YL-804Z digital pressure controller

The YL-804Z intelligent digital pressure controller is a high-precision intelligent controller that integrates pressure measurement, display, and control. It is mainly used for fully automatic control operation in various industries such as water treatment systems, electromechanical equipment automation, engineering machinery, and medical equipment.

The YL-804Z intelligent digital pressure controller realizes unmanned operation of equipment in the true sense, and is easy to set up. Its main functions include: achieving low pressure automatic start and high pressure automatic stop; Delay startup can be set to prevent frequent device startup; Automatic shutdown after no water, to prevent dry pumping; Automatic overpressure alarm and equipment shutdown; Password protection can be entered to prevent non professionals from modifying the set parameters
