Since there is neither a model nor an order number on the pressure gauge, it is still difficult for those who do not understand the pressure gauge to correctly describe a pressure gauge.
It is very important to correctly describe a pressure gauge, generally the following parameters should be provided:
1) Dial diameter: 40mm, 50mm, 63mm, 100mm, 160mm, etc.
2) Shell material: plastic, steel, stainless steel, copper
3) Interface material: copper, stainless steel (part with threaded end)
4) Measuring range: standard quantities are -1 to 0, 0.6, 1.5, 3, 5, 9, 15, etc.,
0 to 0.4, 0.6, 1, 1.6, 2.5, 4, 6, 10, 16, 25, 40, 100, 160, 250, 400, 600, 1000, 1600, etc. (commonly used unit bar)
5) Unit of measurement: Bar, Mpa, Kpa, Psi, etc. are commonly used, and two units may also be marked at the same time.
6) Radial installation: the installation thread is at the bottom of the pressure gauge; or axial installation: the installation thread is at the back of the pressure gauge
7) Interface thread: G1/8, G1/4, G1/2, G1, etc., M metric thread, NPT taper thread, etc.
8) Fluid-filled and shock-resistant: some watches are filled with liquid to resist vibration; some do not need to be filled with liquid
Possibilities: electrical contacts, output alarm points, 821.12 or 831.12, with chemical seals, etc.
Usually the dial of the WIKA pressure gauge will have the following information:
a) EN837-1: This is just a standard, not a pressure gauge model
b) KL 1 or 1.6: represents the accuracy level
c) BAR, Mpa: pressure unit
It is not possible to order a correct gauge with this information alone.
