The digital pressure gauge is an on-line measuring instrument controlled by a single chip microcomputer. It adopts battery long-term power supply mode, no external power supply, and is easy to install and use. The digital pressure gauge can be used for the detection of gauge pressure, absolute pressure and vacuum (negative pressure). Its variety and installation form are various, and it can meet the needs of various measurement, especially in places such as erosion and vibration, and its extraordinary function.
Digital pressure gauges are widely used in hydropower, tap water, petroleum, chemical, mechanical, hydraulic and other industries to conduct on-site measurement display and control of fluid medium pressure.
Principle and structure of digital pressure gauge
The digital pressure gauge is transformed by the elastic deformation of the sensitive components (Bourdon tube, bellows, bellows) in the watch, and then the pressure deformation is transmitted to the pointer by the conversion mechanism of the movement inside the digital pressure gauge, causing the pointer to rotate to display the pressure. .
Digital pressure gauge structure: Its core component is a micromechanical silicon pressure sensor without any moving parts.
Advantages of digital pressure gauges
1. Digital pressure gauge is a portable instrument for AC and DC.
2. The high-performance microprocessor continuously corrects the performance and technical indexes of the digital pressure gauge to ensure the meter's long-term and 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 works for a long time.
4. Autoranging: Provides high resolution and precision in low pressure ranges 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. Zero return function: provide fast one-key zero return
7. Constant current charging: Overcharge, undervoltage automatic shutdown and automatic protection function with battery voltage ensure that the battery is not damaged by overcharge or undervoltage, and the battery has a long service life.
8. Micro-power under-voltage automatic protection function: Ensure that the digital display pressure gauge will not damage the battery due to under-voltage even if the operator continuously boots for too long.
9. The digital pressure gauge has rich functions and a multi-purpose meter.
10. The software is rich in content, simple and clear.
11. The digital pressure gauge adopts the thin-film panel tact switch, which has novel style and long button life.
12. The full scale can be adjusted directly on the panel.
13.Automatic shutdown: automatically shut down after 40 minutes to save battery
Micro camera is the product of modern high-tech, also known as micro monitor, which has the characteristics of small size, powerful function and good concealment.
Micro cameras are widely used, suitable for aviation, commerce, media, enterprises and institutions, families and other industries. The emergence of miniature cameras brings convenience to people's lives, and at t,he same time, some phenomena related to corporate secrets and personal privacy also arise.
