MPX5500D 概要
An integrated silicon pressure sensor is a monolithic semiconductor device in which a micromachined diaphragm deflects under applied pressure, changing embedded piezoresistive elements in a Wheatstone bridge. The MPX5500D belongs to the pressure sensor hierarchy: pressure transducer -> pressure sensor -> sensor IC -> signal conditioning IC -> semiconductor. Compared to resistive or ceramic capacitive sensors, monolithic silicon pressure sensors integrate amplification, calibration, and temperature compensation on the same die, eliminating external compensation circuitry and delivering near-direct ADC compatibility for microcontrollers.
Key features of the MPX5500D include a 0.2 V to 4.7 V analog output (0.5 V to 4.5 V typical usable span), 9 mV/kPa nominal sensitivity, 1 ms response time, ±1.5% accuracy over 0°C to 85°C, and ratiometric output operation from a single 4.75 V to 5.25 V supply. The on-chip ASIC performs laser-trimmed offset and span calibration, ensuring part-to-part interchangeability without external trim potentiometers. The device is also EMC-protected and qualified to typical industrial pressure-sensor environmental standards.
Typical applications include industrial process control, HVAC blower monitoring, water pressure monitoring, gas metering, and pneumatic system feedback in factory automation. Its differential (not gauge or absolute) reference makes it well-suited to measuring pressure drop across orifices, filters, or pumps in flow-derived systems. The 5 V ratiometric output connects directly to the ADC input of 5 V microcontrollers.
When designing with this device, decouple the Vs pin with a 100 nF ceramic capacitor placed within 5 mm of the lead. Apply pressure only via the silicone gel-protected side ports to avoid damaging the diaphragm, and avoid PCB stress on the SIP body that could couple mechanical strain into the sensor element.

主な用途
MPX5500D の用途: 6 件s: Industrial Pneumatic System Pressure Monitoring, HVAC Duct and Filter Pressure Drop Sensing, Water and Gas Pressure Monitoring, Medical and Laboratory Instrument Pressure Sensing, Engine and Vehicle System Pressure Monitoring, Portable Compressor and Pump Control.
Industrial Pneumatic System Pressure Monitoring
The MPX5500D's 0-500 kPa range and 9 mV/kPa sensitivity align precisely with industrial compressed air pressures typically regulated at 600-800 kPa (87-116 psi), allowing direct monitoring of regulated shop-air rails without mechanical pressure scaling. Placed in the supply manifold it feeds a 5 V microcontroller ADC ratiometric to the same rail, giving 0.2 V at no load and 4.7 V at full-scale pressure; the 1 ms response time tracks regulator dynamics faster than typical pneumatic actuators, while ±1.5% accuracy over 0°C to 85°C covers factory-floor temperature variation. Unlike gauge mechanical gauges, the on-chip conditioned output eliminates bourdon-tube drift and the silicone-gel isolation lets non-corrosive dry air contact the diaphragm directly, simplifying the pneumatic interface.

HVAC Duct and Filter Pressure Drop Sensing
Building HVAC systems need continuous filter-loading monitoring to schedule maintenance, and the MPX5500D measures differential pressure across a filter or fan coil in the typical 50-500 kPa working span with comfortable margin. Mounted across the filter, its two ports see ambient and post-filter pressures; the 0.2-4.7 V ratiometric swing connects to a 5 V HVAC controller ADC, where the 9 mV/kPa scale resolves small differential rises that signal filter clogging. The integrated temperature compensation ensures the reading does not drift with duct air temperature, and unlike a manometer the electronics pack into a control-board enclosure. Estimated: a 0-500 kPa unit at 10% filter loading produces roughly 0.5 V, at 50% loading about 2.4 V, and at alarm threshold about 3.6 V.
おすすめ
Water and Gas Pressure Monitoring
Municipal and process water systems typically operate at 100-700 kPa line pressure, squarely inside the MPX5500D's 0-500 kPa differential range, making it suitable for booster pump feedback and leak detection on non-aggressive liquid lines. Plumbed with the high-pressure port at the process side and the low-pressure port at atmosphere through a small reference tube, the sensor outputs a linear 0.2-4.7 V signal for direct ADC sampling. Compared with ceramic capacitive sensors, the silicon piezoresistive die delivers faster 1 ms response, better repeatability, and integrated temperature compensation without external EEPROM; designers should still add a media isolation diaphragm where water quality is uncertain, as the bare silicon is not corrosion-isolated.
おすすめ
Medical and Laboratory Instrument Pressure Sensing
Bench-top autoclaves, sterilizers, and analytical instruments need reliable 0-500 kPa pressure feedback for cycle validation, and the MPX5500D's ±1.5% accuracy meets laboratory instrumentation needs over 0°C to 85°C. Located inside the pressure chamber, the SIP module is mounted with one port vented to atmosphere and the other exposed to the chamber, allowing direct differential measurement of gauge pressure during the sterilization cycle. The 1 ms response time captures pressure ramps, and the integrated ASIC removes the calibration burden per device. Estimated: a 200 kPa readback yields roughly 2.0 V on a 5 V supply, well inside the linear transfer region so instrument designers can subtract the offset in firmware.
おすすめ
Engine and Vehicle System Pressure Monitoring
Engine intake and oil gallery monitoring demands temperature-stable analog pressure transduction, and the MPX5500D's 0-500 kPa range covers boost pressures, transmission line pressure, and hydraulic accumulator pressures in light commercial equipment. Wired to a 5 V ECU ADC with ratiometric reference, the sensor's 9 mV/kPa slope translates boost fluctuations directly to engine-management firmware without external amplification. The integrated temperature compensation retains accuracy across engine bay thermal cycling, and the gel-protected front ports tolerate non-corrosive fluids and air. Estimated: a 250 kPa boost reading produces about 2.45 V, providing the resolution needed for closed-loop boost control algorithms in turbocharged engine conversions.
おすすめ
Portable Compressor and Pump Control
Portable air compressors and hydraulic pumps benefit from analog 0-500 kPa pressure feedback into 5 V battery-powered microcontrollers, and the MPX5500D's integrated signal conditioning eliminates the op-amp front end that discrete bridge sensors require. Power-cycled by a load switch, the sensor's typical 10 mA draw can be gated off in standby to extend battery life on cordless compressor units; the 1 ms response time is fast enough to detect tank-fill completion by watching the slope change as the regulator cuts in. Compared with electromechanical pressure switches, the ratiometric analog output provides variable hysteresis in firmware rather than a single fixed cut-out point.

設計ノート
Estimated: decoupling the Vcc pin with a 100 nF ceramic capacitor placed within 5 mm of the MPX5500D SIP leads suppresses supply noise and stabilizes the ratiometric output. The sensor draws approximately 10 mA typical, so a low-dropout regulator with adequate headroom (e.g., 5.0 V LDO from a 7 V+ source) is preferred over a switching regulator whose ripple would alias into the pressure reading without adequate LC filtering at the sensor pin.
Do not apply pressure to the back-side or any non-port surface of the MPX5500D; only the silicone-gel-protected front ports should see media or air pressure, otherwise the glass bond can crack. Solder stress relief on the through-hole leads is also critical: avoid rigid PCB strain on the SIP body, as the package transfers mechanical strain directly into the silicon die and corrupts the reading; use a cable-tied strain relief or a rubber boot if the sensor is connected via tubing.
For best ADC accuracy, derive the analog reference of the microcontroller ADC from the same 5 V rail that powers the MPX5500D so the conversion is ratiometric to Vcc and cancels supply noise. Estimated: with a 10-bit ADC over a 5 V range, each LSB is about 4.9 mV, or roughly 0.54 kPa at the 9 mV/kPa slope; a 12-bit ADC raises that to roughly 0.13 kPa resolution, sufficient for industrial pneumatic and HVAC monitoring without external amplification.
