GAP MEASUREMENT
When checking the gap between the workpiece and the nozzle, as shown in the illustration, the output of the E8EB varies with the surface
roughness of the workpiece or the dimensions of the nozzle.

Gap (m)
The output varies with the surface
roughness of the workpiece even though
the gap is constant.
The rougher the surface of the work-
piece is, the more noticeable the varia-
tion of output is with a small gap. The
variation rate versus gap change is not
large in cases like these.
The larger the nozzle diameter is, the
larger the variation rate of output versus
gap change is.

Precautions
J
MOUNTING
The pressure port has an Rc (PT) 1/8 taper screw. Apply sealing
tape around the female taper screw so that no pressure leakage
will occur.
The most-suitable wrench is 17 mm in size.
Make sure that the tightening torque of the M5 female screw is
9.8 N S m or 100 kgf S cm (7.22 ft S lbf)
Diaphragm
If the diaphragm is damaged, the Pressure Sensor will not
operate properly. Do not insert a screwdriver or steel wire into the
interior of the pressure-sensitive parts through the pressure port.
J
CORRECT USE
Available Gases
No corrosive or flammable gas can be used.
Filter the gas with an appropriate air filter so that the applied gas
will be free of moisture or oil.
Pressure Setting
A rubber bushing is provided with the E8EB. After the pressure is
set with the pressure adjuster, cover the adjuster with the rubber
bushing so that no dust or any other foreign material will
penetrate into the interior of the E8EB.
