Air Purging
This product is equipped with an air purging mechanism. The air purging mechanism improves resis-
tance to the environment (over coolant or dust) of the linear scale by supplying clean compressed air
inside the scale main unit.
As shown in "4.5.3 Connection", supply compressed air through the specied air device by connecting
to either of the M5 screw holes provided at both sides of the scale main unit.
4.5.1 Air Flow Supplied to the Scale
Supply air ow at 10 L to 20 L/min per scale.
Air should slightly come out from the closed part of the dust-proof rubber lips.
Adjust the air ow referring to the descriptions below.
y When using Mitutoyo's xed diaphragm (ID: Ø0.9)
Make adjustment with the air pressure, so that the air ow becomes 10 L to 20 L/min (per scale unit).
(Ref.) When supplying air to a scale: Air ow approx. 12.7 L/min with 0.1 MPa of air pressure
Air ow of approx. 19 L/min with 0.2 MPa of air pressure
y When using other xed diaphragms
Make adjustment with the air pressure, so that the air ow becomes 10 L to 20 L/min (per scale unit).
For information on the air ow and pressure relationships, refer to the ow characteristics (ID of the
xed diaphragm and ow-pressure relations) provided by each pneumatic component manufacturer.
y When using ow rate adjustable valves
Make adjustments so that the air ow becomes 10 L to 20 L/min (per scale unit).
NOTICE
Make sure not to supply a large amount of air before making adjustments. Otherwise, it may cause components
to break thereby resulting in malfunctions.
4.5.2 Recommended Air Supply Devices
An air dryer is not required for this product.
Do not supply air to the air supply device directly from the compressor. Make sure to supply com-
pressed air through a main line air lter. The oil mist lter element should be replaced after a year.
Attach the xed diaphragm to the scale side.
The specications and the manufacturer models for recommended air devices are described in the
following.
If the specications are identical, it is ne to purchase and use a product manufactured by another
company.
