Front Differential Pressure Sensor Boss

The front differential pressure sensor boss is a precision mounting interface welded onto pipes or filter housings to secure a differential pressure sensor. Typically manufactured from stainless steel or carbon steel, it features two threaded ports (high and low pressure) and machined sealing surfaces for leak-proof connections. This boss ensures correct sensor orientation and accurate measurement of pressure drops across filters, particulate traps, or orifices. Common applications include diesel particulate filter systems, HVAC circuits, and industrial filtration units. Proper alignment and welding techniques prevent false readings caused by flow disturbances or pressure imbalances.
