General description
First Sensor HDI sensors offer precision pressure measurement from 10 mbar up to 5 bar. 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 (TEB) better than ±0.5 %FSS. The pressure sensors provide digital interfaces with I²C bus protocol as well as analog output signals. Optional 3 V supply voltage versions and special low power devices make the HDI series ideal for battery powered applications, e.g. in portable or handheld devices. Miniature SMT housings allow for space-saving PCB-mounting and maximum OEM design flexibility.
Size without nipples and pins (approx.) 12 x 15 x 7 mm
The LDE differential low pressure sensors are based on thermal flow measurement of gas through a micro-flow channel integrated within the sensor chip. The innovative LDE technology features superior sensitivity especially for ultra low pressures. The extremely low gas flow through the sensor ensures high immunity to dust contamination, humidity and long tubing compared to other flow-based pressure sensors. Miniature SMT and DIP housings allow for space-saving PCB-mounting.
Typical applications include medical devices, HVAC and instrumentation.
