Switch2000 (EN) SW2000 - Barksdale Việt Nam

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. For applications requiring precision pressure monitoring and control at an affordable price, a SW2000 Electronic Pressure Switch is the ideal solution.
