LHD pressure sensors

The LHD differential low pressure sensors are based on thermal flow measurement of gas through two micro-flow channels integrated within the silicon sensor chip. Two thermal sensing elements allow for wide measurement range with a typical resolution at low pressures of 0.05 Pa. An on-board microcontroller with accurate 24-bit ADC provides signal processing including stitching of the response of two sensing elements, linearization and temperature compensation.

Typical applications include medical devices, HVAC and instrumentation. Specialized features that are ideal for mass-flow and volume-flow applications.
