Dwyer 1823-2 is a low differential pressure switch designed for general industrial service applications. It can operate in temperatures ranging from -30 to 180°F and has a pressure limit of 10 psig. The switch features a single-pole double-throw configuration with a set point adjustment screw. It has 3 screw type electrical connections and is suitable for use with air and non-combustible, compatible gases. The diaphragm should be positioned vertically, but other orientations can be discussed with the factory. The switch is rated for 15 A @ 120-480 VAC, 60 Hz and can handle resistive loads up to 1/4 HP @ 250 VAC. The repeatability is ±2%. Wetted material and other details should be confirmed with the factory.
