Applications
The SSCSNBN001PDAA5 is used in medical respiratory equipment such as ventilators and CPAP machines to measure differential pressure across flow restrictors and precisely calculate patient airflow rates. Its temperature-compensated analog output makes it well-suited for HVAC duct pressure monitoring, filter-clog detection, and variable-air-volume control systems operating in commercial buildings. Industrial process engineers also use it in laboratory instruments and pneumatic control panels where a 1 psi range and ratiometric signal simplify integration with low-cost microcontroller ADCs.

Frequently Asked Questions
How accurate is the SSCSNBN001PDAA5 across its 0°C to 50°C operating range for a medical ventilator design?
The SSCSNBN001PDAA5 is factory-calibrated and temperature-compensated, providing a total error band typically within ±2% of full-scale 1 psi (6.9 kPa) over the 0°C to 50°C range, which meets the accuracy requirements of most medical respiratory flow measurement applications without additional software compensation.
For an HVAC filter-clog monitor, what output signal does the SSCSNBN001PDAA5 provide and how does it connect to a microcontroller ADC?
The sensor delivers a ratiometric analog voltage output that scales proportionally with the supply voltage, typically 10% to 90% of VDD across the 0 to 1 psi differential pressure range, so a 3.3V or 5V microcontroller ADC can directly digitize the signal without an instrumentation amplifier or external bridge circuit.
How does the 4-pin SIP package of the SSCSNBN001PDAA5 facilitate integration into a compact respiratory flow module?
The 4-pin SIP form factor allows vertical through-hole mounting on a PCB with a footprint under 10 mm x 10 mm, and the dual port stubs on the sensor body accept standard 3/32-inch medical-grade silicone tubing for differential pressure taps, simplifying pneumatic connection in miniature CPAP and spirometry modules.
What media can the SSCSNBN001PDAA5 measure and are there any gas compatibility restrictions for industrial applications?
The SSCSNBN001PDAA5 is designed for dry, non-condensing gas media including air and inert gases; it is not rated for liquids or corrosive gases, so industrial users measuring aggressive atmospheres should select a Honeywell model with wetted stainless-steel internals instead of the standard polymer porting used in this 1 psi device.
