Applications
For applications where the standard sensor to DUT socket fixturing methods (discussed in Section 2-17.2,
"Standard Thermocouple Interfacing") are not appropriate, then reference the above Figure 2-13,
"Alternative Thermocouple Attachment," which offers the following selections:
Soldered techniques:
A.
Unsatisfactory:
Junction Does not Contact Solder (Sensor junction is out of direct contact with DUT:
wires first join at point "A," temperature is being measured at point "A")
B.
Better:
Junction Contacts DUT but Thermocouple Wire may conduct heat to or from ambient
C.
Best:
Thermocouple Wire Contacts DUT Surface approximately 20-30 Times Diameter of Sensor Wire
Unsoldered techniques:
1.
Thin
Copper Plate:
Used with Thin Film of Thermal Grease
2.
Adhesive Backed:
Sensor Element Sticks Directly to DUT
