overview：

PSWI5581 is an intelligent pressure switch integrating pressure measurement, display and control. This product uses advanced industrial-grade MCU as the core and high-quality sensor, under the premise of ensuring accuracy, rapid response and good electromagnetic compatibility of the pressure switch are achieved through careful design and adjustment. Because of its good media compatibility, the pressure switch can be widely used in various industrial control sites such as pumps, hydraulic and pneumatic equipment, etc.

PSWI5581 intelligent pressure switch visualizes the process pressure and switch contact status through switch output, analog output and a display screen, it can provide multiple output configurations according to different applications. The switch has functions such as delay setting, range zoom, manual reset and peak value display,etc. With special design and structure, it can be installed vertically, horizontally or rack mounting. 180°rotation of display information and 330°rotation of instrument body can ensure that display screen faces the operator, self-luminous OLED display is clear and easy to read, it can also support Modbus communication function.
