MPX5700DP differential pressure sensor 0 to 700kPa range 2.5% accuracy 4.7V output temp compensated analog out reliable for industrial

Features

• Differential Pressure Sensing – Measures pressure difference between two ports (P1 vs. P2), suitable for flow or filter monitoring.

• 0 to 700 kPa Full Scale – Wide range covering 0–101.5 psi or 0–7 bar, suitable for moderate to high pressure systems.

• ±2.5% Maximum Error (0–85°C) – High accuracy over temperature for critical measurements.

• 4.7V Analog Output at Rated Pressure – Ratiometric output (0.2V to 4.7V @ 5V supply) simplifies ADC interfacing.

• Temperature Compensated & Calibrated – On-chip compensation from 0°C to 85°C eliminates external circuitry.

• 5.0V Single Supply Operation – Easy integration with 5V microcontrollers and logic systems.

• Durable Dual-Port Package – Port positions at 0.112" diameter allow direct tubing connection for gases and dry air.

Applications

• Medical Equipment – Respiratory monitors, ventilators, CPAP machines, and patient monitoring systems.

• Industrial Process Control – Differential pressure across filters (clogging detection), air flow monitoring in ducts.

• HVAC Systems – VAV (Variable Air Volume) controllers, building pressure monitors, and filter status indicators.

• Automotive Diagnostics – Manifold absolute pressure (MAP) replacement, EV battery pack pressure monitoring, or cabin air filter sensing.

• Leak Detection Systems – Closed tank or pipeline leak verification by measuring pressure decay over time.

• Pneumatic Automation – Pressure feedback in robotic grippers, pick-and-place machines, and air cylinder controls.

• Scientific Instrumentation – Barometric pressure chambers, wind tunnel probes, and environmental test chambers.

Description

The MPX5700DP is a piezoresistive silicon differential pressure sensor integrating on-chip signal conditioning, temperature compensation, and calibration. Housed in a dual-port "PK" package, it provides a high-level analog output directly proportional to the applied differential pressure. With a full-scale pressure range of 0 to 700 kPa (0 to 101.5 psi), the MPX5700DP delivers a 4.7V output at rated pressure when powered by a 5.0V supply. Its monolithic design ensures excellent accuracy, low noise, and resistance to harsh environments, making it ideal for industrial, medical, and automotive applications requiring precise pressure measurement.
