Honeywell Differential Pressure Sensor Surface Mount, 6-Pin, ±0.25% Accuracy, 3.3V - 5V, HSCMRRD005NDAA5

Honeywell HSCMRRD005NDAA5 is a highly accurate differential pressure sensor designed for embedded and board-mounted applications. Featuring a surface mount (SMT) configuration with six pins, it is ideal for integration into compact electronic systems and provides precise measurement of pressure differences between two ports.

This sensor operates from a single 3.3V or 5V supply, offering flexibility for various circuit designs. It delivers either a ratiometric analog output or a 12 - 14 bit digital output compatible with I2C or SPI protocols, making it easy to interface with controllers and microprocessors. With ±0.25% full scale accuracy, the HSCMRRD005NDAA5 ensures reliable, high-precision readings and reduces the need for software correction.

The maximum operating pressure of 34.5 kPa allows the sensor to handle low-pressure measurements effectively. Its dual radial barbed port design simplifies tubing connections and is intended for use with non-corrosive, non-ionic gases, and - for specified higher pressure ranges - certain compatible liquids. All calibration and temperature compensation for offset, sensitivity, and non-linearity are performed onboard across a compensated range of 0°C to 50°C, with operation extending up to 85°C.

Update rates reach up to 2kHz, supporting rapid monitoring in applications such as airflow sensing in respiratory equipment, clogged filter detection in HVAC systems, laboratory gas flow instrumentation, medical ventilators, and low-pressure leak detection in medical devices. The sensor is manufactured to meet ISO 9001 standards and features moisture sensitivity level 1 for solder reflow, ensuring quality and reliable performance in industrial and laboratory environments.

The compact form factor, robust surface mount package, and highly accurate response make this sensor an excellent choice for engineers designing advanced electronics, industrial instrumentation, and medical equipment. Typical use cases include industrial automation, laboratory analysis equipment, HVAC and environmental monitoring, and medical diagnostics.
