Thermocouple Attachment – What works
Much has been said about various thermocouple attachment methods and how well they work.
What are some common methods of attachment?
Kapton tape
High temperature solder
Aluminum foil – adhesive backed
Aluminum foil – adhesive backed – framed in Kapton tape
Copper foil – adhesive backed
Epoxy – air or uv cured
Temprobe(r) - reusable adjustable probe
Sticky T/C – reusable tape – adhesive backed
“How well they work” depends.
Are they easy to attach? - How long does it take to make a good connection
Are they easy to remove? – Is the thermocouple or product damaged during removal
How stable is the attachment ?- Can I get consistent results over repeated measurements
How accurate is the measurement ? – Does the attachment method interfere with the measurement
Cost – What do the attachment materials cost
Can the attachment materials be reused?�
Can the thermocouple be reused after removal?
