Product Details

Battery supply LCD pressure gauge with Digital display

1.Description

QWB108 Digital lcd pressure gauge is electronic-structure and battery-powered, which make it very easy for on-site installation. Specifically, a high-precision piezo-resistive pressure sensor is used and the output signal is processed by the high-precision, low temperature drifting amplifier, then sent into the high-precision A/D converter to be converted into digital signal, after being computed and processed, the actual pressure value is showed on the LCD screen.

It has some benefits: flexible use, simple operation,safe and reliable etc. It is being widely used to measure and display the pressure of the fluid medium in hydro-power, water, petroleum, chemical, mechanical, hydraulic etc industries.

2.Features

Large-screen LCD display, back light,high resolution,easy to read

Automatically record the maximum pressure value during the measurement

Pressure on the percentage of dynamic display(the progress bar display)

Five engineering units: psi, bar, kpa, Mpa, kg / cm2

01 ~ 15minutes auto-shut off feature. 00 ~ 15minutes back light funciton

Micro-power consumption, over 2years in power-saving mode, 2,000 hours continuous operation.

Parameter correction, correct zero and error in field application.

Pressure range already set before use

Sampling rate: 4 times/sec

Applicable to gases and liquids compatible with stainless steel

4.Installation

QWB108 can be directly mounted in the hydraulic pipe by the mounting thread(for example G1/2”).In critical applications (such as severe vibration or shock), soft hose

is strongly recommended to connect the digital pressure gauge to reduce the effect caused

by the sever vibrations and shocks.
