High accuracy pressure sensors for battery powered applications

Sensortechnics’ HDI sensors measure absolute, differential or gage pressures in various ranges from 10 mbar up to 5 bar. The HDI series features 3V supply versions which are ideally suitable for battery powered applications, such as 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% FSS over a temperature range of 0…+85°C.

The HDI series provides digital interfaces with I²C bus protocol and analogue 0.5 … 4.5V output signals at the same time therefore allowing customers to build up a redundancy functionality for safety critical applications. 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. A wide selection of sensor configurations are available from Sensortechnics. All HDI pressure sensors can be modified according to customer specific requirements, e.g. with respect to pressure range, resolution, accuracy and internal digital settings.

Due to the wide selection of different sensor configurations Sensortechnics is able to offer customers the best suitable sensor with an ideal cost/performance ratio. Typical applications of the HDI pressure sensors include medical devices, instrumentation, environmental controls and HVAC.
