Veris Industries PWRLX05S006A Wet Diffuser Transducer 0-250 PSI W/6' Cable

The Veris Industries PWRLX05S006A is a wet differential pressure switch intended for use in HVAC equipment such as air handling units and fan coils. A 6-foot wire is included for simple installation. By monitoring the pressure differential across a wet coil—typically a heat exchanger where warm air transfers heat to cool, water-laden airflow—this switch plays a critical part in preventing water damage. The air pressure entering and leaving the wet coil is measured by the switch. A possible problem, such as a blocked coil or limited water flow, is indicated when the pressure differential drops below a predetermined threshold.
