SW2000

Description

Barksdale's SW2000 Electronic Pressure Switch offers the accuracy of an electronic pressure switch in an economical package. The SW2000 is available in two different configurations: as a dual pressure switch or as a single switch with integrated 4-20 mA analog output. Setpoints and deadband are easily adjusted by using the keypad and user-friendly menu. Analog transducer outputs are scalable from 25% to 100% of the full adjustable range. A 10-bit microprocessor provides built-in self diagnostics and allows for switch time delays and pressure cycling up to 100 times per second. Built to last, these switches come standard with IP65 protection. For applications requiring precision pressure monitoring and control at an affordable price, a SW2000 Electronic Pressure Switch is the ideal solution.
