Core Function Real-time continuous pressure monitoring of fluid and gas in industrial production pipelines and mechanical equipment. Provide pressure feedback signals for automatic control loops to adjust pumps, valves and compressors to maintain stable system pressure. Overpressure and underpressure safety protection: trigger alarm or cut off equipment operation to avoid pipeline burst and mechanical failure. Built-in self-diagnosis function detects circuit faults, signal drift and medium leakage, upload fault codes to industrial control systems. Support remote data collection, realize unattended monitoring and data recording for industrial IoT systems. 3. Working Principle Most industrial pressure sensors adopt piezoresistive sensing technology: Measured medium pressure acts on stainless steel isolation diaphragm and causes slight elastic deformation. Built-in strain resistors produce linear resistance changes corresponding to actual pressure value. Wheatstone bridge converts resistance fluctuation into weak analog voltage signals. Internal amplification, filtering, temperature compensation and conversion circuits output unified standard analog or digital signals for industrial control equipment. 4.
