Description
The Dwyer Instruments A3000-00 Photohelic Swtch 0-.25 UL/CS is a pressure switch and gauge combo intended for use in HVAC systems and other industrial applications. This multifunctional instrument facilitates the monitoring and regulation of air pressure or other suitable gas pressure in a closed-loop system. A diaphragm in the pressure switch component reacts to variations in pressure. A diaphragm that senses pressure between 0 and 0.25 inches of water column (in. H2O) and uses that pressure to activate or deactivate an electrical switch. By using this switching action, you can regulate a number of system operations, like turning on or off fans, alarms, or other equipment in response to changes in pressure.
