WASHER SOLUTIONS WS12133 Barksdale Pressure Switch – 12133

The Barksdale 12133 is a pressure switch, a component used in medical equipment to monitor or control fluid pressure in gas and liquid systems. It is typically installed in the gas delivery, vacuum, or pneumatic subsystems of patient monitors, ventilators, anesthesia machines, and related clinical devices. The 12133 is identified by its model number and Barksdale manufacturer designation, and it functions as a simple electromechanical sensor that triggers an electrical contact when pressure rises or falls past a set threshold.
