Barksdale UDS7-BX Explosion Proof Electronic Pressure Switch
UDS7-BX系列防爆电子压力开关
Barksdale的UDS7系列固态压力开关提供三个分立元件（双压力开关、压力传感器和数字压力表）组合成一个紧凑的封装的便利性。可使用内置的用户友好菜单轻松调整设定值，无需测试压力。模拟传感器输出可从全可调范围的25%扩展到125%。一个12位微处理器提供内置自诊断，允许开关延时和压力循环高达每秒100次。这些装置是按照IP65防护等级建造的。对于需要精确压力控制和超长使用寿命的应用，UDS7系列是解决方案。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.
