1.      Description

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, with backlight, 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 function

◆ Micro-power consumption, battery powered.

◆ 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

It can be directly mounted in the hydraulic pipe on the road through the mounting thread

(1/4”NPT). 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.

5.User notes

1)        Stored and used in an environmental temperature of-10℃~60℃,the relative humidity less than 80%.

2)        Should be concentric and parallel when connect digital pressure gauge and pressure system.

3)        Please use 9V alkaline battery(6LR61) when replace the battery.

4)        When installing the gauge,please use right way

5)        For special medium (oxygen),no oil operation.
