Structure principle of diaphragm pressure gauge

When measuring the pressure of medium P acting on the diaphragm, the diaphragm is deformed, sealing liquid compression pressure meter measuring system, the formation of P- Delta P

Structure principle of diaphragm pressure gauge

Pressure. When the diaphragm rigidity is small enough, then P is also very small, close to the measurement of the medium pressure forming pressure gauge pressure system pressure.

1. Temperature characteristics:

The system consists of filling sealing liquid as pressure transfer medium diaphragm pressure gauge, is due to the temperature expansion coefficient of sealing liquid, the pressure gauge and value also increased with the compression part temperature, the temperature effect of volume expansion coefficient and sealing liquid, diaphragm stiffness and compression temperature, especially for the low range pressure meter the effect is more obvious. The general temperature error of the general pressure section is not more than 0.1%/ C. Therefore, the total temperature influence of the diaphragm pressure instrument is generally the sum of both the temperature influence of the general instrument and the temperature of the diaphragm pressure unit.
