ESMPGK intelligent digital pressure controller for -100KPA~0~100MPA

The ESMPGK intelligent digital display pressure controller adopts a standard industrial dial design with a large high-brightness digital display, providing clear and intuitive readings, suitable for long-distance observation. The product integrates a high-precision pressure sensor with a microprocessor chip, capable of real-time pressure data acquisition and display, and supports free setting of upper and lower control points. Automatic control and alarm functions are realized through relay output.

The instrument features intelligent settings such as pressure hysteresis and start-stop delay, effectively preventing frequent equipment start-stop, ensuring more stable and reliable operation. The housing is made of stainless steel with a high protection level, strong shock and interference resistance, suitable for various complex working conditions. It adopts standard threaded interfaces for easy installation and can directly replace traditional pointer-type electric contact pressure gauges.

It is widely used in constant pressure water supply, air compressors, hydraulic systems, HVAC systems, fire-fighting networks, and various automated equipment pressure monitoring and control scenarios, making it an ideal choice for achieving automated and intelligent pressure management.

    Working Principle

    The diffusion silicon pressure sensor senses changes in pressure and converts the physical quantity of pressure into a weak electrical signal. The signal processing circuit amplifies, filters, and converts this weak signal from analog to digital. Finally, the display shows the pressure value directly in digital form.
