Digital Pressure Switch
Product Overview
Section titled “Product Overview”The Digital Pressure Switch is an intelligent digital pressure switch that combines pressure measurement, display and control in one device. It supports two normally open or normally closed alarm points, two-channel high and low pressure control, one-touch zeroing and switching between three display units.
The circuit design emphasizes stability for automation field conditions, including magnetic interference resistance, surge protection and reverse connection protection. The shell and connectors are made of 304 stainless steel, making the switch suitable for automation production lines and hydraulic systems.
