Sensortechnics’ HDI sensors measure absolute, differential or gauge pressures in various ranges from 10mbar up to 5bar. The HDI series features 3V supply versions which are suitable for battery powered applications. They perform precision digital signal conditioning and achieve high accuracy with a total error band better than ±0.5% over the temperature range of 0 to +85 °C.
The HDI series provides a digital interface via the I²C bus protocol plus analogue outputs from 0.5 - 4.5V. The sensors are intended to be used with air and non-corrosive gases and offer various unidirectional, bidirectional or barometric calibrations as well as different accuracy classes.
Miniature SMT and DIP housings allow for space-saving PCB-mounting and maximum OEM design flexibility. All HDI pressure sensors can be modified according to customer requirements, with respect to pressure range, resolution, accuracy and internal digital settings.
