Analyze the principle, structure and advantages of digital pressure gauge
Digital pressure gauge is an online measuring instrument controlled by single chip microcomputer. It adopts long-term battery power supply mode, without external power supply, easy to install and use. Digital pressure gauge can be used for gauge pressure, absolute pressure, vacuum (negative pressure) detection, its variety and installation forms are diverse, can meet various measurement needs, especially in erosion, vibration and other places, it shows its extraordinary performance.
Digital display pressure gauges are widely used in hydropower, tap water, petroleum, chemical, machinery, hydraulic and other industries to perform on-site measurement, display and control of the pressure of fluid media.
Principle and structure of digital pressure gauge
The digital display pressure gauge uses the elastic deformation of the sensitive elements (Bourdon tube, bellows, bellows) in the table, and then the pressure transformation of the movement in the digital display pressure gauge transmits the pressure deformation to the pointer, causing the pointer to rotate to display the pressure .
Digital display pressure gauge structure: its core component is micro-mechanical technology silicon pressure sensor, without any moving parts.
Advantages of digital pressure gauge
1. The digital pressure gauge is a portable instrument for AC and DC.
2. The high-performance microprocessor continuously revises the various performance and technical indicators of the digital pressure gauge to ensure that the instrument can be used for a long time and in a wide temperature range without affecting the accuracy of the digital pressure gauge.
3. Low power consumption: The battery adopts imported nickel-hydrogen high-energy battery to ensure that the digital pressure gauge can work for a long time.
4. Auto range: Provide high resolution and accuracy in low pressure range when needed
5. Stable mode: The stable function is used to stabilize the reading. It will show the average of the first four readings
6. Return to zero function: Provide quick one-key return to zero
7. Constant current charging: with over-charging of battery voltage, automatic shutdown of under-voltage and automatic protection, to ensure that the battery is not damaged due to over-charging or under-voltage, and the battery has a long service life.
8. Micro power consumption under-voltage automatic protection function: to ensure that the digital display pressure gauge will not damage the battery due to under-voltage even if the operator continuously turns on for too long for some reason.
9. The range function of digital display pressure gauge is rich, and one table is multi-purpose.
10. The software is rich in content and easy to operate.
11. Digital display pressure gauge adopts membrane panel light touch switch, with novel style and long key life.
12. The full scale can be adjusted directly on the panel.
13. Auto power off: Auto power off after 40 minutes to save battery
