Two-sensor Operation

Two-sensor operation enables mutual operation using the measured val-
ues from the two Sensor Heads to generate final outputs. Two kinds of out-
puts, A−B or A+B, can then be selected.
When two-sensor operation is selected, any scaling that is set for
each Sensor Head will be reset to the defaults. When scaling is
required during two-sensor operation, perform scaling after

When setting the Amplifier Units, set the 1CH Amplifier Unit to
RUN, then perform the settings for the 2CH Amplifier Unit.
POINT
Note: The ranges of display values and linear output values are automatically
doubled when two-sensor operation is used. An example application of
Sensor Heads is given in the following table when the sensing distance is
±
100 40 mm.
Linear output
Note: Correct distance operation cannot be performed if Sensor Heads with dif-
ferent sensing distances are used.
4 to 20 mA
A − B −80 to 80
A + B 120 to 280
