1.Description
QZP-108 Intelligent Digital 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, easy debugging, safe, reliable etc. So they have been widely used in hydro-power, water, petroleum, chemical, mechanical, hydraulic and other industries to measure and display the pressure of the fluid medium.
2.Features
Large-screen LCD display, back light,high resolution,easy to read
Automatically record the maximum pressure values during the measurement
Pressure on the percentage of dynamic display, (the progress bar display)
Five engineering units: psi, bar, kpa, Mpa, kg / cm2
0 ~ 15min auto-off feature.
Micro-power consumption, work over 2 years in power-saving mode, 2,000 hours continuous work.
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
QZP-108 can be directly mounted in the hydraulic pipe on the road through the mounting thread
(BSP1/4"). 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.
6.Operation Instructions
Open or close the gauge:short time press "ON / OFF" button,
Shift engineering unit: long time press "ON / OFF" button,
Clean the peak pressure value: short time press "ZERO" button
Clean the showing pressure value: long time press "ZERO" button (Note:only available when without any pressure )
Packaging & Shipping
Standard exporting package: each unit has individual box and packed in paper box. Waterproof protect.
