The Johnson Controls K16RA-48H thermocouple helps maintain gas-fired equipment safety by confirming that a pilot flame is present before gas flow is allowed to continue. Installed with its sensing tip in the pilot flame, this heavy-duty coaxial component generates a small 20–30 mV electrical signal from the heat at its dissimilar-metal junction. That signal holds the compatible gas sa... https://partsfe.ca/k16ra-48h-johnson-controls-heavy-duty-thermocouple
