Displacement sensors (proximity probes) channel 13-16
Displacement sensor mounting
If high absolute accuracy is required on the displacement
measurements, e.g. for position measurements channel 13-
16 can be applied for proximity probes.
This type of sensor needs -24 VDC sensor
power. This requires that a -24 V power supply is connected
between 0 and SP in the power plug used for supply current
to VCM-3.
Refer to the section “Power Connection – External Sensor
Power
” in the “Other Connections” section of this manual.
The sensor power terminal “SP” is internally connected to the
individual “SP” terminals for each sensor.
NOTE!
The color coding of the wires follows the
colors of the IN08x displacement sensor
series from Brüel & Kjær Vibro.
Maximum current output in this
configuration 45 mA/Channel.
