Ken (Customer) asked a question.
Thermocouple and heater power in one connector?
Are there connectors available that will handle both TC and Heater power? Frequently you have to have both, and it would be nice to have them go thru one cable and be replaced as a set. Are such things available (for reference, most of the heaters I deal with are 120-240, less than 10A)
You can get thermocouple pins for circular mil-spec type connectors. You will likely have to build your own connector. Be aware that going down this path may introduce noise into the measurement.
Wouldn't electrical field coupling interference of the power being drawn by the heaters induce extra electricity into the thermocouple and throw off your reading?
