– These special terminal blocks are used to
extend thermocouple compensating lines
in corresponding measuring circuits
– The compensating lines are made of
materials which, up to temperatures of
200 °C, have the same thermal
characteristics as the corresponding
thermocouples
– This ensures that no false thermoelectric
voltages result at the junctions of the
thermocouple/terminal
block/compensating line and that the
basic values according to
EN60584/DINEN60584 are adhered to
