The HSCMRRN002ND2A3 is a TruStability® HSC Series piezoresistive silicon pressure sensor designed for differential pressure measurement. This sensor operates on a 3.3 Vdc supply and provides a digital I²C output with address 0x28. It is configured for a differential pressure range of ±2 inH₂O and is housed in a surface-mount (SMT) package with dual radial barbed ports on the same side. The device is fully calibrated and temperature compensated over a range of 0 °C to 50 °C for offset, sensitivity, and non-linearity, and is intended for use with dry gases only. Its high accuracy, stability, and small size make it suitable for various medical and industrial applications such as airflow monitors, HVAC VAV control, and respiratory equipment.
