This article takes the standpoint of device ease of system integration and outputs usable directly for ADC sampling or downstream amplifiers, focusing on small-size SOP packaging with integrated multi-stage compensation pressure sensors. It emphasizes how packaging affects PCB layout and reliability, how compensation maintains stability across the full temperature range, and how production-to-shipment testing controls accuracy and consistency — enabling engineers and technical decision-makers to make informed selections early in design.

Environmental pressure sensors, with integrated metal construction and wide-range capability, provide stable, corrosion-resistant, and highly compatible pressure measurement solutions for industrial automation. This article explains how these sensors maintain high reliability and accuracy under harsh conditions from five perspectives: materials and structure, range adaptability, interface options, thermal stability, and engineering deployment. It aims to help decision-makers reduce integration costs and improve system stability.

Media-isolated pressure sensors use a metal diaphragm and oil-filled cavity to separate the silicon strain gauge from the measured fluid. By combining proper materials, diaphragm geometry, signal conditioning (amplified ratiometric or digital I2C/SPI outputs), and temperature compensation, these sensors achieve long-term, linear, and repeatable pressure output in water-meter hydraulic environments.
