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