Differential pressure sensors, crucial in various engineering applications, measure the pressure difference between two points in a system. These sensors enable precise monitoring of pressure variances, aiding in the assessment of flow rates, fluid levels, or filter conditions. Commonly used in HVAC systems, automotive applications, filtration systems and fuel tank leveling, they ensure optimal performance by detecting changes in pressure across devices. Employing a diaphragm or other sensitive mechanisms, these sensors convert pressure differentials into electrical signals, facilitating accurate data acquisition. Engineers rely on these instruments for real-time insights into fluid dynamics, enhancing system efficiency and reliability.
