Pokcenser’s programmable digital pressure switch with display is an electronic device that is activated by the pressure of fluids, air, or gases reaching a predetermined level. These switches react or shift in response to the system’s pressure changes. Pressure switch components are connected to one or more contacts within the device. When adequate pressure is applied, a contact either closes or opens, based on the switch’s setup. Pressure switches are vital across numerous industries, including those utilizing compressed gas systems, HVAC systems, as well as instrumentation and pumping systems. There are digital pressure switch with npn output, and industrial digital pressure switch 4-20ma.
