Pressure sensors are a key component in the monitoring and validation of steam temperature and other conditions in autoclaves commonly used to sterilize medical and dental equipment. Nominal conditions are around 2.1bar, 134°C (maximum pressure is about 3.8 bar/55 psi) steam from pure distilled water. Some of the requirements for pressure sensors are typical of most of today’s equipment calling for smaller form factor and cost-effective solutions. Autoclaves have additional application-specific needs for pressure sensors in that they must deliver high accuracy, be able to support elevated operating temperatures, feature high pressure capabilities, and offer harsh media compatibility.
