Temperature Control

The Elstein TRD 1 electronic temperature controllers analyse the signal of the thermocouple being integrated in each thermocouple heater.

The TRD 1 temperature controllers operate as quasi-continuous controllers and their factory settings are specially matched to the controlled process performance of Elstein infrared systems, so that practically no temperature fluctuations occur.

The two 0/12 V DC logical outputs control the Elstein thyristor switching units TSE. In addition, two programmable floating relay contacts are available. They can be used, for example, as alarm contacts in conjunction with the limit comparators.
