Integrated digital pressure gauge with display and control used to monitor hydraulic fluids. It monitors the pressure via the resistance measured on an isolation membrane. The output signal is amplified by a high-precision, low temperature drift amplifier. The signal is then fed into a high accuracy A/D converter for the microprocessor to process and then show on the LED display.
This flexible, simple to operate digital pressure gauge is safe, reliable, and easy to maintain. The DPG104 is widely used in hydro-power, water, petroleum, chemical, mechanical, hydraulic, and other industries.
