MPX2100GP Обзор
A pressure sensor transducer generates an electronic signal proportional to the applied pressure, typically by exploiting the piezoresistive effect in silicon. The MPX2100GP belongs to the board-mount pressure sensor family, a subset of signal-conditioning sensors that sit between the physical environment and the microcontroller analog front end. In the broader sensor taxonomy it falls under silicon MEMS -> piezoresistive sensor -> board mount pressure sensor -> signal chain component.
Key features include a maximum operating current of 6 mA, a Wheatstone bridge output topology, 58.02 psi (400 kPa) maximum overpressure rating, and an operating temperature range suited for industrial environments. The on-chip temperature compensation eliminates the need for external compensation networks, simplifying the analog front end. The 4-SIP module with port-style barbed tube integrates the sensing element and the compensation network into a single through-hole package that is easy to mount and seal with flexible tubing.
Technically, the device uses a diffused silicon strain gauge Wheatstone bridge laser-trimmed for span and offset, then temperature-compensated across 0 to 85°C. The differential output of 0 mV to 40 mV over 0 to 100 kPa gives ~0.4 mV/kPa sensitivity, which is normally amplified by an instrumentation amplifier such as the NXP MPX2010 family counterpart or a dedicated sensor AFE.
Typical applications include HVAC controllers, altimeters and barometric instruments, medical respiration monitors, industrial pneumatic gauges, and weather-station barometric pressure sensing. The 4-SIP barbed port supports flexible tubing routing for sealed pressure taps in pneumatic manifolds.
When designing with the MPX2100GP, allow adequate mechanical strain relief on the tube port and provide a stable low-noise 10 V excitation supply. The Wheatstone bridge output is ratiometric to supply voltage, so any supply noise or ripple couples directly into the output.

Типичное применение
MPX2100GP подходит для 6 применениеs: HVAC Air Pressure Monitoring, Barometric Altimeter and Weather Station, Medical Respiration and Sleep Apnea Monitoring, Industrial Pneumatic System Monitoring, Automotive MAP Sensor Upgrade, Drone and UAV Altitude Hold.
HVAC Air Pressure Monitoring
The MPX2100GP's 0-100 kPa range and 40 mV span make it well suited for HVAC duct and filter pressure drop monitoring in commercial building automation systems. Its 4-SIP barbed port accepts standard 3/16 in flexible tubing commonly used in pneumatic duct taps. The vented gauge reference compensates for altitude, allowing the same calibration across multi-story buildings. For differential filter-loading measurement, pair it with a second sensor and a low-offset instrumentation amplifier.

Barometric Altimeter and Weather Station
The MPX2100GP's full atmospheric 100 kPa range covers sea-level barometric pressure (~101 kPa) down to high-altitude weather-station pressures. Its 0.4 mV/kPa sensitivity gives adequate resolution for 0.1 hPa pressure change detection when amplified with a gain-100 instrumentation amp. The vented gauge port automatically references ambient pressure, so altitude-corrected barometric readings are computed from the absolute measured value. The through-hole SIP package with barbed port allows sealed weatherproof enclosure mounting.
Рекомендуется
Medical Respiration and Sleep Apnea Monitoring
The MPX2100GP is suitable for medical respiration flow monitoring in CPAP/BiPAP machines and sleep apnea diagnostic equipment. Its on-chip temperature compensation eliminates drift across body-temperature ambient conditions, and its 40 mV span delivers adequate signal-to-noise ratio when amplified by an instrumentation AFE. The barbed port integrates with standard medical-grade silicone tubing. For low-pressure airflow measurement below 10 kPa, the MPX2010GP is the more sensitive drop-in alternative.
Рекомендуется
Industrial Pneumatic System Monitoring
The MPX2100GP fits industrial pneumatic control panels monitoring 0-100 kPa regulated air pressure in factory automation and process control. Its 400 kPa overpressure margin absorbs water-hammer and regulator overshoot spikes. The 4-SIP unibody module with barbed port accepts standard pneumatic tubing for sealed manifold taps. For higher pressures above 100 kPa, the MPX2200 family extends to 200 kPa in the same MPX series with mechanical compatibility.
Рекомендуется
Automotive MAP Sensor Upgrade
The MPX2100GP's 100 kPa range covers naturally-aspirated gasoline engine manifold absolute pressure sensing. Aftermarket automotive engine management systems use it as a drop-in MAP sensor for fuel injection calibration, replacing dedicated NXP MPX4115A or MPX4101A in custom builds. The through-hole SIP package allows direct PCB mounting into engine bay ECUs. Verify temperature range and vibration tolerance against SAE J1455 automotive environmental specs before deployment.
Рекомендуется
Drone and UAV Altitude Hold
The MPX2100GP delivers barometric altitude hold data for hobby and commercial UAV flight controllers where its 100 kPa range and 40 mV span provide sufficient resolution after instrumentation amp conditioning. Its small 4-SIP form factor and low 6 mA consumption suit weight- and power-constrained UAV avionics bays. The vented gauge port must be weatherproofed to prevent humidity ingress that could corrupt the reference. For racing drones requiring higher update rates, the MPX2100 family is paired with a fast-response instrumentation amp.

Заметки по проектированию
Estimated: With a 40 mV full-scale span and a typical sensor signal, the bridge output is highly susceptible to coupled supply noise. Use a low-noise linear regulator (e.g., LT3042 or LP2985) to provide the 10 V excitation rather than a switching regulator; any ripple on VCC appears as common-mode noise that the instrumentation amplifier must reject. Add 100 nF ceramic bypass capacitors at pins 1 and 3, placed as close to the SIP pins as PCB layout permits.
Do not confuse the MPX2100GP pinout with the MPX2100DP. The GP variant is a 4-pin single-port gauge sensor with pins 1 (VCC), 2 (+Vout), 3 (GND), 4 (-Vout). The DP variant is a 6-pin dual-port differential sensor with an entirely different pin assignment. Cross-check the datasheet package drawing against the PCB silkscreen before reflow; swapping them will cause incorrect readings and potentially damage the bridge.
Route the bridge output traces as a tightly coupled differential pair from the SIP pins to the instrumentation amplifier input pins. Keep trace lengths matched to within 5 mm to preserve common-mode rejection. Use a ground pour on the top layer under the sensor with a single-point stitch to the analog ground at the instrumentation amp reference pin; do not split the ground plane under the bridge.
The barbed tube port must be mechanically strain-relieved to prevent tube-side forces from translating into the sensor body and corrupting the reading. Use a flexible silicone tubing section with a clamp or zip-tie strain relief within 25 mm of the port. For vibration-prone applications (automotive, industrial), pot the tube-port-to-barb junction with RTV silicone after assembly.
