Air leakage detection system used for
water-proof testing
Generally, air leakage tests are performed to evaluate water
resistance. Testing begins by placing a measuring tool into
the capsule. Next, air with equivalent pressure is supplied
to the capsule and the master, then the valves are closed. If
none of the air in the capsule seeps into the measuring tool,
the capsule’s air pressure will remain equal to that in the
master, and the differential pressure gauge will continue to
point to the center. However, if some air does seep into the
measuring tool, it will create an air pressure difference in the
amount indicated by the differential pressure gauge. Thus,
detection of air pressure differences is used as a criterion for
judging leakage. Every single unit of the ABS Coolant Proof
calipers and Coolant Proof micrometer is tested this way for
air leakage to help ensure product quality.
IP66 protection level
Level 6: Dust-tight
No ingress of dust.
Level 6: Protected against powerful water jet.
Water projected in powerful jets* against the
enclosure from any direction shall have no
harmful effects.
*Size of direct jets: uses 12.5 mm (inner diameter)
nozzle emitting a 100 kPa jet of water at 100 liters
per minute for at least 3 minutes from a distance of
approx. 3 meters.
IP67 protection level
Level 6: Dust-tight
No ingress of dust.
Level 7: Protected against the effects of temporary
immersion in water.
Ingress of water in quantities causing harmful
effects shall not be possible when the enclosure
is temporarily immersed 1 meter in water under
standardized conditions of pressure and time (30
min.).
