Fill the pressure gauge with liquid, the main purpose is to reduce the impact of the environment on the measurement results. The specific performance is:
1. Shock resistance-stable pointer
When environmental vibration causes the instrument pointer to tremble or the relative pressure of the measured medium changes greatly, the filled fluid provides cushioning for the pressure gauge pointer. It can not only facilitate reading but also maintain the sensitivity of the pointer.
2. Protect internal components
The presence of liquid can provide lubrication, reduce friction and wear of internal components of the pressure gauge, extend its service life.
3. Help cooling and heat dissipation
The temperature of some measured media will affect the measurement; Frictional heating of pressure gauge components may also affect measurements. Oil filling can absorb a certain amount of heat and dissipate it, stabilize the operating temperature of the pressure gauge. Effectively avoid measurement errors caused by temperature changes.
