The Differential Pressure Gauge provides a continuous way to monitor pressure drop across the aftercooler so the user can detect changes that affect airflow and overall system behavior. It supports smoother operation by revealing shifts caused by recirculated crankcase fumes, helping the user maintain stable conditions. The gauge helps reduce unexpected performance issues by showing early signs of restrictions that require attention. It offers a clearer approach than using two separate gauges by combining the readings into one display, simplifying checks during service tasks.Attributes:• Provided with a range of 0-101 cm (0-40 in) of water.• Helps the user detect changes caused by airflow restriction.• Supports steady observation during crankcase fumes recirculation.Applications: The Differential Pressure Gauge functions in the aftercooler monitoring area to track pressure drop across the core, supporting steady airflow assessment and dependable system performance during service checks.
