Sensortechnics’ HDI sensors measure absolute, differential or gage pressures in various ranges from 10 mbar up to 5 bar (4 inch H2O up to 150 psi). The HDI series features 3 V supply versions which are suitable for battery powered applications, e.g. in portable or handheld devices. HDI pressure sensors perform precision digital signal conditioning and achieve ultra high accuracies with a Total Error Band (TEB) better than ±0.5 percentFSS over a temperature range of 0…+85 °C (32…185 °F). The series provides digital interfaces with I²C bus protocol and analog 0.5 … 4.5 V output signals at the same time therefore allowing customers to build up a redundancy functionality for safety critical applications.
