In practice, the measurement of flow data in HVAC (heating, ventilation, air-conditioning, cooling) systems asks a lot of the measurement technology used. In addition to temperature fluctuations, sensors are also exposed to a lot of dust.

Today, innovative sensor technologies provide you with the right pressure sensor for every measuring task. Not only can you choose between relative, absolute and differential pressure sensors that work with different reference values, modern pressure sensors also allow you to choose between different measuring principles based on different physical effects. Piezoelectric and piezoresistive effects are mainly used in modern pressure sensors. 

Measuring inclination, acceleration and vibration in a technical application requires high-precision inertial sensors: tiny MEMS (Micro Electromechanical Systems) based on single crystal silicon sensor elements and the latest micromechanical manufacturing processes. 

HVAC systems require high-sensitivity pressure sensors to minimize energy costs and meet regulatory requirements.

Silicon photomultipliers (SiPMs) are innovative optical sensors for the detection of ultra-low light levels down to single photons.

The choice of the right measuring method is decisive for your pressure measurement task. We explain the difference between absolute, gage and differential pressure and give application examples.

We explain the physical background, operating principle and construction of non-consumptive zirconium dioxide oxygen sensors
