Stainless Steel Wire Diameter
Vernier calliperMeasures the stainless steel wire diameter;
- measurement resolution of 0.01mm
- measurement accuracy of ±0.03mm
- measurement range of 150mm
MicrometerMeasures stainless steel wire diameters
preferable for diameters less than 1mm;
- typically has a 10 times better measurement resolution of 0.001mm
- measurement accuracy of ±0.004mm
- measurement range of 25mm
Stainless Steel Woven MeshTwo measurements are necessary to define the
mesh, all other parameters can be calculated
from these two;
- Mesh
- Wire Diameter
Ruler ‘0’ is lined
up along an
inside wire
There are 4 stainless steel wires per inch
The mesh is 4 mesh by 1.60mm wire diameter
The naked eye can count the wires per
inch of meshes up to about 10 but more
difficult for meshes above this
Stainless Steel Woven Mesh
Defined by following Parameters
Mesh – the number of openings per lineal inch
(2.54mm) refer to previous slide
Aperture – the distance between two adjacent
wires (opening)
Wire Diameter – the thickness of the wire before
weaving
Pitch – the centre to centre distance between two
adjacent wires (= aperture + wire diameter)
% Open Area – the ratio of the aperture area to the
total mesh area (calculated from the aperture and
the wire diameter)
Counting GlassGreatly magnifies the view and is used for fine mesh
½ inch- count wires x 2
¼ inch- count wires x 4
