When mounting two or more sensor heads of the same model in parallel
•
The sensor may not output the correct voltage due to mutual interference. Make
sure that the distance between sensor heads adjacent to each other is larger
than the values shown in the table below. (This allows the display resolution
specification to be satisfied when the number of measurements to average is
"64".)
•
When two sensor heads are mounted in parallel, mutual interference can be
prevented by alternately oscillating the sensor heads using the synchronous
input terminal (
➮ page 4).
Tightening torque
To tighten the EX-305V set screw, apply a torque of 0.2 N•m or less.
To tighten the nut of the other sensor heads, apply a torque shown in the table
below or less.
•
If the applied tightening torque exceeds the specified one, the sensor
head may be deformed or malfunction.
•
If the sensor cable is installed in the same conduit as high voltage lines or
power lines, the sensor may malfunction. Be sure to keep the wiring
separate.
Note: Do not change the sensor cable length (3 m). If the cable is extended or cut,
the characteristics will change.
