Hi
I have been asked to build a panel for pre-testing heater-bands on different extrusion heads, unfortunately within the factory we use both J Type and K Type thermocouple.
With 8 heaters to control and 8 Eurotherm 2204E controllers to control them I was hoping to avoid having to change the Type in each controller each time a head is changed, is it possible to add anything inline with one of the thermocouples so that the controller sees the same output from each thermocouple type?
My initial thoughts are a voltage divider of some type, possibly using a potentiometer brought inline with a toggle switch for each circuit.
The purpose of the test bench panel is only to preheat the units to an approximate temperature so an error of +/- 5 degrees would not be considered an issue.
Many thanks in advance
