Install the pipe by following the
arrow indication that shows the
air flow direction on the product.
Use straight piping 8cm or longer to
connect the Piping Port (Inlet side).
If straight piping is not installed, the
accuracy may vary by ± 2% F.S..
※ Straight Piping: The pipe is without
bending and the cross sectional areas of
the pipe keeps the same.
While installing the
KFP01A-101/201 to the pipe,
please apply air tube with I.D. 5 mm.
While installing the
KFP01A-005/010/050/100/500 to
the pipe, please apply air tube with
I.D. 4 mm.
※ The accuracy can vary by approximately
±2% F.S. when such tubing is not used.
Blow the air to flush out the foreign
matters, dust and etc. before installing
the pipe.
Uncleaned air may cause malfunction or
damage to the product.
Piping for the One-Touch Fitting, insert
the tube firmly into the fitting and make
sure it cannot be pulled out.
Also using the proper tube cutter is
recommended to ensure square edge

【NOTE:】
*1. In case hysteresis is set at less than or equal to 2 digits, switch output may chatter if input detected fluctuates near the set point.
*2. When using window comparator mode, the difference between two set points must be greater than the fixed hysteresis, otherwise
will cause the switch output to malfunction.
