MPXM2010GS - 10kPa Vented Gauge Pressure Sensor | NXP/STMicro
MPN： MPXM2010GS ✓ 啟用中MPXM2010GS 概覽
A pressure sensor is a transducer that converts an applied pressure into a proportional electrical signal. Piezoresistive sensors, the family to which the MPXM2010GS belongs, exploit the change of silicon resistivity under mechanical strain. This class of sensor sits hierarchically below MEMS sensors and above general-purpose transducers in the sensor taxonomy, offering higher accuracy than ceramic capacitive cells but lower bandwidth than resonant or optical alternatives. Within pressure-sensor terminology, "vented gauge" means the back side of the diaphragm is open to ambient atmosphere through a vent port, so the output reflects differential pressure relative to local barometric conditions.
The MPXM2010GS series provides nominal 2.5 mV/kPa sensitivity, very low pressure hysteresis, and excellent long-term stability over its -40 °C to +125 °C operating range. Its vented-gauge topology makes it especially attractive for applications that must reject package-stress and reference local atmospheric pressure. The uncompensated output voltage span remains consistent across temperature thanks to the on-chip thin-film compensation network, simplifying downstream signal conditioning.
Typical applications include medical respiration monitors, HVAC air-flow measurement, weather-station barometric sensing, appliance pressure feedback, and industrial process control loops. The vented-gauge configuration with tube-port inlet suits enclosed module designs where reference-to-ambient accuracy matters more than fully-sealed absolute measurement.
Designers should excite the bridge from a low-noise, low-drift 10 V reference and amplify the millivolt-level output with an instrumentation amplifier such as the INA128 or AD620. PCB layout should keep ground loops away from the sensor body, and the vent tube must remain unobstructed to preserve gauge accuracy.

典型應用
MPXM2010GS 適用於 6 應用s: Medical Respiration Monitoring, HVAC Airflow and Duct Pressure Sensing, Barometric Weather Stations, Appliance Pressure Feedback (Coffee Machines, Washers), Industrial Process Control Loops, Portable Spirometer and Peak-Flow Meter.
Medical Respiration Monitoring
The MPXM2010GS's 10 kPa full-scale range is well matched to airway pressure monitoring in CPAP, ventilator, and spirometer circuits, where typical airway pressures are 0 to 5 kPa. Its 2.5 mV/kPa sensitivity and on-chip temperature compensation yield a stable 25 mV output span at 10 V excitation, which can be amplified by an instrumentation amplifier such as the INA128 for ADC digitization. The vented-gauge topology references local atmospheric pressure and rejects package stress, giving consistent breath-to-breath readings. Low 6 mA bridge current keeps battery drain minimal in portable respiration monitors.
推薦
HVAC Airflow and Duct Pressure Sensing
Building-automation systems use the MPXM2010GS to measure low differential pressures across filters, coils, and variable-air-volume boxes, where typical pressures range 0 to 1.5 kPa. The 10 kPa range gives comfortable headroom for transient spikes during damper movement, while the vented-gauge configuration tracks atmospheric pressure changes that influence building airflow. The 5-SMD top-port package accepts a 0.12" tube that can be routed to standard duct probes. Its -40 °C to +125 °C operating range covers rooftop and basement HVAC environments.
推薦
Barometric Weather Stations
The MPXM2010GS's 10 kPa range covers sea-level barometric pressures (roughly 98 to 105 kPa absolute, but measured here as ~0 kPa gauge relative to a vented reference) for portable weather instruments. Its on-chip temperature compensation holds sensitivity within a few percent across outdoor temperature swings, so simple polynomial correction in firmware suffices for sub-hectopascal accuracy. The low 6 mA supply current suits solar-powered weather stations that must run for months on battery. Pair the sensor with a low-power MCU like the MSP430 for unattended field deployments.

Appliance Pressure Feedback (Coffee Machines, Washers)
Consumer appliances use the MPXM2010GS to monitor water-line or steam pressure in espresso machines, steam ovens, and washing-machine inlet valves. The 10 kPa range covers typical domestic water pressures (0 to 4 bar = 500 kPa is too high, so use the part in low-pressure brew-head sensing where pressures stay below 1 bar). The SMD package simplifies automated assembly lines, and the on-chip temperature compensation reduces calibration time per unit. Output amplification with a single op-amp delivers a 0 to 5 V signal compatible with most appliance microcontrollers.
推薦
Industrial Process Control Loops
Process-control PLCs use the MPXM2010GS for low-pressure tank-level measurement, cleanroom differential sensing, and pneumatic control feedback where pressures remain below 10 kPa. The 25 mV span at 10 V excitation provides adequate resolution after amplification for setpoint control of valves and pumps. The vented-gauge topology automatically compensates for altitude and barometric drift, which is essential in facilities that span multiple elevations. Industrial-grade -40 °C to +125 °C operation tolerates outdoor panel installations and unconditioned control cabinets.
推薦
Portable Spirometer and Peak-Flow Meter
Handheld pulmonary function testers use the MPXM2010GS to sense airflow pressure through a flow-head orifice, where peak flow rates correspond to pressures of 0.5 to 5 kPa. The 25 mV full-scale output at 10 V excitation provides enough signal headroom for a single op-amp gain stage before ADC sampling, reducing BOM cost in disposable and reusable medical designs. The compact 5-SMD package fits inside a handheld enclosure, and its low 6 mA supply current extends battery life across thousands of tests. Pair the sensor with a Bluetooth Low Energy MCU for wireless data transfer to a phone.

設計說明
Estimated: The MPXM2010GS bridge draws approximately 6 mA at 10 V excitation, dissipating 60 mW in the sensor itself. A low-noise 10 V LDO such as the LT3042 or REF5025 followed by a 0.1 µF ceramic decoupling capacitor placed within 5 mm of the Vs+ pin is recommended. Avoid switching regulators directly feeding the bridge - their residual ripple couples directly into the millivolt output and degrades effective resolution by 10 to 20 percent unless heavily filtered.
Bridge output is a 0 to 25 mV differential signal that is highly susceptible to common-mode noise and thermoelectric offsets. Use a true instrumentation amplifier (INA128, AD620) with >100 dB CMRR at the sensor bandwidth. Route Vs+ and Vs- as a tightly coupled twisted pair or differential stripline; even 50/60 Hz pickup on a single-ended run can saturate the gain stage. Add 10 kHz low-pass RC anti-aliasing before the ADC.
Do not block the vent port on the back of the package - the sensor needs atmospheric reference to give correct gauge readings. Solder paste and conformal coating can seal the vent and cause large zero-point drift. Use a foam gasket or open cavity under the package. Also avoid mechanical stress on the package from screw bosses or housing clips, since piezoresistive sensors are sensitive to PCB flex; mount the device on a stress-isolated island if the enclosure is subject to clamping forces.
Although the MPXM2010GS includes on-chip temperature compensation, the bridge self-heating at 10 V/6 mA is only ~60 mW and does not require special thermal management. However, if you operate the part at the 16 V maximum, self-heating increases to ~150 mW and may shift the zero by a few millivolts after power-on. Allow a 5-minute warm-up before calibration, or use the part in pulsed excitation mode for highest accuracy.
