MPX10GS Présentation
Background knowledge: A pressure sensor is a transducer that converts an applied pressure force into a measurable electrical signal. Within the broader transducer taxonomy, the MPX10GS sits in the piezoresistive pressure sensor family, which uses the piezoresistive effect in silicon — a change in electrical resistance when mechanical stress is applied. This family sits under the hierarchy pressure sensor -> transducer -> sensor -> electronic component. The MPX10GS is uncompensated, meaning the manufacturer does not calibrate offset, span, or temperature drift; designers must add external op-amps and calibration routines to reach medical or industrial accuracy.
Key features of the MPX10GS include 35 mV full-scale span (typical), an operating pressure range from 0 to 1.45 PSI (0 to 10 kPa), vented gauge reference (G suffix on the package style), a 4-SIP through-hole package, and a typical operating temperature range that supports industrial and consumer environments. The device requires only a single 3V DC excitation source and produces a Wheatstone-bridge differential output that scales linearly with pressure, allowing straightforward signal conditioning with instrumentation amplifiers such as the INA125 or INA126.
From an architectural standpoint, the MPX10GS die is laser-trimmed to provide tight linearity across its specified pressure range, and the vented gauge configuration means the back side of the die is referenced to ambient pressure through the port tube, simplifying absolute-pressure measurements in atmospheric applications. Designers can implement temperature compensation, offset null, and span calibration using low-cost operational amplifiers or a dedicated mixed-signal microcontroller ADC.
Typical applications include low-pressure pneumatic control, HVAC differential-pressure monitoring, medical respiratory and airflow instruments, altimeters and barometric estimation, fluid-level sensing via pressure, and consumer fitness or wearables requiring basic airflow sensing. Industrial 4 mA to 20 mA loop-transmitter front ends also use the MPX10GS as the raw sensing element.
When designing with the MPX10GS, plan for external amplification — the 35 mV full-scale span is too low to drive an ADC directly. Add a low-offset, low-noise instrumentation amplifier and a stable 3V excitation regulator. Shield the analog traces from digital switching noise to preserve the small mV-level signal integrity.

Applications typiques
MPX10GS convient pour 6 applications: Low-Pressure Pneumatic Control, HVAC Differential-Pressure Monitoring, Medical Respiratory and Airflow Instruments, Altimeter and Barometric Estimation, Fluid Level Sensing via Pressure, Consumer Fitness and Wearable Airflow.
Low-Pressure Pneumatic Control
The MPX10GS is well-suited to industrial low-pressure pneumatic control where 0 to 10 kPa (0 to 1.45 PSI) covers the typical vacuum and low-pressure line range. Its 35 mV full-scale span at 3V excitation gives a 3.5 mV/kPa sensitivity, which is straightforward to amplify with a low-cost INA125 instrumentation amplifier. Placed on a vacuum manifold or downstream of a pressure regulator, the MPX10GS detects clogged filters, leak conditions, and regulator drift. Designers must add a stable 3V reference (e.g., REF3033) and a high-CMRR instrumentation amp to achieve the 1 percent FS accuracy required by process-control loops.
Recommandé
HVAC Differential-Pressure Monitoring
In HVAC systems, the MPX10GS monitors filter differential pressure and fan airflow across ductwork. Its 0 to 10 kPa vented-gauge range is perfectly matched to clean-room and building-automation filter status sensing, where a clogged filter typically produces 250 Pa to 750 Pa differential. The uncompensated output requires a one-time trim of offset and span in firmware, but the silicon piezoresistive bridge delivers better than 0.5 percent linearity. Pair the MPX10GS with a 4-20 mA loop transmitter for legacy BMS integration, or with an I2C ADC for direct microcontroller interfacing.
Recommandé
Medical Respiratory and Airflow Instruments
The MPX10GS is used in low-cost spirometers, peak-flow meters, and CPAP pressure monitors where 0 to 10 kPa covers inspiratory and expiratory pressure swings. Its 35 mV full-scale span is well within the resolution of medical-grade 24-bit sigma-delta ADCs, and the small 4-SIP side-port tube mates with standard pneumatic fittings used in breathing circuits. Because the sensor is uncompensated, the host firmware must apply temperature compensation and a calibration check at startup. For FDA-grade medical designs with on-chip temperature compensation, consider the MPX5010 family instead.
Recommandé
Altimeter and Barometric Estimation
The MPX10GS provides a low-cost 0 to 10 kPa vented-gauge measurement suitable for drone altimeters, weather-station barometric estimation, and recreational-grade altitude reporting. One kPa change corresponds to roughly 8.4 meters of altitude at sea level, so the 3.5 mV/kPa sensitivity yields 4.2 mV per meter of climb when properly amplified. For accurate absolute altitude, the host must subtract local sea-level pressure; for relative altitude (used in drones), the vented gauge configuration makes the calculation straightforward. Shield the analog traces from motor PWM noise to preserve the small mV-level signal.
Recommandé
Fluid Level Sensing via Pressure
The MPX10GS detects fluid level by sensing hydrostatic pressure at the bottom of a tank or reservoir. For water at 9.81 kPa per meter of depth, the 0 to 10 kPa range maps to approximately 1 meter of water column, making the MPX10GS ideal for shallow tanks, drip-tray monitoring, and small chemical reservoirs. The vented-gauge configuration automatically compensates for atmospheric pressure changes, so a sealed tank is not required. Designers should use food-grade tubing between the sensor and the fluid to isolate the silicon die from corrosive media.
Recommandé
Consumer Fitness and Wearable Airflow
The MPX10GS is used in consumer fitness devices such as peak-flow meters, handheld spirometers, and bicycle turbo-trainers that measure breathing or wind pressure. Its small 4-SIP package and 3 mA typical excitation current suit battery-powered designs, and the 0 to 10 kPa range covers the typical 0.5 to 8 kPa breathing pressure envelope. Pair the sensor with a low-power microcontroller (e.g., MSP430 or Nordic nRF52) and a coin-cell battery for a multi-year operating life. Calibration at production can be as simple as a single-point atmospheric reference.

Notes de conception
Estimated: at 3V excitation the MPX10GS bridge draws approximately 6 mA. Use a low-noise LDO such as the LP2985 or REF3033 to provide a stable 3V reference, since supply ripple couples directly into the mV-level bridge output. Add 10 uF bulk and 100 nF ceramic bypass capacitors directly at the VCC and GND pins to suppress high-frequency noise from upstream switching converters.
The 35 mV full-scale output is small enough that PCB trace routing matters significantly. Route the VOUT+ and VOUT- traces as a differential pair with matched length, keep them away from digital switching nodes, and use a ground guard trace between the analog bridge output and any nearby MCU GPIO. Place the instrumentation amplifier within 20 mm of the sensor output pins to minimize common-mode pickup before amplification.
A frequent design mistake is connecting the MPX10GS directly to a microcontroller ADC without external amplification. The 35 mV span is below the resolution of most 10-bit and 12-bit ADCs at 3.3V reference. Always use a low-offset instrumentation amplifier (e.g., INA125 with 250 uV max offset) and a 16-bit or higher ADC for usable resolution. Also, ensure the vent port on the side of the package remains unobstructed — do not pot or conformal-coat over it.
Although the MPX10GS is uncompensated, the bridge resistance drifts approximately 0.3 percent per degree C. For applications requiring better than 5 percent FS accuracy over -10 C to +60 C, add an on-board temperature sensor (e.g., TMP36) and apply a 3-point calibration lookup in firmware. For high-accuracy industrial designs, choose the compensated MPX5050 family instead.
