Industrial pressure sensor with dual full-scale and Qvar


Dual full-scale selectable pressure range and Qvar technology in an industrial MEMS pressure sensor

The ILPS22QS is an ultra-compact piezoresistive absolute pressure sensor for industrial applications that behaves as a digital output barometer. It is the first industrial ST pressure sensor supporting a selectable dual full-scale pressure range up to 1260 hPa or 4060 hPa.

Thanks to its full-molded package consisting of 6 small vent holes, a suspended membrane, and a silicon cap, it is ideal for measuring air pressure and for smart filter maintenance in industrial applications involving extended temperature ranges up to 105°C.

The ILPS22QS embeds analog hub sensing used to implement the Qvar technology, which is critical for water leakage detection.
