Differentiaaldrukmetingen

Differentiaaldrukmetingen, or differential pressure measurements, involve determining the difference in pressure between two points. This fundamental measurement technique is crucial in a wide array of industrial and scientific applications.

The principle behind differential pressure measurement is straightforward. A sensor is placed at each of the two locations where pressure is to be measured. The device then calculates and displays the difference between these two pressure readings. This can be achieved using various sensor technologies, including diaphragm-based sensors, piezoresistive sensors, and capacitive sensors.

Common applications for differential pressure measurements include monitoring airflow in HVAC systems, detecting blockages in filters, measuring liquid levels in tanks, and determining flow rates in pipes using devices like orifice plates or venturi tubes. In the medical field, differential pressure is used to control airflow in operating rooms and isolation chambers to prevent the spread of contaminants.

The units of measurement for differential pressure are typically Pascals (Pa), pounds per square inch (psi), or inches of water column (inH2O), depending on the application and region. Accurate differential pressure measurement is essential for maintaining system efficiency, safety, and operational integrity across numerous industries.
