Weidmüller thermocouple elements are
specially designed to transmit very small
voltages in temperature measuring circuits.
Special busbars ensure that no false
signals are transmitted in the terminal
when temperature differences between
the positive and the negative paths exist.
This high measuring precision is required,
for example, in aircraft engine performance
test rigs, complicated chemical processes,
controllers, etc.
I. Configuration of a temperature
measuring circuit
1 Thermocouple (sensor) 4 Reference junction
2 Thermocouple terminals 5 Supply conductors (to and
from)
3 Compensating conductor 6 Measuring instrument
These thermocouple terminals shown in
this measuring circuit thermoelectrically
transmit thermoelectric voltage from the
thermocouple to the reference junction
and the indicator unit via the
compensating conductor. Thermocouple
terminals are required for constructing a
temperature circuit.
