| 説明 | We'll start with this: I am thoroughly apologetic about the abundance of old photography going up lately. This is what happens when you take photos for 6 months, and process none of them. I'm finally going through them now, and posting them as I process them.We'll get to new, and better, stuff soon! I promise!About this photograph: This is the flame sensor from the furnace in my house. This is what is responsible for detecting when the gas has lit or, more importantly, when it has not. The model of furnace that we have has a known problem where, over time, the flame sensor no longer produces the needed current when the gas has ignited resulting in the furnace shutting off the gas because it believes that the gas did not light.A partial resolution involves replacing the original (single prong) flame sensor with the dual-prong flame sensor. We made this replacement about five years ago.What you see above is the flame sensor I took out of the furnace about about two weeks ago when it began exhibiting the symptoms again. This was the last thing I expected to find. There was significant build up of something on one of the sensor prongs. I have no idea what this is, or how it got there, but I am relatively sure that it wasn't there when I put the sensor in.Note that this is likely not organic (such as mould) since this sensor sits directly in the path of the flame when it is lit. I suspect this has to do with a temperature gradient between the two prongs, due to one sitting directly in the flame and the other offset, causing current flow and magnetic fields.Anyone got any ideas? |
