Product Overview

MPX5500DP is a high-sensitivity, dual-port piezoresistive monolithic integrated pressure sensor designed specifically for the A/D input interface of microcontrollers/microprocessors. It supports pressure measurement of 0~500 kPa (0~72.5 psi). The chip integrates signal conditioning, full-temperature range temperature compensation, and factory calibration functions. The output voltage is linearly proportional to pressure, ranging from 0.2~4.7 V (5V supply) with a high sensitivity of 9.0 mV/kPa. Adopting a Case 867C dual-port epoxy unibody package with built-in fluorosilicone gel to protect the sensing element, it operates at a temperature range of -40℃~125℃ with temperature compensation covering 0~85℃. As an industrial-grade high-reliability analog output pressure sensor, it is suitable for pneumatic, hydraulic, automotive electronics and other scenarios requiring dual-port differential measurement.

Key Features

Typical Applications

• Industrial Pneumatics & Pneumatic Control：As a dual-port pressure sensor, MPX5500DP is suitable for inlet/outlet pressure monitoring of pneumatic systems. The dual-port design facilitates differential pressure measurement. 9.0 mV/kPa high sensitivity can accurately control the pressure of pneumatic actuators, and the wide temperature characteristic tolerates temperature fluctuations in industrial sites.
• Automotive Electronics Systems：Suitable for automotive intake systems, brake boosters, and transmission hydraulic monitoring. The dual ports can collect high and low pressure signals respectively. The fast response (1ms) ensures real-time feedback of vehicle conditions, and the rugged package tolerates automotive vibration and high-low temperature operating conditions.
• Medical Equipment：Used for airway differential pressure monitoring of ventilators and anesthesia machines. The dual ports are suitable for intake and exhaust pressure collection. ±2.5% high precision ensures the accuracy of medical parameters, and fluorosilicone gel protection meets the cleanliness requirements of medical equipment.
• Test & Measurement Instruments：Serves as the core component of portable pressure gauges and differential pressure calibrators. High sensitivity and linear output ensure measurement accuracy. The dual-port design supports switching between differential/gauge modes, adapting to multi-scenario testing needs.
• Hydraulic System Monitoring：Adapts to pressure detection of small and medium-sized hydraulic pump stations and hydraulic actuators. The dual ports can monitor the pressure difference between the inlet and outlet of the oil circuit. The fast response characteristic timely captures pressure peaks, avoiding equipment overload damage.
