Outside-mounted gauge, Inside-mounted gauge
Thread Content
Recently, I examined samples of Chuanyi pressure gauges, which included both external-card type and internal-card type pressure gauges. I would like to know what the difference between these two is and which one is used more often?
Those use not many balls,,, just like when you try to understand something with a stick – it doesn’t work :P Those that use more balls are the external threads M20×1.5, M14×1.5 :lol .
M20×1.5 and M14×1.5 are types of process connections; are bayonet and sleeve types also considered process connections?
External and internal clamps refer to the bayonet connection type of the pressure gauge casing
When it is necessary to install (fix) the pressure gauge on the dashboard: installing it from the outside (front side) of the dashboard inward (with the fixing elements inside the dashboard) is the external clamping type； The type installed from the inside of the dial towards the outside (with the fixing elements on the outside of the dial) is the internal clip type.
Does it mean with edges at the front and edges at the back? The front edge has mounting holes that are at the same level as the front dial, making it suitable for disc mounting ； The rear variant has mounting holes that are flush with the back, making it suitable for mounting.
Thank you for the introduction. Are there any pictures to help with understanding?
It’s the question of whether the installation edge is on the front or the back
There are slight differences at the slots between the case and the cover; it has no impact on those who use the watch
