Product Overview

MPX5999D is a highly integrated, high-range piezoresistive silicon pressure sensor that integrates signal conditioning, temperature compensation, and calibration in a single chip. It provides a stable analog output without the need for additional peripheral circuits. Supporting absolute pressure measurement of 0~1000 kPa (0~150 psi), the output voltage is proportional to pressure, ranging from 0.2~4.7 V (5V supply), which is compatible with the A/D input interface of microcontrollers/microprocessors. Adopting patented silicon shear stress strain gauge technology and a rugged epoxy unibody package (Case 867), it features a fluorosilicone gel inside to protect the chip. Operating temperature ranges from -40℃ to 125℃ with temperature compensation covering 0~85℃, making it an industrial-grade high-reliability pressure sensor widely suitable for automotive, industrial control, medical and other scenarios requiring strict pressure measurement.

Key Features

• Full Temperature Range Compensation：Built-in temperature compensation circuit ensures stable output within the operating range of 0~85℃, effectively offsetting the impact of temperature drift and guaranteeing measurement accuracy across the entire temperature range.
• Wide Pressure Range & High Sensitivity：0~1000 kPa wide pressure range with a sensitivity of 4.5 mV/kPa. The output signal is linearly related to pressure, and the analog output directly adapts to A/D conversion without complex algorithms.
• High Integration & Calibrated：Single-chip integration of sensing element, gain amplification, offset adjustment, temperature compensation, and factory calibration. Ready to use out of the box, greatly simplifying system design.
• Fast Response Characteristic：Response time is only 1 ms (10%~90% output change), enabling rapid capture of dynamic pressure changes, suitable for real-time monitoring scenarios.
• Rugged & Durable Design：Epoxy unibody package + fluorosilicone gel protection for strong resistance to harsh environments. The metal cover protects the sensing element, making it suitable for industrial media and automotive operating conditions.

Typical Applications

• Industrial Control & Automation：As an industrial-grade high-range pressure sensor, MPX5999D can be used for pressure monitoring of hydraulic and pneumatic systems. It is compatible with the A/D interface of PLCs or microcontrollers, providing real-time feedback on system pressure status to ensure stable equipment operation. The wide temperature characteristic adapts to complex industrial on-site environments.
• Automotive Electronics Systems：Suitable for pressure monitoring of automotive braking systems, fuel systems, and transmission hydraulics. The rugged package can withstand vibrations and temperature changes in automotive operating conditions. The 0~1000 kPa range covers various pressure monitoring needs of automobiles, and the analog output directly connects to the A/D channel of the on-board ECU.
• Hydraulic & Pneumatic Equipment：Adapts to pressure detection of air compressors, hydraulic pump stations, and pneumatic actuators. The high sensitivity (4.5 mV/kPa) can accurately capture subtle pressure changes, and the fast response characteristic ensures timely feedback when system pressure is abnormal, avoiding equipment overload.
• Medical Equipment：Used for airway pressure monitoring of medical devices such as ventilators and anesthesia machines. High precision and stability guarantee the accuracy of medical parameters. The wide operating temperature range adapts to temperature fluctuations in medical environments, and the epoxy package meets the reliability requirements of medical equipment.
• Test & Measurement Instruments：Serves as the core sensing element of pressure calibrators and portable pressure gauges. Factory pre-calibration and high-precision characteristics (±2.5% V FSS) ensure the credibility of measurement data. The analog output is easy to connect with the signal acquisition module of test instruments.
