Barksdale UDS7-BX Explosion Proof Electronic Pressure Switch
UDS7-BX系列防爆電子壓力開關
Barksdale的UDS7系列固態壓力開關提供三個分立元件（雙壓力開關、壓力傳感器和數字壓力表）組合成一個緊湊的封裝的便利性。可使用內置的用戶友好菜單輕松調整設定值，無需測試壓力。模擬傳感器輸出可從全可調范圍的25%擴展到125%。一個12位微處理器提供內置自診斷，允許開關延時和壓力循環高達每秒100次。這些裝置是按照IP65防護等級建造的。對于需要精確壓力控制和超長使用壽命的應用，UDS7系列是解決方案。Barksdale's UDS7 Series Solid State Pressure Switches offer the convenience of three discrete components (dual pressure switch, pressure transducer, and digital pressure gauge) combined into one compact package. Setpoints can be easily adjusted using a built-in, user-friendly menu without the need for test pressure. Analog transducer outputs are scalable from 25% to 125% of the full adjustable range. A 12-bit microprocessor provides built-in self diagnostics and allows for switch time delays and pressure cycling up to 100 times per second. These units are built to last and come standard with IP65 protection.For applications requiring precision pressure control and extremely long life, the UDS7 Series is the ideal solution.
