YL-814E digital pressure switch

YL-814E is an intelligent digital pressure switch with a 100mm stainless steel casing, integrating pressure measurement, display, and control into an economical digital pressure switch. This series of pressure switches can set two normally open and normally closed alarm points, and can also achieve two high and low pressure control. In addition, it has multiple functions such as one key reset and switching between three display units. The design of the circuit emphasizes stability and fully considers the actual situation of the automation site. It has strong resistance to dry magnetic interference, anti surge protection, and anti reverse connection protection.
