Introduction
DPG108 is a battery powered digital
pressure gauge, making for easy
on-site installation. The DPG108
uses a high-precision piezo-resistive
pressure sensor. 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 LCD display.
This flexible, simple to operate
digital pressure gauge is safe,
reliable, and easy to maintain.
The DPG108 is widely used in
hydropower, water, petroleum,
chemical, mechanical, hydraulic, and
other industries.
