Embodiment Construction
[0019] In order to further describe the present invention, specific examples of implementation are illustrated below in conjunction with the accompanying drawings.
[0020] First install the bellows 2-5 on the lower part of the concave opening 2-2 on the sensing diaphragm of the pressure gauge. The bellows 2-5 is filled with antifreeze, and the bellows 2-5 is installed with a pressure sensor with pressure transmission capability. The diaphragm 2-4 is provided with a process hole 2-3 on the side of the pressure gauge sensing diaphragm part 2-1. When the lower joint 1-5 of the pressure gauge indication part is screwed into the upper recessed opening 2-2 of the pressure gauge sensing diaphragm part, the pressure sensing diaphragm 2-4 is clamped between the lower joint 1-5 of the pressure gauge indication part and the pressure gauge Between the recessed opening 2-2 on the sensing diaphragm part. While screwing in part of the lower joint 1-5 of the indication part of the pressure ...
