MPX2100DP - 100kPa Differential Pressure Sensor, 40mV | NXP
MPN: MPX2100DP ✓ Hoạt độngMPX2100DP Tóm tắt
A piezoresistive pressure sensor is a transducer that converts applied pressure into a change in electrical resistance via strain gauges diffused into a silicon diaphragm. As pressure deforms the diaphragm, the embedded Wheatstone bridge produces a differential voltage proportional to the pressure differential between the two ports. The MPX2100DP sits within the broader sensor hierarchy: pressure sensor -> MEMS transducer -> board-mount sensor -> electronic component. The 4-SIP package with axial tubes makes it suitable for through-hole mounting on PCBs and inline pneumatic systems, distinguishing it from surface-mount MEMS alternatives.
Key features include a 0-100 kPa measurement range, 40 mV full-scale span, 1.0% typical linearity, and on-chip temperature compensation over 0-85°C. The differential dual-port configuration allows measurement across a filter, orifice, or any element where two pressure taps are available. According to the manufacturer datasheet, the device provides a calibrated output with minimal offset drift and is laser-trimmed for span accuracy, simplifying interface to ADC front ends and instrumentation amplifiers.
Typical applications include medical instrumentation (respiratory monitors, blood pressure measurement, inhalers), industrial process control (HVAC pressure monitoring, filter clog detection, vacuum systems), and consumer devices (altimeters, barometers, appliance pressure sensing). The wide operating pressure range and differential measurement capability make it especially suitable for low-pressure pneumatic and biomedical applications where bidirectional or differential readings are required.
When designing with the MPX2100DP, select a low-noise, low-drift instrumentation amplifier (such as an INA12x series or similar) for the mV-level output, and ensure stable 10 V excitation for rated performance. Decouple the sensor supply near the device pins with a 0.1 uF ceramic capacitor to suppress supply noise. The tube ports should use flexible silicone tubing with appropriate clamps to avoid mechanical stress on the package.

Ứng dụng tiêu biểu
MPX2100DP phù hợp cho 6 Áp dụngs: Medical Respiratory Monitor, HVAC Filter Clog Detection, Industrial Vacuum System Monitor, Blood Pressure Measurement, Appliance Pressure Sensing, Process Control Pressure Transmitter.
Medical Respiratory Monitor
The MPX2100DP is well-suited for medical respiratory monitoring where differential pressure across a flow-restriction element must be measured accurately. The 0-100 kPa range covers typical breathing-circuit pressures, and the dual-port differential configuration is ideal for inline flow-sensing using a Fleisch pneumotachograph or similar restriction. The 40 mV full-scale span with on-chip temperature compensation from 0C to 85C provides reliable measurements across clinical environments, and the 1% typical linearity is sufficient for breath-rate and tidal-volume calculations when paired with a low-noise instrumentation amplifier such as the INA128.

HVAC Filter Clog Detection
The MPX2100DP excels in HVAC filter-clog detection systems where differential pressure across an air filter indicates when maintenance is required. The dual-port configuration connects directly to the upstream and downstream sides of the filter, producing a mV output proportional to pressure drop. As the filter loads, the differential rises and the sensor output increases proportionally. With a 0-100 kPa range and 40 mV span, the device covers typical residential and light-commercial duct pressures, and the through-hole 4-SIP package mounts securely inside HVAC control enclosures for long-term reliability.

Industrial Vacuum System Monitor
For industrial vacuum-system monitoring, the MPX2100DP provides accurate differential pressure readings between the vacuum pump inlet and the process chamber, helping detect pump degradation, leaks, and process anomalies. The 0-100 kPa differential range comfortably covers typical vacuum levels down to -100 kPa gauge, and the 4-SIP tube-port design accepts standard silicone tubing for direct plumbing into vacuum lines. The on-chip temperature compensation ensures stable readings despite pump-generated heat, while the ratiometric mV output simplifies signal conditioning with a single-supply instrumentation amplifier.

Blood Pressure Measurement
In non-invasive blood pressure measurement (NIBP) systems, the MPX2100DP serves as the differential pressure transducer across an inflatable cuff, providing the raw pressure waveform from which systolic and diastolic values are derived. The 0-100 kPa range covers cuff pressures up to 300 mmHg with margin, and the dual-port differential design rejects common-mode atmospheric variations. The 40 mV full-scale output, while small, is well-matched to medical-grade 24-bit ADCs and instrumentation amplifiers like the AD620 or INA128, which provide the gain and noise rejection required for accurate oscillometric measurements.

Appliance Pressure Sensing
Consumer appliances such as washing machines, dishwashers, and coffee makers use the MPX2100DP for water-level and pump-pressure monitoring. The differential dual-port configuration measures pressure across a flow restriction or pump outlet, while the through-hole 4-SIP package withstands typical appliance manufacturing processes including wave soldering. The 1% linearity and 40 mV span are sufficient for end-of-cycle detection and fault diagnostics, and the 10 V supply is readily derived from a small AC-DC module. Cost-sensitive appliance designs benefit from the MPX2100DP's mature supply chain and NXP's long-term product support.

Process Control Pressure Transmitter
In industrial 4-20 mA pressure transmitters, the MPX2100DP provides the primary differential pressure measurement that drives the current loop. The 0-100 kPa range covers common process pressures in water treatment, chemical dosing, and pneumatic systems. The dual-port configuration supports bidirectional or gauge-referenced measurements, and the on-chip temperature compensation reduces the calibration burden in field-deployed instruments. When paired with a precision 16-bit ADC and a 4-20 mA loop transmitter such as XTR105, the MPX2100DP forms the heart of a reliable, low-cost pressure transmitter for SCADA and DCS systems.

Ghi chú thiết kế
The MPX2100DP requires a stable 10 V DC excitation source for rated 40 mV full-scale output. Estimated: at 10 V supply, typical bridge current is approximately 6 mA. Use a precision reference such as REF02 or REF5050 with a low-dropout regulator to derive the 10 V rail, and decouple with a 0.1 uF ceramic capacitor placed within 5 mm of the sensor supply pin to suppress supply noise that would otherwise appear on the mV signal.
The 40 mV full-scale output is small and easily corrupted by noise. Route the sensor outputs as a differential pair with matched trace lengths and a guard ground plane. Use a low-noise instrumentation amplifier such as INA128 or AD620 with gain of 50-100 to bring the signal into the 2-4 V ADC input range. Avoid ground loops by using a single-point star ground at the ADC reference.
Common design mistakes with the MPX2100DP include: (1) using an unregulated 10 V supply that drifts with load, causing span error proportional to supply variation; (2) omitting temperature compensation calibration, which can introduce 1-2% FS error across the 0-85C range; (3) applying excessive mechanical stress to the tube ports, which can crack the silicone die attachment and cause offset drift; (4) ignoring moisture ingress through the tube ports, which requires hydrophobic filters for humid-media applications.
The MPX2100DP is compensated over 0C to 85C, but its long-term thermal cycling characteristics depend on the host assembly. Avoid mounting the sensor near heat sources such as power resistors or microcontrollers. Estimated: thermal hysteresis is typically 0.5% FS over 0-85C when the device is mounted on a standard FR4 PCB with normal copper pours. For higher-precision applications, mount the sensor on an isothermal section of the board or use thermal isolation.
