Oil filled pressure gauge is suitable for ships and other industrial equipment to measure the pressure of the medium with strong corrosion, high temperature, high viscosity, easy crystallization, easy solidification, and solid floating matter. Especially suitable for occasions with strong vibration in the working environment.
The measuring system of oil filled pressure gauge consists of a joint and a spring tube. Due to the change of the measured pressure, the free end of the spring tube is displaced. The connecting rod drives the pointer at the end of the sector transmission gear to rotate, and the corresponding pressure value is indicated on the dial. In order to eliminate the gap movement between the rotating shaft gears of the sector gears, a disc-shaped hairspring is installed on the rotating shaft gears.
