It ended up all the device contained was a thermocouple — that is, an electric thermometer. I have a recursive Select, but the data is not really hierarchical and contains loops. Thermocouple probes have two tiny wires of different metals welded at the tip, most often nickel and chromium (called Type K - described elsewhere on this page). You can test it with a multimeter. In dual thermocouples, separate measuring circuits are contained in the sensor so that each thermocouple signal is independent of the other. When it comes to selecting the right thermocouple wire, it’s all about accuracy, choosing the right calibration type, conductor, insulation and jacket. I will arrange a number of thermocouples as close as possible to each other (spaced < 2mm) in an unsteady, "puffing" flame of a non-premixed gas burner (orifice 0. This voltage translates to the difference in temperature between the hot junction and cold junction. Thermocouples consist of two wire legs made from different metals. Thermocouples offer the greatest temperature range and are more cost effective but are the least sensitive and accurate of the sensor types. Make sure that you have tubing that will allow the water to drip out into the vegetation. Get the thermocouple at 3. Run 2 inches down to bottom of pilot tube & twist around.
