Classification of pressure instruments by conversion principle
2011-6-30 17:05:59

Pressure instruments are roughly divided into four categories:

⑴Liquid column pressure gauge is based on the principle of hydrostatics, which converts the pressure into liquid column height for measurement.

⑵Elastic pressure gauge , it is measured by converting the measured pressure into the deformation displacement of the elastic element.

Electric pressure gauge , it is a measuring instrument that converts the measured pressure into electricity through mechanical and electrical components.

⑷Piston type pressure gauge , it is based on the principle of liquid transfer pressure of hydraulic press to convert the measured pressure into the mass of the weight added to the piston for measurement.
