MPXV5004GVP - 0/3.92kPa Vented Gauge Pressure Sensor | NXP
MPN: MPXV5004GVP ⚠ Lần mua cuốiMPXV5004GVP Tóm tắt
A pressure sensor transducer converts an applied physical pressure into a measurable electronic signal. The MPXV5004GVP is a vented gauge sensor, meaning it measures pressure relative to ambient atmospheric pressure through a vented reference side, making it ideal for applications where the surrounding barometric pressure is the natural zero reference. As a category, it sits within the hierarchy: pressure sensor -> sensor -> transducer -> electronic component, and is widely deployed in medical, HVAC, and consumer flow/level measurement.
Key features include on-chip temperature compensation and calibration over 0°C to 85°C, ratiometric analog voltage output, monolithic silicon construction using advanced micromachining and thin-film metallization, and a robust 8-SMD module with vertical port for easy tube/fitting attachment. The device integrates a sensitive implanted strain gauge with bipolar signal-conditioning circuitry on a single die. The combination of high accuracy (±1.25% typical), integrated calibration, and analog output simplifies host firmware by removing the need for complex digital compensation.
Typical applications include spirometry and respiratory airflow measurement, HVAC variable-air-volume (VAV) controllers, washing machine water-level sensing, altimeters and barometers, and patient monitoring airflow/pressure measurement. The wide supply tolerance (4.75 V to 5.25 V) and low current draw allow battery or line-powered deployments.
When designing with the MPXV5004GVP, ensure the vented reference port is exposed to ambient atmosphere (not sealed) for correct gauge operation, decouple VCC with a 100 nF + 1 µF capacitor pair within 5 mm of the supply pins, and account for the sensor's warm-up time before taking precision readings.

Ứng dụng tiêu biểu
MPXV5004GVP phù hợp cho 6 Áp dụngs: Spirometry / Respiratory Airflow Sensing, HVAC Variable Air Volume (VAV) Control, Washing Machine Water-Level Sensing, Barometric / Altimeter Measurement, Patient Monitoring Pressure Measurement, Industrial Vacuum / Low-Pressure Process Control.
Spirometry / Respiratory Airflow Sensing
The MPXV5004GVP's 0 to 3.92 kPa range is precisely matched to the differential pressure drop across a pneumotach flow head used in spirometers, CPAP monitors, and ventilator flow paths. Its vented gauge reference tracks ambient barometric pressure, eliminating drift during altitude or weather changes. The 1 V/kPa nominal sensitivity gives ~1 mV resolution per Pa at a 10-bit ADC with 5 V reference, sufficient for tidal-flow waveform reconstruction. Place the sensor across the flow-restriction element with short, equal-length pneumatic taps to minimize common-mode error, and decouple VCC with a 100 nF + 1 µF pair. Unlike bare strain-gauge sensors, the integrated temperature compensation across 0°C to 85°C removes the discrete compensation op-amps the design would otherwise require.

HVAC Variable Air Volume (VAV) Control
Building-automation VAV boxes measure duct differential pressure to compute airflow and modulate dampers. The MPXV5004GVP's 3.92 kPa full scale covers the 0 to ~0.5 PSI pressure range across an orifice plate in small-to-medium ducts, and its ratiometric analog output interfaces directly to a 5 V microcontroller ADC without an instrumentation front end. The integrated temperature compensation holds accuracy across the 0°C to 85°C commercial building envelope. Mount the sensor with both pneumatic taps to the duct and ensure the vented port remains exposed to ambient atmosphere. Versus a discrete transducer + op-amp chain, the MPXV5004GVP cuts BOM cost and PCB area while keeping long-term drift within calibration.

Washing Machine Water-Level Sensing
Appliance water-level sensors infer tub fill volume from the hydrostatic head of trapped air. The MPXV5004GVP's 0 to 3.92 kPa range maps directly to typical wash-tub fill heights (0-40 cm of water), and the 1 V/kPa sensitivity yields ~25 mV per cm of water at 5 V, simplifying firmware conversion. Its monolithic silicon diaphragm tolerates humid environments and the small reference vent equalizes barometric pressure so the reading tracks true water level rather than weather. Use a hydrophobic filter on the vented port to keep humidity out of the reference cavity. Compared with mechanical float switches, the MPXV5004GVP gives multi-level resolution for fabric-care algorithms and quieter, more reliable sensing with no moving parts.

Barometric / Altimeter Measurement
Although the MPXV5004GVP's 3.92 kPa range is narrow, it is well-suited to barometric weather-station and indoor altimeter applications measuring small barometric pressure variations around ambient. The vented gauge design references atmospheric pressure directly, so the output sits at the ratiometric mid-range and small pressure changes (e.g. 10 hPa weather events or 8 m altitude deltas) are easily resolved by a 12- or 16-bit ADC. Combined accuracy over temperature is dominated by the integrated ±1.25% VCC calibration. For higher-pressure barometric work, choose the MPXV5004GC7U or MP3V5004GP with identical specifications, and place the sensor away from air-handling turbulence for clean readings.

Patient Monitoring Pressure Measurement
Patient monitors use low-pressure sensors for airflow, CPAP circuit pressure, and non-invasive blood-pressure-cuff pressure measurement. The MPXV5004GVP's 0 to 3.92 kPa range, vented gauge reference, and integrated calibration match the pressures in CPAP circuit (typically <30 cmH2O) and cuff-deflation measurement. The ratiometric analog output feeds a 5 V ADC with predictable gain across supply variation, simplifying medical-device IEC 60601-1-2 EMI testing. Decouple VCC near the IC, route the analog output away from switching nodes, and add a small RC filter at the ADC input. This sensor should not be the sole measurement chain in life-support devices; use it as part of a redundant, validated measurement pathway.

Industrial Vacuum / Low-Pressure Process Control
Low-vacuum industrial processes (pick-and-place vacuum verification, packaging enclosure leak-test fixtures, pneumatic gripper pressure verification) often operate below 3.92 kPa and benefit from a calibrated analog sensor with integrated temperature compensation. The MPXV5004GVP's vertical male 3.3 mm tube port accepts standard pneumatic fittings, simplifying assembly. The 1 V/kPa sensitivity and ratiometric 5 V output support direct 10-bit ADC digitization with 5 mV resolution per Pa. Use short, equal pneumatic lines to minimize time delay, and place the vented port outside the process cavity to track atmospheric drift. Compared with bare silicon gauges, the MPXV5004GVP eliminates the calibration burden and provides a calibrated analog signal in a single SMD package.

Ghi chú thiết kế
Decouple VCC (pin 1) with a 100 nF ceramic capacitor plus a 1 µF bulk capacitor placed within 5 mm of the supply pin. The MPXV5004GVP integrates analog signal conditioning, so clean 5 V supply is critical to the ratiometric output accuracy. Use a linear LDO rather than a switching converter to drive the sensor if your board already has switching rails, or place a π-filter (10 µH + 10 µF + 10 µF) between the switching node and the sensor. Keep digital ground return currents away from the analog ground pin to avoid offset shift.
Route the analog output away from switching nodes (DC-DC, MCU clock traces, PWM fan lines) and place a small RC filter (10 kΩ + 100 nF) at the ADC input to band-limit noise. The vented gauge reference port must be exposed to ambient atmosphere and not sealed - if the design is enclosed, run a vent tube from the sensor reference port to outside the enclosure. Keep pneumatic tubing short and symmetric between the two pressure taps to minimize common-mode error in differential applications.
The MPXV5004GVP output is ratiometric with VCC, so for absolute accuracy use the same 5 V rail to drive both the sensor and the ADC's reference (or use an external precision reference and scale in firmware). Add a 1 ms to 10 ms warm-up delay before taking precision readings - the on-chip heater and die self-warming during the first few milliseconds after power-up can shift the output by a few mV. For highest accuracy, average 16+ ADC samples to suppress broadband noise on the analog output.
Do not occlude the vented gauge reference opening - sealing it converts the gauge sensor into a sealed-gauge or absolute reference and corrupts the reading. Do not exceed the maximum overpressure (consult datasheet for the verified figure; do not use this sensor in liquid media unless a protective fitting and filter are added, as direct water contact damages the silicon diaphragm. Do not apply reverse voltage to VCC; always confirm polarity before power-up. Do not rely on this single sensor for life-support patient monitoring without redundant sensing.
