Drag to rotate; pinch to zoom. With the view focused: arrow keys rotate, + / − zoom, 1–3 choose a layer, Home resets rotation and zoom. Step advances to the next layer; Reset returns to the case and default view. Layer buttons select a view directly. The page does not move on its own.
Red and yellow insulation covers the two wires leading to the measuring tip.
Teaching view: The insulated wires run toward a joined measuring tip. Peel away the insulation to follow the two conductors; the voltage between them depends on the measuring and reference temperatures.

The MAX31855 readout conditions the signal and compensates for the reference-junction temperature. [MAX31855 datasheet · Detailed Description]
The readout combines the thermocouple voltage with the reference temperature to calculate the measuring-tip temperature. [MAX31855 datasheet · Detailed Description] [Phoebe’s Field Notes: The Thermocouple Reading That Needs a Second Number]
Teaching view: The wire pair carries the thermocouple voltage to an external readout. The readout combines that voltage with the reference-junction temperature to calculate the measuring-tip temperature.
The two thermocouple conductors use different materials. [MAX31855 datasheet · Detailed Description] [Key Concepts]
The thermocouple voltage depends on the temperature difference between the measuring tip and the reference connection. [MAX31855 datasheet · Detailed Description] [Phoebe’s Field Notes: The Thermocouple Reading That Needs a Second Number]
Teaching view: The copper-colored and silver-colored conductors meet at the measuring tip. The two different materials produce a voltage related to the temperature difference between the measuring and reference junctions.
Explode separates the proposed layers; X-ray makes the case translucent. These are teaching views. No commercial sensor construction or wiring is specified.
