Signal Wiring to Detectors
This wiring is for transmitting signals of cell electromotive force, thermocouple output
and cold junction compensation from a detector to the averaging converter. Use 6-core
shielded PVC insulated PVC sheathed control cables. The conductor two-way resistance
should be 10
Ω
or less. Keep the cables away from the power wiring. If a cable gland is
not installed on the wiring hole of the averaging converter, use a wire with an outside
diameter of 17 mm or smaller. If installed, use a wire with an outside diameter of 6 to
12 mm. The shields should be connected to cable shield ground terminals on the case of
the averaging converter.
