PG-104 digital pressure gauge

1Overview

The digital pressure gauge is a fully electronic structure, powered by batteries, and easy to install on site. The front-end adopts high-precision piezoresistive pressure core, which is processed by amplifier and microprocessor, and the actual pressure value is displayed by LCD.

This intelligent digital thermometer is flexible to use, easy to operate, easy to debug, and safe and reliable. Widely used in industries such as hydropower, tap water, petroleum, chemical, mechanical, hydraulic, etc., to measure and display the pressure of fluid media

IIfeature

◆ Dual screen display, clear and easy to read display content

◆ 5-digit real-time pressure display on the main screen

◆ The secondary screen can display the maximum value, minimum value, peak value, and ambient temperature

◆ Graphic display of pressure percentage and battery level

◆ Overvoltage flashing prompt to prevent instrument overvoltage damage

◆ White backlight, easy to view at night

10 types of pressure unit conversions, universal

The collection rate can be selected from 30 seconds/time to 100 times/second, with a wider range of applications

The automatic shutdown function effectively extends battery life

• install

It can be directly installed on hydraulic pipelines or containers through pressure pipe fittings (M20 * 1.5) (other sizes of fittings can be specified when ordering).

VIFunction settings:

6.1Button Function

“”Function description of the power on/off key, also known as the "S1" key:

• Short press in measurement mode for on/off function
• Press and hold for 3 seconds in measurement mode to enter setting mode
• Short press to enable parameter modification in setting mode, the modified parameter will flash. Short press again to confirm the parameter modification, and the modified parameter will stop flashing.

“”Backlight on key, also known as the "S2" key, function description:

• Short press in measurement mode for backlight on/off function
• Long press and hold for 3 seconds in measurement mode for quick unit switching function
• In the setting mode, to set the parameter shift and subtract one function, continuously shift or subtract one for a long time

Function description of the "ZERO" reset key, also known as the "S3" key:

• Short press in measurement mode to clear peak values, maximum values, and minimum values. When the secondary screen displays the ambient temperature, this short press function is invalid.
• Press and hold for 3 seconds in measurement mode to reset the pressure zero point display function
• In the setting mode, add one function to the set parameters, continuously adding one for a long time

Note:For the convenience of describing the settings, all three buttons are named with their numbers "S1", "S2", and "S3". In both normal and advanced user settings modes, if there is no button operation within 30 seconds, the measurement mode will be returned from the settings mode.
