A Differential Pressure Sensor is a critical device used to measure the difference in pressure between two points. These sensors are essential in applications that require precise pressure monitoring to maintain system efficiency, safety, and performance. Commonly used in HVAC systems, industrial process control, filtration, and fluid monitoring, differential pressure sensors provide real-time feedback on pressure changes, enabling users to maintain optimal conditions and protect equipment from damage due to excessive pressure or blockages.
What is a Differential Pressure Sensor?
A Differential Pressure Sensor measures the difference in pressure between two locations, typically across filters, pumps, or airflow ducts. The sensor has two ports that connect to the points where the pressure difference needs to be measured. By calculating this pressure difference, the sensor provides data that can indicate flow rate, filter condition, liquid level, or other critical parameters. Differential pressure sensors are available in various types, including piezoelectric, capacitive, and strain gauge sensors, each suited to different applications and environmental conditions.
