隔膜電接點壓力表,用于測量腐蝕性強、粘度大、易結晶介質的壓力。 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. 主要技術參數 儀表類型 普通型、耐震型(充油) 指示儀表直徑 φ 100mm; 指示精度 ± 1.5%、± 2.5%; 設定精度 ± 4% ; 測量范圍 正壓:0-0.4MPa ??0-60MPa;及任何相關正負壓聯程; 接點形式 3個或 4個接點; 接點材質 ≥ 110V銀鎳合金, ≤ 36V黃金 zui高工作電壓 380V•AC或 220V•DC; zui大電流 1A; 觸點功率 30VA; 儀表內機 SUS316; 外殼材料 SUS304; 儀表玻璃 有機玻璃、安全型雙層玻璃; 電接口 M20 × 1.5,6+PE(接地)端,徑向安裝在儀表右側,軸向安裝在儀表背后; 外殼防護等級 普通型:IP54 ,耐震型:IP65; 環境溫度 普通型:-40~+70℃;耐震型:-20~+60℃; 耐震型填充液 儀表填充液; 連接尺寸 螺紋連接 M20 × 1.5、或約定的特殊要求; 法蘭連接(按相關標準或約定的特殊要求)。 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) 接點功能 Functions of contacts 注: ①當指針逆時針轉動時,實現相反的開關功能。 ②對于四接點儀表,由于設計原因,所有四個接點不能重疊在一個設定值上,前三個可以重疊的接點與第四個接點所成夾角≥ 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. 型號標示 Model remark 接點代碼 Code of cantacts | 接點功能識別編號 Code title | 接點數量 Quantity | 指針順時針旋轉開關功能 rotating switch function of deasil pointer | 示意圖 Sketchmap | 112 = 下下上限 down down up limits | 821.221 | 3 | 超過設定點時,接點1 斷開電路 接點2 斷開電路 接點3 接通電路 up limits over the setpoint, contact 1 cuts contact 2 cuts, contact 3 turns on | 121 = 下上下限 down down up limits | 821.212 | 超過設定點時,接點1 斷開電路 over the setpoint, contact 1 cuts 接點2 接通電路 接點3 斷開電路 contact 2 turns on, contact 3 cuts | 2222 = 四上限 four up limits | 821.1111 | 4 | 超過設定點時,接點1 接通電路 over the setpoin, contact 1turns on 接點2 接通電路 接點3 接通電路 contact2turns on,contact 3turns on 接點4 接通電路contact 4 turns on | 1212 = 下上下上限 down up down up limits | 821.2121 | 超過設定點時,接點1 斷開電路 over the setpoint, contact 1 cuts 接點2 接通電路 接點3 斷開電路 contact 2 turns on, contact 3 cuts 接點4 接通電路contact 4 turns on | 訂貨時: 1.請給出接點名稱及型號。2.如所需要接點功能表中未列出,請在訂貨時詳細說明。 when ordering:1.supple with name and model of contacts. 2.specify the resuest if it is not involed in the table. | 注: ①當指針逆時針轉動時,實現相反的開關功能。 ②對于四接點儀表,由于設計原因,所有四個接點不 標準型 Standard style: YXDH-100 (YXC-100H) 耐震型 Vibration-proof style: YXDHN-100 (YXCN-100H) :多設定點電接點壓力表. 不銹鋼多接點壓力表YXDH-100 耐震防腐多接點壓力表YXDHN-150 全鋼耐震多接點壓力表YXDHN-160 耐震多接點電接點壓力表 多接點壓力表YXDH |
