The MS case protects internal components from:
- Physical damage
- Industrial environmental conditions
- Mechanical vibrations
This robust design helps extend the service life of the instrument in demanding environments.
6. Brass Internal Components for Reliable Performance
The internal mechanism of the pressure gauge is made from brass components, ensuring reliable operation when measuring non-corrosive fluids and gases.
Brass internals offer several advantages:
- Good corrosion resistance for general industrial media
- Reliable mechanical performance
- Long service life
- Cost-effective pressure measurement solution
Brass components are commonly used in commercial and industrial pressure gauges due to their durability and reliability.
7. 2% Full Scale Deflection (FSD) Accuracy
The Japsin Instrumentation commercial pressure gauge offers 2% FSD accuracy, which ensures dependable readings for industrial monitoring applications.
Accuracy is essential for:
- Maintaining consistent process control
- Preventing over-pressure situations
- Ensuring reliable equipment performance
With this level of accuracy, the gauge is suitable for general industrial applications where precision pressure monitoring is required.
Working Principle of Pressure Gauges
Most commercial pressure gauges operate based on the Bourdon tube principle.
A Bourdon tube is a curved metal tube that tends to straighten when pressure is applied inside it. The movement of the tube is mechanically linked to a pointer that moves across the dial scale.
The process works as follows:
- Pressure enters the gauge through the threaded connection.
- The pressure acts inside the Bourdon tube.
- The tube expands or straightens slightly due to internal pressure.
- This movement is transferred to a mechanical linkage.
- The linkage moves the pointer on the dial.
- The pointer indicates the pressure reading on the scale.
This simple mechanical design provides accurate and reliable pressure measurement without requiring external power.
