MPXV7007DP 概述
A piezoresistive pressure sensor is a MEMS device in which implanted resistors change resistance when deflected by applied pressure, producing a millivolt-level signal that is amplified and offset within the same silicon die. Compared to other transducer families, integrated pressure sensors such as the MPXV7007DP remove the need for external amplification, trimming, and thermal compensation networks, simplifying microcontroller- and microprocessor-based data acquisition.
Key specifications include a 5 V typical supply (4.75 V to 5.25 V), 7 kPa full-scale span in both positive and negative pressure directions, 5% accuracy over 0 °C to 85 °C, and 1 ms response time suitable for real-time flow and blockage detection. The dual-port top-side port geometry is convenient for hose or tube mounting.
The transducer employs bipolar signal conditioning combined with thin-film metallization and laser-trimmed calibration, allowing direct ADC input on most microcontrollers. The ratiometric output scales with supply voltage, preserving accuracy when powered from unregulated rails. Internal EMI/RFI filtering and reverse-supply protection improve robustness in industrial and appliance environments.
Typical applications include HVAC damper feedback, respiratory/CPAP airflow monitoring, liquid level detection in sealed containers, washing-machine water-level sensing, and industrial process control loops. Designers also use it in tire-pressure monitoring prototypes and altitude simulators for UAVs.
When integrating the MPXV7007DP, mount the part with port fittings oriented away from vibration sources and add a 0.1 µF decoupling capacitor adjacent to the supply pin. For differential measurements, route both ports through identical tubing to minimize common-mode error caused by wind or acceleration.

典型应用
MPXV7007DP 适用于 6 应用s: HVAC Damper Pressure Feedback, Respiratory and CPAP Airflow Monitoring, Washing Machine Water-Level Sensing, Sealed Container Liquid Level Detection, Industrial Process Control Loops, UAV Altitude Simulator and Indoor Flight Test.
HVAC Damper Pressure Feedback
The MPXV7007DP measures the small pressure differential across HVAC duct dampers and variable-air-volume boxes, giving closed-loop feedback to a microcontroller running the building automation system. With a ±7 kPa span and 0.5 V to 4.5 V ratiometric output, it interfaces directly with 5 V ADCs without amplification, and the dual horizontal ports accept inline tubing across the damper. The 1 ms response time is fast enough to track damper-induced transients, while internal temperature compensation maintains ±5% accuracy over the entire HVAC operating range. Designers typically low-pass filter the analog output to remove fan-induced turbulence noise above 100 Hz.
推荐
Respiratory and CPAP Airflow Monitoring
Used in CPAP machines and ventilator prototypes, the MPXV7007DP senses the small bidirectional pressure swing across a flow restrictor in the breathing circuit. Its ±7 kPa span captures typical mask pressures, while the 0.5 V to 4.5 V analog output drives 5 V medical front-end ADCs with no external gain stage, simplifying isolated analog front ends. The integrated MEMS diaphragm and gel isolation maintain drift-free operation over the long session lengths required for sleep therapy. Engineers convert the voltage reading to instantaneous flow via a software look-up table calibrated at production.
推荐
Washing Machine Water-Level Sensing
The MPXV7007DP serves as a sealed differential pressure sensor that translates water column height in the air-trap tube of a washing machine into an analog voltage, allowing main boards to detect empty, low, medium, and full load levels without mechanical pressure switches. Its 8-BSOP surface-mount package mounts vertically above the sump, while the dual port geometry accepts hose connections on the top side. Integrated signal conditioning eliminates the external op-amps used in legacy designs, reducing BOM cost and improving reliability under thermal cycling between wash and spin phases.
推荐
Sealed Container Liquid Level Detection
Industrial gas analyzers, chemical reservoirs, and beverage dispensing equipment use the MPXV7007DP to measure hydrostatic pressure differential across sealed tanks with independent inlet and outlet ports. The bidirectional ±7 kPa span detects both charging and discharging cycles, while the calibrated 5% accuracy ensures repeatable level readings across temperature shifts inside warm enclosures. Surface-mount 8-BSOP assembly on a small PCB pod minimizes intrusion into hermetic containers and supports automated pick-and-place production.
推荐
Industrial Process Control Loops
Factory automation controllers integrate the MPXV7007DP into 4-20 mA bridge circuits and PID loops monitoring differential pressure in filter-clog detection, vacuum pickup, and cleanroom pressure verification. Its 5 V ratiometric output maintains calibration across long cables and noisy 24 V industrial rails when paired with a local 5 V regulator, while its 1 ms response time tracks rapid process excursions. The 8-BSOP package withstands standard SMT profiles for control panel builders integrating PLC logic and analog front-end channels on the same board.
推荐
UAV Altitude Simulator and Indoor Flight Test
Drone and indoor flight-test benches use the MPXV7007DP to simulate barometric altitude changes by varying low-pressure air applied to its dual ports, exercising flight controllers with deterministic pressure ramps. The ±7 kPa bidirectional range reproduces 200 to 1000 m altitude profiles with the resolution needed for stable PID tuning, while the compact 8-BSOP package fits inside benchtop test rigs. Engineers drive the supply with a regulated 5 V rail and read the ratiometric output through the same debug ADC used during flight.

设计说明
Place a 0.1 µF ceramic decoupling capacitor within 5 mm of the supply pin (VCC) and route a short, low-impedance ground return directly to the GND pin to prevent switching noise from the host MCU coupling into the analog output. Keep digital signal traces away from the pressure ports and from the analog output trace. Mount the device with port fittings pointing horizontally (top-side orientation) so tubing does not carry mechanical stress into the gel-isolated diaphragm.
The analog output of the MPXV7007DP is ratiometric to the 5 V supply; any noise or drift on VCC will translate directly into the reading. Use a linear 5 V regulator rather than the MCU's switching rail, and add a 10 µF bulk capacitor at the supply pin to suppress transients. For long cable runs to industrial PLCs, buffer the output with a low-offset op-amp and consider shielded twisted pair to reject common-mode EMI.
Do not exceed the ±7 kPa differential rating, because overpressure beyond the gel-isolated diaphragm can permanently damage the sensor element. For sensing the difference between vacuum and ambient, ensure both ports see gas, not liquid, to avoid water-column bias on the diaphragm. Mount the sensor with the dual ports pointing horizontally to keep condensate out of the internal cavity and extend service life in washing-machine and CPAP environments.
