Can height sensor give an absolute reference

WebAug 1, 2024 · Pressure sensors are variously named according to their purpose, but the same technology may be used under different names. 1 Absolute pressure sensor. This sensor measures the pressure relative to a perfect vacuum. 2 Gauge pressure sensor. This sensor measures the pressure relative to atmospheric pressure. WebFor an absolute sensor, as the sensor increases its altitude, it will approach absolute zero, as expected. However, this can become problematic for a barometric range sensor as the reading will no longer be ~14.5 psi when vented to atmosphere. Instead, the local barometric pressure may read ~12.0 psi. However, this is not the case.
