7.1.3 MSI-TH-x

The MSI-TH-x allows thermocouple temperature measurement with
DS-MINITAUR). The common thermocouples types K, J and T are supported. For high temperature application also
type C is supported. A high precision cold junction compensation is included in the adapter.
The non-linearity of the thermocouple is compensated for in software. A TEDS chip (transducer electronic data-sheet)
provides automatic adapter identification by software and the calibration data.
In operation with the isolated
the differential SIRIUS® modules (or DEWE-43/DS-MINITAUR) only isolated thermocouples should be used, because
the thermocouple input is single ended.
