Mini pressure gauges refer to those pressure gauges with smaller diameter and dedicated design, they are micro and portable. It is easy to carry, it can be installed into the very limited space. Due to its dedicated design, the pressure elements becomes rotating deformation under the pressure of the medium, so as to drive the pointer on the scale to indicated different readings.
Pressure gauge, instrument for measuring the condition of a fluid (liquid or gas) that is specified by the force that the fluid would exert, when at rest, on a unit area, such as pounds per square inch or newtons per square centimetre.
It is important to select a pressure range that is approximately twice the normal operating pressure of the media. The maximum operating pressure should not exceed 75% of the full scale range. If a gauge is not selected considering these criteria, it may result in fatigue of the Bourdon tube.
