ABSTRACT:
A pressure gauge comprising a thread tube, a printed circuit board carrying a pressure sensing device installed on one side of the printed circuit board and tightly packed with silicon rubber to form the end cover of the thread tube. When used for testing the pressure of acidic or alkaline liquid the pressure sensing device of the pressure gauge will not be brought into contact with the liquid, but can sense the pressure through the silicon rubber packing to test the pressure of the acidic or alkaline liquid, and the range of application of the pressure gauge covers the test of pressure of gas, acidic liquid, alkaline liquid and low pressure gas.
