UDS7

Description

Barksdale's UDS7 Series Electronic 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.
