The explosion-proof smart pressure controller integrates pressure measurement, display, output, and control into one intelligent digital device. With a fully electronic structure, it features an oil-filled piezoresistive pressure sensor with an isolation diaphragm. High-precision A/D conversion and microprocessor processing allow real-time pressure display, providing one analog output, four switch outputs, and RS485 communication.
Easy to install, operate, and adjust, this controller is highly reliable and can replace most mechanical pressure switches. It is widely used in industries such as hydropower, water supply, oil, chemicals, machinery, and hydraulics for real-time pressure monitoring and control in hazardous environments.
