詳細介紹
Barksdale電子式壓力開關SW2000 Barksdale的SW2000電子式壓力開關擁有電子式開關的精度且價格經濟。SW2000可提供兩種不同配置:二個開關量或一個開關量帶有 一個4-20 mA模擬量輸出。通過使用鍵盤和用戶友好的菜單界面 可以方便地進行設定點和回差設定。模擬量輸出可縮放成從全量程的25%到100%。一個10-bit微處理器可自診斷并使開關時間延遲,壓力循環zui高次數可達每秒100次。開關擁有IP65標準防護等級并經久耐用。對于需要較低的價格進行精確壓力監控的應用,SW2000電子式壓力開關是一個*選擇。
特點:
帶有內部不銹鋼膜片的壓力控制器
高精度并且全量程可調節死區
二個固態觸點或一個固態觸點加一個4-20mA模擬量輸出
內置數字壓力顯示
通過鍵盤可實現全部設定
適合于快速循環(每秒100次)
