Precautions
J
MOUNTING
The mounting screw for the pressure leading part is a PT1/4
taper screw. Do not use any other type of screw.
Apply sealing tape to the PT1/4 screw part so that there will be no
pressure leakage.
The most suitable wrench is 22 mm (0.866 in.) in size.
Make sure that the maximum tightening torque applied to mount
the E8AA is 36.14 ft S lbf (49 N S m).
Do not use the E8AA for applications in which the E8AA comes
into direct contact with medical or food products.
Diaphragms
If the diaphragms are damaged, the Unit will not operate properly.
Do not insert a screwdriver or steel wire into the interior of the
pressure-sensitive parts.
The characteristics of the Unit will change if foreign material is
stuck to the stainless steel diaphragm.
J
CORRECT USE
Hollow Pipe
The cable has a hollow pipe in order to keep the pressure inside
the Sensor the same as the atmospheric pressure. If the pipe is
clogged, the accuracy of the Sensor may be lowered.
Do not bend or impose a heavy weight on the output cable.
Make sure that the tip of the output cable is open and not clogged
with dust or water.
If it is necessary to cut the output cable, make sure that the tip of
the hollow pipe is not clogged.
