Dwyer Instruments 1823-1 is a differential pressure switch in the 18231 Series 1800 family, designed to sense a defined pressure difference and actuate an electrical circuit when the set point is reached. Model 1823-1 is part of the 18231 Series 1800 Pressure Differential Switch and carries a 480 VAC electrical rating. This device is used in systems where monitoring differential pressure is required and a switch output is triggered when the specified differential is reached.
