Air pressure decreases from point zero (= sea level, at 1013 mbar) with increasing altitude. Atmospheric pressure changes, at constant temperature, with approximately 1 mbar / 8 m. But it's trickier than that. You can find more on this topic in our description "Precise altitude measurement with a pressure sensor module". For a quick result, [...]
Here he comes: the new pressure sensor AMS 6916 with analog output for all pressure types and different pressure ranges from 0 ... 5 mbar to 0 ... 1.2 bar. Industrial applications e.g. Filter control or level measurement, as well as respiratory control or gas flow measurements in medical technology are among the numerous fields [...]
These differential pressure sensors for extremely low pressures of up to 3 mbar are used in medical technology and filter control. OEM pressure sensor SM9235 has a digital I2C output signal and an optional 3.3-V or 5-V supply. The AMSYS sensor is calibrated and compensated for and its accuracy can be increased by offset calibration. Low pressure [...]
When measuring pressure, it’s not only important to have the right pressure sensor to hand; sometimes there are also difficult problems to be overcome. One example is where the controller cannot be directly installed at the point of measurement. Here, a combination of DPC-100 (controller) and an external pressure sensor in the DPH-100 series provides [...]
Sleep apnea is a common disease that affects many people around the world. The remedy is a device known as CPAP (Continuous Positive Airway Pressure). These include sensors that guarantee controlled breathing support with defined airflow, air temperature and humidity. This article explains how the pressure sensors work.
