The MP3V5010DP is a differential pressure sensor with an operating pressure of 1.45 PSI (10 kPa) and a maximum overpressure rating of 10.88 PSI (75 kPa). The analog output spans 0.1 V to 3.1 V, scaling linearly from zero to full-scale pressure — so at 0 PSID the output sits near 0.1 V, and at 1.45 PSID it reaches 3.1 V. That 3 V span gives you about 2.07 V/PSI of resolution before your ADC's own noise floor. Accuracy is specified at ±5% of full-scale span. For a 1.45 PSI sensor, that translates to roughly ±0.073 PSI of uncertainty — adequate for airflow monitoring or filter-clog detection, but worth noting if your application requires better than 5% point accuracy across temperature.
Temperature range and compensation — where this sensor works
That covers automotive under-hood, industrial oven exhaust, and outdoor telecom cabinet environments without derating. The compensation circuitry keeps the offset and span drift within the ±5% accuracy band across the full temperature window — no external temperature correction needed in firmware. The analog output is ratiometric to the supply — if your ADC reference is the same supply rail, the measurement stays accurate despite small supply variations.
Package and port configuration — board-fit details
Housed in an 8-BSOP package (0.475" body width, 12.06 mm length) with dual barbed ports on the same side. The ports accept 0.13" (3.3 mm) ID tubing — push the tubing over the barb and it seals without a clamp for pressures up to the 10.88 PSI maximum. Surface-mount mounting means the sensor sits flat on the PCB — no through-hole alignment. The dual-port same-side layout lets you route both pressure lines to one edge of the board, simplifying the manifold or tubing harness.
