The HDI series performs precision digital signal conditioning to achieve ultra high total accuracies. An internal ASIC compensates sensor offset, temperature effects, and non-linearity to allow for an excellent Total Error Band better than ±0.5% FSS. The pressure sensors provide digital interfaces with I2C bus protocol and analog 0.5/4.5 V output signals. The HDI series offers absolute, differential, and gage pressure measurement in various ranges from 10 mbar up to 10 bar (4? H2O up to 150 psi). The sensors feature unidirectional, bidirectional, or barometric calibrations and are intended to be used with air and non-corrosive gases.
