QDB108 digital pressure gauge

Overview

The digital pressure gauge is a fully electronic structure, battery-powered, and easy to install on site. The front end adopts a high-precision piezoresistive pressure sensor. The output signal is amplified and processed by a high-precision, low-temperature drift amplifier, sent to a high-precision A/D converter, and converted into a digital signal that can be processed by a microprocessor. The LCD display shows the actual pressure value.

The intelligent digital pressure gauge is flexible to use, simple to operate, easy to debug, safe and reliable. It is widely used in hydropower, tap water, petroleum, chemical, machinery, hydraulic and other industries to measure and display the pressure of fluid media .

Features

◆Large-screen LCD display, high resolution , ignoring the value error;

◆Peak hold function, record the maximum pressure value during the measurement;

◆Dynamic display of pressure percentage, (progress bar display);

◆Five engineering unit options: psi , bar , kpa , kg/c ㎡  Mpa ;

◆Choose 1~15min automatic shutdown function;

◆Micro power consumption, working in power saving mode for more than 2 years, continuous working for 2000 hours;

◆Parameter correction function , the zero point and error value of the instrument can be corrected on site ;

◆The upper and lower ranges are limited;

◆Sampling rate: 4 times / sec;

◆Suitable for pressure measurement of various gases and liquids compatible with stainless steel.

◆High protection level, suitable for harsh working conditions such as outdoor.
