Short answer: Into which major categories are pressure measuring instruments classified based on their conversion principle? What is its measurement principle? Pressure measuring instruments can be roughly divided into four categories: (1) Manometric pressure gauges, which utilize the principles of hydrostatics to convert the measured pressure into a height of a liquid column for measurement. ⑵ An elastic pressure gauge converts the pressure to be measured into a deformation displacement of an elastic element for measurement. ⑶ An electrical pressure gauge is a measuring instrument that converts the pressure to be measured into an electrical signal using mechanical and electrical components. ⑷ A piston pressure gauge operates on the principle of fluid pressure in hydraulic presses; it converts the pressure to be measured into the mass of the weight applied to the piston for measurement purposes.

Correct. Pressure measuring instruments can be roughly divided into four categories: (1) Manometric pressure gauges, which utilize the principles of hydrostatics to convert the applied pressure into a height of a liquid column for measurement. ⑵ An elastic pressure gauge converts the pressure to be measured into a deformation displacement of an elastic element for measurement. ⑶ An electrical pressure gauge is a measuring instrument that converts the pressure to be measured into an electrical signal using mechanical and electrical components. ⑷ A piston pressure gauge operates on the principle of fluid pressure in hydraulic presses; it converts the pressure to be measured into the mass of the weight applied to the piston for measurement purposes.
