Specialized category for industrial pressure sensors used in manufacturing production equipment and control systems to convert gas, liquid, and steam pressure into electrical signals. Handles essential electronic components for pressure measurement and control in manufacturing sites including hydraulic machinery pressure monitoring, pneumatic system control, process equipment pressure management, and NC machine tool hydraulic control. Covers comprehensive industrial-grade pressure sensors designed for harsh manufacturing environments including gauge pressure, absolute pressure, and differential pressure sensors, high-precision digital output types, analog output (4-20mA, 0-10V) types, explosion-proof specifications, and high-temperature resistant models. Clearly distinguished from temperature sensors and flow sensors, classified specifically as electronic components dedicated to pressure measurement.
