YL-813 digital pressure switch

YL-813 Digital Pressure Switch is a high-precision digital pressure switch that integrates pressure measurement, display, and control functions into an intelligent pressure switch and pressure controller. It can completely replace the electric contact pressure gauge and can be used as a high-pressure pressure switch. This pressure switch has two sets of relay outputs, two normally open and normally closed outputs, and can achieve two controller functions. It can also achieve functions such as two sets of normally open, two sets of normally closed, low point closed, high point disconnected, low point disconnected, and high point closed. This product has the advantages of high precision, small hysteresis, fast response, stable and reliable performance, easy operation, and easy and flexible installation. It is a high-tech product used by microcomputer technology for pressure automatic control. Widely used for pressure control and automation control of gases and liquids in chemical, mechanical, hydraulic, power and other systems.
