MPXV5004G7U - 3.92kPa Vented Gauge Pressure Sensor | NXP
MPN： MPXV5004G7U ✓ 啟用中MPXV5004G7U 概覽
What is a gauge pressure sensor? A gauge pressure sensor measures pressure relative to atmospheric pressure through a vented reference port, which is essential for applications where absolute atmospheric pressure would distort the reading. In the broader sensor hierarchy, gauge pressure sensors are a subset of piezoresistive transducers, which are a subset of pressure sensors, which fall under the sensor category in electronic measurement systems. The MPX series from NXP integrates the sensing element, signal conditioning, and calibration on a single silicon die.
Key features include on-chip signal conditioning, factory calibration, and temperature compensation from 0 C to 85 C. The device operates from a single 4.75 V to 5.25 V supply and provides a ratiometric analog output proportional to applied pressure. The integrated port design accepts a 0.034 inch (0.86 mm) female tube connection for direct airflow or liquid coupling.
The architecture uses a single-crystal silicon diaphragm with a diffused piezoresistive Wheatstone bridge. Laser-trimmed resistors and on-chip ASIC signal conditioning deliver a linear, amplified output that requires no external compensation components. The dual-vent port design provides stable operation in vented gauge applications where the reference side must be exposed to ambient pressure.
Typical applications include HVAC airflow monitoring, medical respiratory equipment, variable air volume (VAV) controllers, industrial process control, and consumer appliance pressure feedback. The 3.92 kPa full-scale range is specifically optimized for low-pressure pneumatic and respiratory sensing where higher ranges would sacrifice resolution.
When designing with this part, ensure the supply is regulated to within 5 percent and use ADC sampling at rates above 1 kHz to capture pressure transients. Decouple the supply pin with a 100 nF ceramic capacitor placed within 5 mm of the device. The sensor output is ratiometric to the supply - a 5.0 V supply produces a 1.0 V to 4.9 V output, while a 5.25 V supply scales proportionally.

典型應用
MPXV5004G7U 適用於 6 應用s: HVAC Airflow Monitoring, Medical Respiratory Equipment, Variable Air Volume (VAV) Box Control, Industrial Process Control, Consumer Appliance Pressure Feedback, Environmental Monitoring Stations.
HVAC Airflow Monitoring
The MPXV5004G7U's 0 to 3.92 kPa vented gauge range aligns precisely with the static pressure drop across HVAC duct flow elements, while the 1.0 V to 4.9 V ratiometric analog output interfaces directly to standard 0-5 V ADC inputs. This sensor is commonly mounted inline with a Venturi or orifice plate in variable air volume (VAV) boxes; unlike differential-only sensors it provides a single-ended output that requires no external instrumentation amplifier. Combined with on-chip temperature compensation from 0 C to 85 C, it eliminates the need for software linearization in commercial building controllers.
推薦
Medical Respiratory Equipment
The MPXV5004G7U's 3.92 kPa full scale matches the typical airway pressure range of CPAP machines, ventilators, and spirometers. Integrated factory calibration and temperature compensation simplify FDA 510(k) submission documentation. The sensor output drives the patient pressure feedback loop; unlike digital-output sensors it requires no I2C driver and integrates directly with legacy analog front ends in respiratory therapy devices. The vented gauge reference ensures accurate measurement regardless of barometric pressure changes.
推薦
Variable Air Volume (VAV) Box Control
In VAV box controllers the MPXV5004G7U measures duct static pressure to modulate damper position, maintaining zone airflow at the setpoint commanded by the building automation system. The 0 to 3.92 kPa range captures the typical 0 to 1.5 inch H2O duct pressure span. The 4.75 V to 5.25 V supply range matches 24 VAC wall adapters with 5 V regulators. The 8-DIP module mounts directly on a through-hole control board.
推薦
Industrial Process Control
The MPXV5004G7U serves in low-pressure industrial process loops such as cleanroom pressure differential monitoring and gas flow measurement. The 1.0 V to 4.9 V analog output drives 4-20 mA current loop converters through a resistor network, enabling integration with legacy PLC analog input modules. On-chip signal conditioning eliminates the need for external instrumentation amplifiers that are typically required for raw bridge outputs. Calibration is performed at the factory, removing per-unit trimming in production.
推薦
Consumer Appliance Pressure Feedback
In appliances such as vacuum cleaners, coffee machines, and washing machines, the MPXV5004G7U provides closed-loop pressure feedback for motor speed control and blockage detection. The 3.92 kPa full scale accommodates typical vacuum cleaner suction pressures of 2 to 3 kPa with headroom. The through-hole 8-DIP package survives vibration environments better than surface-mount alternatives. Unlike MEMS digital sensors, the analog output requires no microcontroller for I2C decoding, reducing BOM cost in cost-sensitive consumer designs.
推薦
Environmental Monitoring Stations
The MPXV5004G7U can detect room pressure differentials in biosafety laboratories, hospital isolation rooms, and cleanroom facilities. The vented gauge configuration provides accurate differential pressure regardless of altitude or weather-related barometric changes. The 0 to 85 C operating range covers indoor and outdoor enclosure environments. Analog output allows easy integration with battery-powered monitoring nodes via low-power ADCs, and the 1.0 V offset output clearly identifies zero-pressure state for diagnostic purposes.

設計說明
Decouple the VCC pin with a 100 nF ceramic capacitor placed within 5 mm of the device, in parallel with a 10 uF tantalum or aluminum polymer bulk capacitor for supply-noise immunity. The MPXV5004G7U output is ratiometric to the supply, so noise or ripple on the 5 V rail couples directly into the pressure reading. Use a low-noise LDO (e.g., LP2985 or TPS7A45) instead of a switching regulator for the analog supply rail to achieve best noise performance.
Route the VOUT trace away from switching converter inductors, digital clock lines, and PWM signals. Use a ground guard ring or grounded copper pour on either side of the analog output trace. The output bandwidth is limited by the sensor's internal compensation; an RC low-pass filter (1 kohm + 100 nF, fc approximately 1.6 kHz) can be added at the ADC input if system noise exceeds the signal of interest.
The MPXV5004G7U is calibrated for 0 C to 85 C operation. Outside this range the offset and span drift will degrade accuracy beyond the datasheet specifications. In outdoor enclosures, mount the sensor away from heat sources such as power MOSFETs, transformers, and direct sunlight. For below-freezing operation, add thermal insulation or active heating to maintain the calibrated temperature window.
Do not apply reverse pressure (vacuum) to the vented gauge port beyond the datasheet limit - it may permanently damage the diaphragm. The vent port (typically on the bottom of the package) must remain unobstructed and exposed to ambient atmospheric pressure. Covering the vent port alters the reference and causes incorrect readings. Do not use the sensor in condensing humid environments without additional moisture protection, as condensation inside the port cavity can cause drift.
