TDX 9110N
TDX6 Temperature Scanner/Pyrometer
Installation and Operation Instructions
The TDX6 is an advanced design 6-point temperature
scanner and pyrometer. It continually scans six
grounded
tt
or ungrounded thermocouples, displays
the temperature of the thermocouple selected and has
adjustable trip points for each input. A trip point read/
scan knob provides for display and check/adjustment of
the thermocouple temperature trip point. If any trip point
is reached, its output turns ON and can be used as a
control signal or to initiate alarms and/or shutdown.

Using grounded thermocouples introduces the risk of odd currents or voltages being imposed on the thermocouple signal which can affect the accuracy of the reading. This is
an inherent problem of grounded thermocouples, and the reason why we prefer unground ed thermocouples.
