Able to measure absolute, differential, or gauge pressures in ranges from 10 mbar up to 5 bar, the HDI series of pressure sensors features versions that can work from a 3-Vdc supply, suiting them for use in battery-powered portable or handheld devices. The sensors perform precise digital signal conditioning and achieve accuracies with a total error band (TEB) better than ±0.5% FSS over a of 0° to 85°C range.
The sensors are intended for use with air and noncorrosive gases, and versions offer various unidirectional, bidirectional, or barometric calibrations as well as different accuracies. The units have an I2C port for digital operation as well as a 0.5 to 4.5-V output; both ports can operate simultaneously, so designers can build in redundancy for safety-critical applications.
The sensor’s miniature SMT and DIP housings save board space and provide design flexibility. In addition to being available from stock in a wide selection of configurations as well as 5-V versions, sensors can be modified with respect to pressure range, resolution, accuracy, and internal digital settings to meet customer requirements.
