Visible Setpoint, Adjustable Deadband, Hermetically Sealed Snap Switch, Weatherproof and Explosion-proof
SA1100系列膜片操作壓力開關在一個經濟外殼內防風雨和防爆。極其堅固的結構確保了化工、石油和工業工廠的卓越可靠性。新的設計還提供了3000psi (206 bar)的爆破壓力保護。滾動隔膜設計保持恒定的有效面積,以減少摩擦。這導致了最低的死區,低至全尺寸的5%。由于許多應用需要更高的死帶,SA1100包括一個單獨的調整,這是必要的。用于控制罐內液位的泵是一個典型的情況,這種特性很重要。設定值和死帶調整都受到保護,但在一個透明的聚碳酸酯窗口后清晰可見,并完全與電子元件隔離,以增加安全性。一個7/16"開口扳手是唯一需要改變設置的工具。提供了用于開關接線連接的端子,包括內部和外部的接地螺釘。標準外殼的耐候性符合NEMA標準1至4X和13;防爆等級:NEMA 7, I類,B、C、D組;可選結構增加排水,滿足NEMA 3R IP54標準。
