STMicroelectronics introduces market-first waterproof MEMS pressure sensor with 10-year longevity for Industrial IoT expansion

24.08. 2023 | News

STMicroelectronics has introduced the market’s first MEMS water/liquid-proof absolute pressure sensor with a declared 10-year longevity program for the industrial market.

ST’s new ILPS28QSW sensor comes in a sealed, cylindrical, surface-mountable package. It features a ceramic substrate that provides high resistance to liquid permeability and a robust potting gel, proven in automotive applications, to protect the internal circuitry. The lid, made from high-grade surgical steel, is sealed with an o-ring and secured with epoxy adhesive. This unique package design ensures an ingress-protection rating of IP58 to withstand immersion in over one meter of water, certified according to IEC 60529 and ISO 20653. In addition, the sensor can sustain up to 10Bar over-pressure.

The ILPS28QSW provides absolute pressure readings, accurate to within 0.5hPa, with selectable full-scale range of 260-1260hPa and 260-4060hPa, and has a wide operating-temperature range, -40°C to 105°C (more info).
