MPX10GP - 10kPa Uncompensated Pressure Sensor | STMicroelectronics
MPN: MPX10GP ✓ فعالMPX10GP جائزہ
A piezoresistive pressure sensor is a MEMS device in which implanted piezoresistors on a silicon diaphragm change resistance when mechanical strain from applied pressure alters the band structure of the silicon. The MPX10GP belongs to the silicon pressure sensor family, which sits within transducers, which in turn sit within the broader sensor hierarchy used for physical-parameter measurement. This uncompensated architecture is the lowest-cost tier of the family; downstream amplification, offset correction, and temperature drift correction must be implemented externally with op-amps and reference sources.
Key features of the MPX10GP include an operating pressure range of 0 to 10 kPa (approximately 0 to 1.45 PSI), a full-scale span of 35 mV typical at 3 V DC excitation, and a vented gauge reference that allows absolute atmospheric pressure measurement through a single port. The 4-SIP through-hole package simplifies hand prototyping and breadboard use, while the integrated tube inlet accepts flexible pneumatic tubing for airflow or liquid-level sensing applications.
Technically, the sensor is built on a single-element piezoresistive Wheatstone bridge with on-chip trimming, with a sensitivity around 3.5 mV/kPa at 3 V supply. Because the device is uncompensated, designers must characterize offset, span, and temperature coefficient in their own test fixtures and apply corrections in software or analog networks to achieve production-grade accuracy.
Typical applications include HVAC air-flow measurement, medical respiratory equipment, water-level tank sensing, barometric reference design, and industrial process control where custom external compensation is acceptable in exchange for low unit cost. Designers building precision instrumentation typically select a higher-tier compensated MPX series part instead.
When designing with this device, ensure a stable low-noise 3 V excitation source and use instrumentation amplifiers with low offset drift. The uncompensated nature means PCB layout should keep analog signal traces short and shielded from digital switching noise.

عام استعمالات
MPX10GP کے لیے موزوں ہے 6 ایپلیکیشنs: HVAC Airflow Measurement, Medical Respiratory Monitoring, Water Level / Tank Sensing, Barometric Reference Design, Industrial Process Control, Consumer Appliance Pressure Switch.
HVAC Airflow Measurement
The MPX10GP's 0 to 10 kPa range and 3.5 mV/kPa sensitivity at 3 V excitation align well with HVAC duct static-pressure sensing, where typical pressures are well below 10 kPa. The 4-SIP module with male tube port accepts flexible pneumatic tubing directly from the duct, and the uncompensated bridge output lets the design engineer apply linearization in software to correct for temperature drift. Compared to a fully compensated MPX5500, the MPX10GP saves cost at the expense of requiring external calibration circuitry on the analog front end.

Medical Respiratory Monitoring
In medical airflow and respiratory monitoring equipment, the MPX10GP's small form factor and 0 to 10 kPa vented gauge range match low-pressure inspiratory and expiratory flow sensing. The uncompensated 35 mV full-scale span at 3 V excitation must be amplified by a low-noise, low-offset-drift instrumentation amp such as the INA128 before ADC sampling. Designers must add their own temperature compensation scheme; for production medical devices a fully compensated MPX series part is often preferred.

Water Level / Tank Sensing
The MPX10GP serves water-level sensing applications where the hydrostatic head pressure stays below 10 kPa, for example shallow tanks, reservoirs, or other low-head measurement points. The male tube pressure port can be plumbed to a sensing line at the appropriate depth, while the vented gauge reference corrects automatically for atmospheric pressure variations. Because the device is uncompensated, the designer must correct for the temperature coefficient of water and the silicon bridge in the conditioning firmware.

Barometric Reference Design
For barometric pressure reference designs, the MPX10GP offers a low-cost transducer with a vented gauge reference that reads atmospheric pressure at the sensor inlet. The 0 to 10 kPa range comfortably brackets sea-level standard atmosphere (101.325 kPa is above this part, so for true barometry the higher-range MPX4115 family is more appropriate; the MPX10GP is suitable for differential or low-absolute-altitude reference work). The uncompensated bridge design lets the engineer build a custom trimming network for laboratory-grade accuracy.

Industrial Process Control
In industrial process control, the MPX10GP can monitor low-pressure gas or pneumatic lines where the working pressure is below 10 kPa, such as cleanroom pressure monitoring, vacuum system roughing gauges, or low-differential flow measurement. The 4-SIP module with male tube port integrates easily into industrial pneumatic manifolds. Engineers must add their own filtering against electrical noise and apply temperature compensation in software to meet industrial accuracy requirements.

Consumer Appliance Pressure Switch
The MPX10GP works well in consumer appliance pressure-switch designs such as dishwasher water-level detection, coffee machine flow monitoring, and small appliance pneumatic interlocks where pressures stay below 10 kPa. The uncompensated 35 mV full-scale output at 3 V excitation lets the designer build a low-cost comparator-based threshold detector with a single op-amp. Cost-sensitive consumer applications benefit from the MPX10GP's low unit price compared to compensated alternatives.

ڈیزائن نوٹس
The MPX10GP output sits in the 0 to 35 mV range at 3 V excitation, which is well within the noise floor of typical digital ground planes. Use a low-noise, low-offset-drift instrumentation amplifier such as the INA128 with a gain of about 50 to 100 to bring the signal into the 1.75 to 3.5 V range for an ADC. Keep the analog signal traces short and shielded from any digital switching or relay lines to prevent common-mode pickup.
Estimated: because the MPX10GP is uncompensated, typical silicon bridge sensitivity may shift on the order of -0.2% per degree Celsius and zero offset may drift similarly. For a 0 to 10 kPa design requiring better than 2% total error over 0 C to 70 C, plan to characterize the part in your fixture and apply multi-point temperature correction in firmware. Use a thermally stable voltage reference such as the REF5025 to drive the bridge excitation.
Do not apply liquids to the MPX10GP without checking media compatibility; the silicon diaphragm and gel coating are specified for clean, non-corrosive gases. For water or other liquid media, add a compatible isolation diaphragm and coupling fluid. Do not exceed the maximum pressure rating of 75 kPa (per the MPX family general spec) or the diaphragm may rupture; always confirm absolute pressure rating in the latest manufacturer datasheet before final design.
