Overview

The HSCDRRN001PD2A3 is a high-accuracy, board-mount differential pressure sensor from the Honeywell TruStability HSC Series. It is designed to measure pressure differences across two ports within a range of +/-1 PSI (+/-6.89 kPa) and provides a digital I2C output. This sensor is fully compensated and amplified, providing a 14-bit resolution internal ADC with a total error band as low as +/-0.25 percent.

Why Choose This Part

This sensor eliminates the need for external signal conditioning circuitry by integrating an ASIC for temperature compensation and calibration. The radial barbed port design allows for easy and secure tubing connections in space-constrained board layouts. Operating on a 3.3V supply with a low 3.1mA typical current draw, it is well-suited for energy-efficient industrial and medical instrumentation.

Applications

HVAC VAV Control
Precise measurement of airflow across filters or within ducts for Variable Air Volume systems.
Medical Ventilators
Monitoring differential pressure in respiratory equipment to ensure accurate patient air delivery.
Pneumatic Controls
Detecting pressure drops in industrial pneumatic lines to monitor system health and efficiency.
Gas Flow Instrumentation
Measuring low-pressure gas flow in analytical laboratory equipment or environmental monitors.

Getting Started

To integrate this sensor, connect the SCL and SDA pins to an I2C master with 2.2k to 10k ohm pull-up resistors. The sensor operates at a 3.3V logic level and provides a 14-bit digital value that can be converted to pressure using the transfer functions defined in the Honeywell HSC series datasheet. Ensure the dual ports are connected to the system using 0.08 inch (1.93mm) ID tubing for optimal performance.
