Here's the complete spec. HIROSE Electric Engineering Specification — HSCDRRN001ND2A5 Manufacturer: Honeywell Sensing and Productivity Solutions Device Family: TruStability HSC Series General Description The HSCDRRN001ND2A5 is a high-accuracy, fully compensated and amplified differential pressure sensor manufactured by Honeywell, belonging to the TruStability HSC Series of board-mount pressure sensing devices. The device is built around a piezoresistive silicon sensing element housed within a ceramic package, combining a mature and proven sensing principle with advanced on-chip signal conditioning that makes the device ready for direct interfacing with a host microcontroller or processor without requiring extensive external analog signal processing circuitry. The defining characteristic of the TruStability HSC series, and of this device in particular, is its fully calibrated and temperature-compensated output, achieved through an integrated application-specific integrated circuit that corrects for sensor offset, sensitivity drift, temperature effects, and pressure nonlinearity across the device's rated operating range. This level of factory compensation allows the device to maintain its specified accuracy across the full compensated temperature range without requiring individual board-level calibration, significantly simplifying the design and production process for equipment that relies on precise low-pressure measurement. This particular configuration uses a digital I²C output interface, communicating pressure readings as high-resolution digital data words over a standard two-wire bus using a fixed I²C device address. This digital output makes it highly compatible with modern embedded system architectures where analog-to-digital conversion resources may be limited or where noise immunity and data integrity over longer trace runs are priorities. The device offers both high resolution and high accuracy within a tight total error band, making it suitable for applications where small differential pressure differences must be resolved reliably over time and temperature variation. The sensor is configured as a differential pressure measurement device, meaning it produces an output proportional to the difference in pressure between its two pneumatic ports rather than to absolute or gauge pressure relative to atmosphere. This makes it particularly well suited to airflow measurement, filter condition monitoring, liquid level detection, spirometry and respiratory measurement, HVAC duct pressure sensing, and other applications where the pressure difference across two points in a system is the relevant physical quantity. The device is housed in a through-hole dual in-line package with two radial barbed pneumatic port fittings located on the same side of the package body, allowing small-bore flexible tubing to be connected directly to each port without requiring additional adapter fittings. The barbed port design provides a secure, friction-held tube connection that resists accidental disconnection during normal handling and operation. The package is designed for standard through-hole PCB mounting, and the device is intended for use with non-corrosive, non-ionic dry gases only, consistent with the silicon and ceramic wetted materials used in its construction.
