For some use cases, customers are advised to use a pressure gauge with filled liquid. The oil-filled pressure gauge can prevent many conditions.
- Filling liquid can be divided into glycerin and silicone oil, the most widely used filling liquid is glycerin.
- The pointer is shaken sharply due to vibration or pulse. At this time, the filling liquid of the pressure gauge can suppress vibrate of the pointer and ensure the correct pressure value.
- Strong vibration or pulse on the instrument not only affects the interpretation of the pressure value, but also damages the internal components and reduces the life of the pressure gauge. The filling fluid can make the measuring instrument have cushioning and vibrate resistance function. At the same time, the interlocking components such as the internal Bourdon tube can also be lubricated by the filling liquid to reduce the damage of the components.
***Different filling liquids can be selected based on different working environments and temperatures.***
