Weidmüller thermocouple terminals 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 negative paths exist. This high
measuring precision is required, for
example, in an aircraft engine performance
test rigs, complicated chemical processes,
controllers, etc.
Busbar material corresponds to thermal
and compensating conductors

measuring circuit
1 Thermocouple (sensor) 4 Reference junction
2 Thermocouple terminals 5 Supply conductors (to and from)
3 Compensating conductor 6 Measuring instrument
The 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.
