MPX2010GP - 10 kPa Vented Gauge Pressure Sensor | STMicroelectronics
MPN: MPX2010GP ✓ Hoạt độngMPX2010GP Tóm tắt
A pressure sensor is a transducer that converts an applied gas or fluid pressure into a proportional electrical signal. Pressure sensors fit into the sensor hierarchy as follows: pressure sensor -> force/pressure transducer -> MEMS sensor -> semiconductor device. Within this hierarchy, piezoresistive sensors use a strained silicon diaphragm whose resistance changes with mechanical deformation; signal-conditioning circuitry converts this Wheatstone-bridge change into a millivolt-level voltage output that downstream amplifiers can scale to 0-5 V or 4-20 mA.
The MPX2010GP uses a single monolithic silicon diaphragm with an integrated strain gauge and thin-film resistor network. On-chip temperature compensation holds sensitivity within tight limits across the operating range, removing the need for external thermistor networks. The device operates over a -40 C to +125 C range and is specified for 0 to 10 kPa differential or gauge pressure, making it suitable for low-pressure medical, HVAC, and instrumentation uses. The vented gauge port references the back side to ambient pressure, eliminating vacuum-pump calibration.
Typical applications include medical respiration monitors, HVAC variable-air-volume (VAV) controllers, industrial process instrumentation, altimeters, and low-pressure laboratory measurement. The 25 mV full-scale output requires a low-noise instrumentation amplifier (INA, AD620-class) to drive an ADC. The MPX2010GP series remains a workhorse for low-pressure designs and is widely second-sourced.
When designing with this device, route the high-impedance mV signal on a guarded, short trace and add RC low-pass filtering at the amplifier input to suppress RF rectification. Avoid mechanical stress on the plastic port during PCB assembly - the silicone gel isolation only protects the die from chemical and thermal attack, not from mounting force.

Ứng dụng tiêu biểu
MPX2010GP phù hợp cho 6 Áp dụngs: Medical Respiration / Airway Pressure Sensing, HVAC Variable-Air-Volume (VAV) Controllers, Industrial Process Low-Pressure Monitoring, Barometric Altimeter / Weather Station, Portable Handheld Pneumatic Tools, Laboratory Low-Pressure Measurement.
Medical Respiration / Airway Pressure Sensing
The MPX2010GP's 0-10 kPa vented-gauge range aligns directly with human airway and spirometer pressure envelopes (typical peak inspiratory pressure < 5 kPa). The on-chip temperature compensation holds span accuracy across body-temperature variation, simplifying calibration in CPAP, ventilator, and incentive-spirometer designs. The silicone-gel isolation accepts humidified breathing gas without sensor damage. Pair the 25 mV output with a low-noise INA333 or AD620 instrumentation amplifier to drive an isolated medical ADC; the result is a Class-IF-ready pressure channel for IEC 60601-compliant designs.

HVAC Variable-Air-Volume (VAV) Controllers
Building-automation VAV boxes operate in the 0-1.5 PSI duct-pressure band, an exact match for the MPX2010GP's 0-10 kPa (1.45 PSI) full-scale range. The vented-gauge port references ambient, eliminating vacuum-pump calibration on commissioning. The 1 ms response time tracks rapid damper-induced pressure transients without lag. Combined with a low-cost microcontroller ADC (through an INA), this sensor delivers accurate airflow estimation while the on-chip temp-comp ensures stable readings across 0-50 C rooftop HVAC environments.

Industrial Process Low-Pressure Monitoring
Cleanroom differential pressure, filter clogging detection, and laboratory vacuum/positive-pressure enclosures typically operate in the 0-10 kPa band. The MPX2010GP's linear mV output and ratiometric 10 V excitation integrate cleanly into 4-20 mA loop transmitters via an INA-x-V-to-I stage. The SIP package with 4.93 mm male port accepts standard pneumatic tubing for rapid panel-mount integration. The -40 to +125 C operating range covers outdoor and process-side environments.

Barometric Altimeter / Weather Station
Although absolute barometric pressure is typically 100 kPa, weather-balloon and indoor-altimeter designs often measure small differential pressure above local baseline. The MPX2010GP vented-gauge reference and 0-10 kPa span let designers subtract local barometric offset and resolve sub-100 m altitude resolution. The 1 ms response captures gust events, and the SIP port simplifies tubing to a reference chamber. Add a low-pass RC filter to suppress wind-induced acoustic noise.

Portable Handheld Pneumatic Tools
Battery-powered nailers, tire inflators, and pneumatic-tool regulators rely on low-cost pressure feedback in the 0-1.5 PSI range. The MPX2010GP's 6 mA supply current and 10 V excitation are compatible with a boost-converter-fed portable rail. The through-hole SIP package absorbs vibration better than SMT-only alternatives in shock-prone tools. The on-chip calibration eliminates per-unit trim, supporting high-volume consumer-tool manufacturing.

Laboratory Low-Pressure Measurement
Research instruments measuring gas chromatography column back-pressure, vacuum-chamber low-pressure monitoring, and microfluidic device pressure all sit comfortably within 0-10 kPa. The MPX2010GP's linear 25 mV span and calibrated offset simplify software calibration; the silicone-gel isolation accepts clean dry gases used in lab environments. The 4.93 mm tube port connects directly to standard 1/8 inch pneumatic fittings via inexpensive adapters, easing lab-bench integration.

Ghi chú thiết kế
The MPX2010GP outputs only 25 mV full-scale, so PCB layout is critical. Route the four bridge traces as a guarded differential pair with the guard driven by a unity-gain buffer of the common-mode voltage. Keep trace length under 25 mm, place the instrumentation amplifier within 30 mm of the sensor, and add a 1-10 kHz RC low-pass filter on each input to suppress RF rectification that can otherwise appear as a DC offset error.
Do not apply fluids directly to the silicone gel - the gel isolates the die from chemical attack but is not a sealed pressure port. Use dry gases only. Also avoid mechanical stress on the plastic port during PCB assembly; clamp the body, not the port. Excitation above 12 V DC can permanently damage the bridge.
Use a star-ground topology: ground the sensor excitation return at the same point as the instrumentation amplifier reference pin to eliminate ground-loop errors. Add 100 nF ceramic decoupling at the bridge Vs+ pin and 10 uF bulk capacitance. For 4-20 mA loop output designs, place a TVS diode at the loop input to meet IEC 61000-4-2 ESD immunity.
