*device-x*' , outputting an average of all input thermocouples AND making available each thermocouple value.

I cannot find an off-the-shelf device to do this.

I am considering making a mockup for this using GASP! BRX - this AD platform has 16-bit analog out with 0-20mA.

BX-DM1E-M

BX-4THM4DA-1

BX-08THM

BX-08CD-3R

I may make the data available on an EA9 - simulating a heat-map.

After getting the temperature values (I assume into the R datatype) I would get MinMaxAve values then find the thermocouple that HAS the Min/Max values.

Being Real, I may have issues with the EQUAL contact. I will look at this if we decide to carry on.

The next step is to scale the AVERAGE temperature to a voltage/current signal that I send to a SOLO 9696. The SOLO will see this as its PV --- and control the chamber to THIS AVERAGE.

Any ideas/red flags?

[Edit] Change SV to PV - thanks Tinker
