>> Pressure gauge with elastic sensing elements
- Pressure gauge is a device used to measure atmospheric pressure, when high high atmospheric pressure increases water and vice versa. It can measure the pressure exerted by the atmosphere using water, gas or mercury. The trend of pressure change can be forecasted in the short term weather forecast. Many measurements of barometric pressure are used in surface weather analysis to find grooves, high pressure zones, etc.

Pressure gauge with elastic sensing elements (including: manometer,  vacuum gauge) has a measuring range from -0.1 MPa to 250 MPa, with accuracy from 1% to 6%.

>> Other information
As a rule, the Pressure gauge is on the list of equipment required to be inspected by the General Department of Standards, Metrology and Quality of Vietnam and is under the state management authority of the Ministry of Science and Technology.

♦ Why requires equipment inspection?
• To ensure the stable operation of the equipment,
• Timely detect failures to prevent problems that can occur during work,
• Comply with and comply with legal regulations.

♦ Inspection conditions
The inspection environment must ensure:
• Temperature: (20 ± 5) °C;
• Relative humidity not more than 80%;
• Air-ventilated, dust-free and not heated from one side, avoiding shock and impact, if any, needle vibrations should not exceed 1/10 of the distance between the two smallest divisions.

♦ Inspection Preparation
• Pressure gauges to be inspected and standard ones must be left in the inspection room for at least 6 hours for them to reach the prescribed ambient temperature.
• Level balance (if present) and check the liquid level in the pressure system or standard Pressure gauge, then expel any air bubbles from the pressure system.
• Clean the connection of the Pressure gauge to be tested.
• Install the Pressure gauge to be tested in the working position according to the specified direction (write on the manometer to be verified). The allowable deviation from the specified direction is 5 '.
• For the Pressure gauge to be inspected, there is no symbol for the direction of installation that will be mounted vertically.

♦ Process of inspecting Pressure gauge
When performing the inspection of the Pressure gauge, the verification organization must proceed according to DLVN: 08-2011 including the following steps:
 > Step 1: External inspection:
 > Step 2: Technical inspection:
 > Step 3: Measurement testing:

♦ Term of inspection
The verification cycle of the Pressure gauge is 12 months.
